The Importance of Insulation R Value

Home insulation is a vital component of the home that you should consider, particularly during house renovation. If the home is not properly insulated, rest assured that insulation will be the most effective method to reduce your electrical energy usage. It is a proven fact that an insulated home is much more energy efficient, as the air conditioning in your home can substantially be decreased. Other than saving energy, home insulation also makes your home more comfortable to live in and helps to muffle sound. Dust and pests may also have a difficult time to come in your own home via the insulated doorway and basement.

An important consideration in insulation is the insulation R number. The R number indicates the efficiency of insulation material. The higher the R value, the more successful the material will be in lowering electricity usage. If you are planning to add insulation to your home and discover that there are already existing insulation, all that is required is to add an additional layer of insulation on top of your existing level. The insulation R value for existing insulation can be estimated by multiplying the thickness with a fixed number, which is dependent on the type of materials.

There are many types of home insulation available for power saving purposes. Probably the most common kinds are clothes insulation, paper insulation and wool insulation. In South Africa, mostly it will only be the ceiling that requires insulation, although insulating windows with double glazing is also a good idea in some areas.

Although the cost of installing insulation might be high initially, the money saved through lesser electricity usage is quite substantial in the long run. The required insulation R factor is an important parameter that needs to be estimated during the set up process. All recognized insulation materials will indicate the R value on the packaging. In colder areas you would require a higher R value than in warmer regions to achieve the same result.

The Importance of Safety Whatever Ceiling Insulation Types You Choose

When you are in a quest to saving energy at your place, ceiling insulation is one of the best things you can do. Ceiling insulation will reduce your energy consumption which will result in lowering of your monthly heating or cooling costs. With proper insulation, you will be assured that you will be able to enjoy the kind of temperature you want your home to have, in just a short amount of time. This is because proper insulation would ensure that your heating or cooling system will be able to function at its best. You would also be increasing the value of your place just in case you are planning to sell it. With the kind of benefits you can derive from it though, you still need to understand its safety considerations. No matter what kind of ceiling insulation types you choose to install at your place, you have to take certain measures to ensure the safety of your house and your family.

People in certain parts of the world are getting more and more concerned with fires that are started by wrongly installed insulation. Though many manufacturers would claim that certain ceiling insulation types are fire resistant, it is only to a certain degree. Such materials that are suppose to resist fire, will eventually give in, under different circumstances.

With the many fire reports that have been broadcasts in the television, newspapers and through the internet that have been caused by ceiling insulation, most of them are due to these ceiling insulation types that are installed too close to certain devices and electrical equipment. Because of this, you should take note that there should be a minimum distance between the ceiling insulation and certain items at your home. For example, the ceiling insulation should be at least 50mm apart from standard household light bulbs or incandescent lamps. If you are using halogen lamps, it should be farther away, such as at least 200 mm around it.

In addition to the distance, it is also highly advised to properly choose the kind of material you would be using in installing your ceiling insulation. It is best that you choose the kind of ceiling insulation that receives a higher heat resistance rating. This way, you are increasing the safety of your home by observing proper distance, as well as buying the material that can provide you with utmost safety.

Another cause of fire due to ceiling insulation is the incorrect way of installing it. Therefore, if you are not absolutely sure of yourself in installing it, then the best way to go about it is hiring an expert to do it for you. One of the best ideas in doing this is to search for a reliable company at your town, which is known to provide excellent service in terms of installing different types of ceiling insulation.

If you have just move to a new place in which the previous owner already installed ceiling insulation, you should have a professional ceiling insulation installer have a look at it. This way, he will be able to see if there are certain adjustments or enhancements you need to have to increase the safety of your place. Whatever kind of ceiling insulation types that have been already installed at your place, it is always best to have it checked to be on the safe side.

Ceiling Insulation – Good Reasons and Examples

Having ceiling insulation is not a way of decorating or improving its aesthetics but an essential ingredient that hikes up the comfort levels in your home. It is essential to have the ceiling insulated to prevent heat dissipation in cold weather so as to keep the inside of the house warm and cozy.

It is a great way to save on fuel and electricity bills which shoot up during winter when you use the heating systems indiscriminately in a bid to stay warm. The resistance to heat dissipation that is provided by the insulating materials prevents the accumulated heat within the house from waning and seeping out through the ceiling.

Having an insulated ceiling helps keep the inside of your house warm in cold weather conditions and cool in the summer. The most obvious benefit is of course the cutting down on electricity bills and the energy saving that you would achieve by doing so. It would also mean that you contribute in a small measure towards alleviating the energy crisis and also help towards environmental protection. There are numerous ways of insulating your ceiling properly and deriving optimum benefits from it.

The hot air that is generated from the heating source in the house would tend to rise up to the ceiling trying to dissipate the heat through the roof material to cool itself off. Having a ceiling insulation prevents the air from losing its heat and keeps the temperature of the home’s interior intact. The warm air is prevented from dissipating its heat thereby maintaining the room temperature without over using the heating system.

Fiberglass batt insulation is a simple and easy way to insulate your ceiling and is easy to be done. You do not require the services of an insulating technician and can do it on your own. It is also the most effective type of insulation to prevent heat dissipation. But although effective, the method of ceiling insulation is not very cost effective. If you fancy yourself to be a bit of a handyman, you could do the installation by yourself. The only thing you need to take is to not close any vents and to install it tight enough so as to leave no gaps in between.

The residential foam insulation is a more expensive option for insulating the ceiling but is durable and long lasting and you can gain value for the money spent over a longer period of time by saving on your heating and electricity bills. The foam insulation spreads to any area that is susceptible to heat loss and covers it up. The application procedure is simple and you can do it using a spray. Foam would not be good for homes that are not ventilated enough as it collects the damp and cause the walls and the ceiling to mildew over time.

A lesser expensive option for insulating your ceiling is the fiberglass blown insulation which is also less effective and cannot be installed by you yourself but has to be done by professional installers.

This form is however less efficient but better results can be achieved by using a double layered ceiling insulation of this form. Though expensive it would work out cheaper than the batt system of insulation any day. The material used for insulating your ceiling could either be fiberglass, cellulose or Rockwool, all of which work pretty well.

Ceiling Insulation In Warm And Cold Climates

Choosing the very best good quality ceiling insulation is the most effective point that you possibly can do, regardless with the type of climate you live in. It plays a very essential part in any house, regardless of size, or warm or cold weather.

Thankfully, consumers are blessed with a wide array of choices regarding insulation. So they could be picky as to what they install. Its purpose would be to preserve the cold from coming into your home, and preserving the heat inside. To the other hand, it’s going to hold your house from becoming excessively warm inside the summer months. That means you is going to be saving cash all year round on all kinds of vitality consumption. It is going to reduce your heating bills in the winter and your air-conditioning bills inside the summer.

Without good-quality ceiling insulation, you will be paying a lot extra cash in heating and cooling charges. So, not only is it good for your own sake, it’s also fine for the environment as you will be consuming much less energy and creating a lesser amount of greenhouse gases.

You will need to inform yourself on the matter so that you can be a smart consumer. Know all about your subject and about each and every particular solution. Weigh out the pros and cons of each one particular, and calculate the cost. When some could need the know-how of an experienced installer, others may well really be established through the house owner.

It is imperative that the insulation be put in as the manufacturer suggests, and handled with care to avoid its integrity from being compromised. If its, you might not be getting all the benefits out of it.

Blown insulation is among the least expensive choices in insulating ceilings. Unfortunately, it is also much less successful than other solutions, and must be established by professionals. About the other hand, fiberglass insulation may be set up by yourself, and performs incredibly nicely. Thus, you’ll be getting a great top quality product that is certainly quite inexpensive, and you can install on your personal to save even a lot more income.

Protect Your House Thoroughly With Insulation Boards

Insulation is any material or substance that provides a high resistance to the flow of heat from one surface to another. The single idea or premise that insulation is based on comes from heat moving from a warm area to a cold area. In the warmer times, heat tries to enter the house and on the colder days, the heat tries to escape. With vagaries like these, the purpose of insulation is to regulate the temperature by reducing the pace of the process. One way for some effective insulation is the method of absorbed insulation. These use materials such as aluminum foil and polyethylene foam which can be helpful in preventing the accumulation of cold and hot air and reducing heat transfer.

There are other forms of regulating the temperature too, in the insulation field. These are called the insulation boards. There are three forms of foam board products under several manufacturers names. They include extruded polystyrene, expanded polystyrene and foil faced or polyisocyanates unfaced. These boards are explained in detail below:

Extruded Polystyrene Foam or XPS is popularly known as the pink board or the blue board in edge profiles and in different thicknesses. This board is one of the most widely used insulation boards in the residential construction industry. XPS has an R value (measure of thermal resistance) of 4.5 to 5.0 per inch thickness. It is reasonably priced, light and easy to use. The product can be used to insulate the outside of foundation walls and even under the slabs of concrete.

Expanded Polystyrene Foam or EPS is the least used, cheapest quality foam available in the construction industry. The product may have an R value of 3.6 to 4.0 inches thick. This type of insulation boards is very similar to the foam which is used for packing “peanuts” and is used in insulated concrete form also known as ICFs.

Polyisocyanurate also known as polysio, is usually observed in all kinds of commercial and more recently with residential building projects. It has an R value of 7.0 to 8.0 inch of thickness. It also has a foil faced. The foil makes it excellent for insulation boards when radiant heat is involved. It is also the most expensive board, amongst the three.

Although foam boards are much more expensive compared to other insulation materials, such as cellulose or iberglass, it is mostly used in places where space limitations are encountered. Another reason for preference is, it is three times thicker than most of the insulating materials and because it has high R values. Also with materials such as polystyrene sheets, give a more peaceful and subdued home since, it prevents the entry of unnecessary noise. The house can have a sobering effect and can drastically reduce the cost of electricity. There are a number of stores both on-line and off-line that one may visit for the precise boards for the perfect fit!

Make winter more bearable with ceiling insulation

It seems every winter is getting colder and colder. Whether that is a real concern or not is debatable. One thing is certain though… in South Africa we can learn a lot from countries with more extreme winter weather. For starters, they know how to insulate themselves!

Most South African homes have very little in terms of insulation compared to their European or North American counterparts. There are multiple reasons for this, but allow me to highlight perhaps the two most prominent ones. Firstly is the fact that traditionally South Africans paid very little for energy compared to the rest of the world, which means that it always used to be cheaper to heat the home rather that preventing it from going cold in the first place. Secondly is the fact that winter temperatures in South Africa are a lot more moderate than elsewhere. We are not so prone to constant periods of snow, which combined with wind cause for massive drops in temperatures.

However, we are well aware of average temperatures dropping severely in winter – unbearably so, and certainly enough to require heating. With sharp increases in electricity tariffs, this quickly has a dramatic impact on the finances, and this is why nowadays it makes a lot more sense than ten years ago to insulate our homes properly. An home without insulation loses heat up to 240% faster than a home that is well insulated. This means that a home without insulation requires more constant heating than one with insulation. It is much like sleeping under a single thin blanket in winter instead of a thick duvet. With only body heat you will be fine under the duvet, but the thin blanket will require an electric blanket, since the heat will escape too quickly to be sufficient.

Ceiling insulation is a great place to start when insulating, because warm air rises. When the warm air inside your house rises to the ceiling, a well-insulated ceiling will stop the warm air and start pushing it down eventually, instead of acting like a chimney that extracts the hot air and allowing more cold air to start cycling through your home.

The next question is which installer to get. How do you know who to trust? We hear every day of contractors running off without finishing the job, or not standing responsible for a job that wasn’t done properly. Wouldn’t it be great to know about reputable and trustworthy ceiling insulation installers in your area? Well, Ensav has great news, because we’ve got exactly what you are looking for.

BUSINESS DAY TV: A geyser is like ‘a giant kettle on standby all day

COSTAS Souris is director of GESS Green.

BUSINESS DAY TV: Coping with Eskom is a sad reality for homeowners as they’re left to fend for themselves. So what do we do … is an inverter better than a generator and what are the cost implications, and what’s best for people living in a townhouse or a cluster. Joining me now on News Leader is residential green expert Costas Souris from GESS Green.

Costas, have you seen a huge uptick in your business over the past few months?

COSTAS SOURIS: Most definitely. The only problem is we don’t have the stock and people are on us all the time about stock and that is across the board with all suppliers.

BDTV: What is the time delay then?

CS: You’re talking about two to six weeks depending on the type of solution you’re looking at.

BDTV: Okay, so this is a national problem but I want to get on to an inverter … in simple one-on-one terms, what does an inverter do?

CS: When the lights go out, something needs to power those essentials in your life, the TV, the decoder, the cellphone charger … you need to make an emergency call and you can’t do it … certain lights in the house, your ADSL router, your PC, your laptop, those essentials. And then, of course, you can go to the next level, and you can say I need to power my fridge, my gate motor, my alarm, my fence and so forth.

BDTV: So an inverter would deal with daily comforts like TV and cellphone?

CS: You can size an inverter based on your requirements. Here we need to bring in generators because you can bring in a generator which can power up your whole house, and you can also do the same thing with an inverter. But when we look at an inverter we tend to look at it from an essential items perspective.

BDTV: Okay, so if you had to compare an inverter for the whole house versus a generator for the whole house, what is the cost, and we’re going to get into the environmental implications just now?

CS: You’re looking at R100,000 for an inverter to power the whole house and you’re looking at probably R120,000–R140,000 for a generator.

BDTV: But the inverter is obviously cleaner….

CS: Definitely cleaner … it’s clean energy, it’s more convenient, it doesn’t have any noise attached to it other than a fan when it’s charging itself … and it can be inside … whereas a generator is noisy, smelly, and you can hear from what I’m saying that I’m not too much of a fan of generators.

BDTV: I know and I think its huge environmental (impact) … and it’s just rude to all your neighbours out there. So, if you’re on a budget and you just wanted an inverter for your cellphone, your TV, just to give you a bit of comfort when load-shedding happens, how much would that cost?

CS: It’s somewhere between R3,500 and R10,000, depending on exactly how many appliances you want to put on. The thing to do is to look at the labels on each of the appliances, the cellphone, etc and say, okay, that’s 7W, the TV is 150W and add it all together and it will tell you what size inverter your should be looking at. You don’t want to buy an inverter that’s too small that will trip out like your earth leakage if you overdo it. And, of course, you want it to last, you want to make sure that, come the four to six hours of load-shedding, that you want to get through that.

BDTV: So how easy it for impractical people to put an inverter in their homes?

CS: There are two types you can look at, one is what we call a plug-and-play version, which we’ve just been discussing, which you essentially plug … into the wall, let Eskom charge it for you, and then plug the appliances into that box. Let’s just call it a box, which is really not that … big … two car batteries together, and let it turn on when Eskom goes off, and let it run your TV. So all you’ll see is a slight flicker on your TV and life will just carry on.

BDTV: Yes … it really does make sense and (it) seems … your preference is an inverter over a generator.

CS: For the smaller things definitely.

BDTV: Yes, but for bigger things like, what, fridges, pool pumps….

CS: If you’re looking at bigger appliances that draw more power, more watts, then you need to really consider for how long do you want to keep those running, and there’s the big plus of a generator. A generator has got a fuel tank … you can put in a long-range fuel tank, and … fill it up and keep (filling) … it up.

BDTV: But I am so anti-generators because I think it’s rude to your neighbours, especially living in a townhouse complex and I live in a cluster complex and two of the eight units have generators. When Eskom rears its ugly head … it’s awful, the fumes and the noise. So what should people in townhouse complexes be doing, inverters?

CS: You’re answering the question … look at an inverter, which is very similar to what we’re using in offices for UPSs (uninterrupted power supplies) which make sure your computer retains all its information and keeps running when the power goes off. That’s what an inverter does and you can size it up if you need to.

BDTV: Let’s go onto other quick ones … quick ones to reduce your power load. You’re saying that the most expensive in terms of electricity usage in your house is a hot shower.

CS: Definitely. Think about a kettle … when you put a cup of water in a kettle it takes a few seconds to boil. When you add to it and fill it up to the top it takes minutes to boil and that element in the kettle is drawing 2,000-2,500W … now think of your geyser, it’s a giant kettle on standby all day, going on, off, on, off, all day. It’s costing you money.

BDTV: What should we do then?

CS: You should be switching to renewable energy, what we talk about all the time, solar water heating, and not to be confused with photovoltaic or PV panels which are used to generate electricity.

BDTV: How much is a solar water heater?

CS: It depends again on size … they vary in price from R10,000 to typically R25,000.

BDTV: What does a three-bedroomed house need?

CS: Rather ask me the question, how many people live in the house?

BDTV: A family of four.

CS: For a family of four, I would be looking for a 200l or 300l solar water heater and that’s between R15,000 and R20,000.

BDTV: Are there any subsidies on that, anymore?

CS: That’s the net price, and people need to move on it because at the end of April Eskom is withdrawing their subsidies and the Department of Energy is bringing in something new. What it is the industry doesn’t know yet?

BDTV: How much is the present subsidy?

CS: The present subsidy on a 300l system is R8,964 which is a lot of money.

BDTV: Yes, and it’s quite a chunk of the total price.

CS: It is.

BDTV: So that is something one can definitely look at. What about heating, what are the options there?

CS: Just before we move on, when looking at solar heating you reduce your electricity by about 30%-35% of your total bill.

BDTV: Okay, so that’s definitely something to look at. Heating in winter, what should we be doing?

CS: The first thing to be doing is to put a hat on your roof … put some ceiling insulation in. you have some very expensive homes with no ceiling insulation….

BDTV: How much is that?

CS: It’s round about R60/m² installed so a 100/m² home … (about R6,000).

BDTV: I have to ask you … we’re running out of time. The dreaded pool pump, what can we do about that?

CS: Reduce the hours. In summer three to four hours, and in winter one hour. After that you’re polishing the floor with the creepy.

BDTV: This is amazing stuff….

How to install ceiling insulation

How ceiling insulation works
Ceiling insulation is designed to reduce the transfer of heat through the ceiling. Heat naturally flows from warm to cool areas, particularly through ceilings.

During the winter months, the heat inside a home is lost through the ceiling, walls and windows and we resort to energy to heat a home. With the installation of ceiling insulation, an effective level of insulation reduces our demand for energy and lowers our monthly energy costs.

There is a right and a wrong way of installing ceiling installation.

If the material is too compressed it provides less resistance to heat flow. Properly installed ceiling insulation should be laid in its natural, fluffed form without potential air cavities.

As a DIY project, adding ceiling insulation is fairly simple to do and your local hardware store should offer standard material as well as the tools needed to set it up.

You will need:
Ceiling insulation – enough to cover the entire floor space*
Safety clothing – dust mask, safety glasses, long-sleeved T-shirt and pants
Utility knife
Tape measure
Knee board – large enough to span two tie beams or joists**
Portable light

Before you start…
*Glass fibres do not present a health risk. They may, however, cause itchiness (similar to that caused by grass). It is advisable to wear gloves when installing fibre-glass insulation. In the case of itching, wash affected area with warm, soapy water.

*Be careful where you walk. Only walk on larger tie beams or joists and use a knee board that spans beams for sitting.

*The easiest way to determine how much insulation is required is to measure the perimeter of the house. For example: If the house is 9 metres long and 10 metres wide = 90 square metres of ceiling insulation is necessary.

*A tie beam or joist is a horizontal span of timber that runs from wall to wall to support a ceiling or roof. An off cut of timber that spans two joists can be used as a knee board.

Here’s how:

1. Working with one roll at a time, and starting at a far corner of the ceiling space, you need to cut the ceiling insulation so that it fits between the tie beams or joists.

Measure the distance between beams using a tape measure. While still in the bag, cut insulation roll to the required size. The roll should be cut 50 mm more than the distance between the beams.

2. Remove the insulation from the bag and roll out between the tie beams ensuring that it fits tightly between the beams.

Do not press the material as you lay, simply place on top of the ceiling and allow it to retain its original form. This is important as pressing down will reduce the resistance. For the same reason, it is also important to ensure that there are no gaps between cut strips.

3.  Cut the insulation out around trap doors and fix the cut section to the trap door using good quality contact adhesive.

Leave a 50mm gap around motors, or electrical fixtures.

It is advisable to lay the insulation underneath any wiring and to cut around any down lights to allow heat to escape.

5 Advantages of choosing Blow In Insulation

Insulating your home is real and simple the number one way to save money on energy expenses. In the old days surfaces and wall space were lined with just about anything to keep the moisture and cold air out of residence. Renovations have got revealed that also old papers were identified packed in to wall and also floor boards.

Today insulating is a research all its personal. There are R-factors allotted to different materials and methods of insulating that give homes and also buildings an appropriate amount of protection for their geographic location. The higher the R rating, the greater insulated the home.

One of the top rated insulations is relatively not used to the industry — probably no more than a couple of years old : and that is blow in insulating material.

The Benefits of Blow In Insulating material

There are several rewards to whack in insulation over rolls of grp insulation. The benefits include the method of installing it, the energy efficiency and exactly where it can be used. Listed below are the top Five reasons to consider utilising blow inside insulation:

  1. Blow within insulation can be adjusted. Depending on simply how much material is utilized, it can develop a protection by having an R price of 15-38.
  2. Only virgin supplies are used to generate most blow-in kinds of insulation. What this means is there a reduced chance of allergic reactions.
  3. Coming the material into the crevices enables a tighter fit and close up. It can be directed around 4 corners, beams, or perhaps wiring which could already be in the walls.
  4. Installing whack in insulation is quickly. A buffer, referred to as any blanket is actually stapled to all of the 2x4s to keep the material through floating away and adhering where this isn’t wanted. Then the small slit is cut to the blanket. A hose will be inserted as well as measured numbers of the insulating material are taken into place.
  5. This kind of insulation is extremely energy efficient. As it is blown inside it expands and adheres towards the surrounding surfaces. It floods even the smallest of breaks as it performs this.

The Complete Installment Process

Right after attaching the actual blanket for the surrounding boards, the small starting cut in it allows the particular hose being pointed in all directions around the wall or threshold. After the substance is in put the blanket’s slit is sealed and recorded. This blanket does not become a dampness barrier, it simply control the particular spray. The fabric itself resists wetness.

Drywall or other wall materials are then set up right over the insulation blanket. In a renovation project which means that an entire walls would not must be removed to be able to insulation. Take an extremely old home for example. There may be simply no insulation whatsoever. Instead of getting rid of layers regarding plaster wall, you can simply make an opening, position the particular hose and also fill the actual walls will certainly energy efficient insulation. Then patch the wall structure and the career is complete.

The setback in insulation is more expensive compared to traditional insulation. However, specialists estimate in which energy cost savings is so fantastic that inside 2 to 4 a long time those expenses are recovered.

Recycled cellulose insulation

Cellulose insulation is a recycled newspaper product that cuts energy costs while creating minimal environmental impacts.

Cellulose insulation is an environmental double whammy — a recycled energy saver. It uses recycled newspaper fibers to make a foam-like material that can cut energy usage and costs. The foam is typically blown into attics, either as the first layer of insulation or as additional layers. It acts as a heat block, keeping warm air inside during the winter and outside during the summer. Cellulose insulation also can be added in walls without existing insulation, or under floors.

Green Fiber is the leading maker of recycled cellulose insulation. Home improvement stores sell Green Fiber insulation bags for less than $15. Green Fiber has a calculator to determine specific project needs, but a bag fills about 12 square feet of uninsulated attic space to an insulation value of R-49 (the federal suggested minimum for attics in most of the United States).

Stores typically rent blowers for do-it-yourself jobs. Two people can fill an attic with insulation in a weekend (one person runs the machine while the other holds the hose and blows in the foam). Many general contractors and specialists also blow in cellulose insulation.

Insulation upgrades qualify for federal tax credits that cover 30 percent of the insulation purchase, up to $1,500. Installation costs are not included. Most types of insulation qualify, so why choose recycled cellulose insulation? Here are the drawbacks and benefits:


Newspaper is very flammable, but the insulation is treated with fire retardant. Still, cellulose insulation can be a safety hazard. When thick cellulose insulation settles on a recessed light fixture, it traps the heat and could start a fire.

The simple solution is doing some prep work in the attic. Install 10 inches of flashing around light fixtures to keep the insulation away from the heat. Also put chutes around attic vents to ensure proper ventilation. For convenience, also mark off the attic entry hatch with a cardboard frame to make sure you fill around the hatch without covering it.

Personal Benefits

  • Cellulose insulation is healthier than some alternatives. Fiberglass is a skin irritant and it may emit formaldehyde. Dense polyurethane foam is constructed with fossil fuels, and is toxic during installation.
  • Cellulose insulation provides more insulation per square inch than standard fiberglass insulation. In some situations, cellulose may be more cost-effective.
  • Blown-in insulation can insulate small spaces and gaps that are hard to reach or cannot be properly covered with fiberglass batts.

Environmental Benefits

  • Cellulose insulation manufacturing is relatively simple, requiring few inputs and little production energy.
  • Cellulose has more recycled content than other insulation products. It is generally 80 percent recycled newsprint and 20 percent non-toxic fire retardants.
  • Leftover scrap can be recycled, unlike fiberglass and other insulation types.
  • GreenFiber and other companies rely on local materials and only ship to local areas from each factory, which reduces energy costs for transportation.

Take advantage of tax credits and energy savings with cellulose, possibly the healthiest and most environmentally responsible insulation option.
