Why Cellulose Insulation is Better than Fiberglass Insulation

| 1-888-225-6260

On episode 50 of the On The Job web series, Larry Janesky, owner and founder of Dr. Energy Saver, demonstrates how different types of insulation materials perform when exposed to fire.

In Episode 51, he continues to compare insulation materials, by showing the differences in performance of two types of materials commonly used in attic and wall cavity insulation: fiberglass and cellulose.

Fiberglass insulation is frequently used in the United States, but as this video will show, cellulose insulation outperforms fiberglass in the vast majority of applications.

Cellulose insulation is entirely made of recycled paper: old newspapers, phone books, and paper stock. To make that shredded paper suitable as an insulation material, the cellulose is treated with environmentally-friendly chemicals. In its original state, cellulose is very attractive to insects and known to support mold growth. Boric acid, a harmless chemical used for decades in many household applications as an antiseptic and insect repellent, is used to deter pests and prevent mold growth.

Also since paper is highly flammable, cellulose insulation is treated with a fire-retardant material, making it outperform most types of insulation materials, including fiberglass, in terms of fire resistance.

Using a little display built to compare cellulose and fiberglass, Larry shows how quickly and easily heat passes through a layer of fiberglass insulation when compared to a layer of cellulose insulation. Cellulose is denser than fiberglass and that gives the material a better R-value and makes it better at preventing heat transfer.

That kind of performance makes all the difference during hot summer months when you are trying to keep the scorching heat from the attic from getting into your living space, or during cold days when you are trying to keep the heat from the conditioned area from being transferred to the freezing cold attic.

Another added benefit of cellulose demonstrated in this video is the material's ability to muffle sounds from the street and from one room to another, making your home much quieter.

At Dr. Energy Saver, we use cellulose to insulate a variety of spaces. We dense-pack it into wall cavities, cantilevers, floors over the garage, and we blow it over attic floors. Our customers are always satisfied with the results in terms of added comfort and energy savings.

Our dealers work with most types of insulation and we believe that there is no blanket solution to home insulation, since each material has its own application. We also know that when it comes to energy efficiency, insulation is just one part of the puzzle.
When you call your local Dr. Energy Saver dealer for a home energy audit, the experts will evaluate your whole house and offer you the solutions and materials that will always give you the best results for each dollar you invest.

Attic Insulation: Blown Cellulose vs Fiberglass Batts

| 1-888-215-4188

Attic Systems dealers have been making thousands of homes across the U.S. more comfortable and energy efficient with attic insulation and air sealing.

Why is attic insulation so important? The temperatures in your attic change drastically in the winter and the summer.

Heat radiating from the roof keeps the temperature in your attic in the triple digits most of the season.
If your attic is improperly insulated, your ceiling will become hot and that heat will irradiate through your living areas.

In the wintertime, heat moves from your heated living space into your freezing cold attic.

Proper attic insulation is designed to stop heat flow between your attic and your home.

For that reason, our Attic Systems dealers will often recommend blown cellulose insulation over fiberglass batts.

Cellulose insulation have a higher R-Value than fiberglass, and when blow in an attic, it quick fills all the gaps and nooks.
Fiberglass batts have to be cut to size to fill the cavities and that often leaves many gaps for air and heat to flow through, reducing the R-Value of the Fiberglass even further.

Cellulose is also better at resisting the air flow that fiberglass. Cellulose insulation is also treated with fire retardant and insect repellent chemicals, making it overall safer and longer lasting.

Our Attic Systems dealers are committed to providing always the return for every dollar you invest in attic insulation, and that includes recommending and installing always the best materials.

With an Attic Systems Dealer you are always in good hands!

Cellulose Insulation: 5 Reasons To Use It In Your Attic

Cellulose insulation is a great choice for insulating your attic, especially if your family’s health is important. Blown-in cellulose is recyclable, easy to install and has a high R-value. But is it the perfect solution for your project? Rise CEO Matt Daigle recently installed insulation in his attic and chose blown in cellulose after considering fiberglass insulation, mineral wool, and natural materials. Follow along with footage from Matt’s installation, and his lessons from his tough buying decision.

Why Blown-In Insulation in Your New Home?

Proper insulation increases your home's energy efficiency and air quality while reducing exterior noise levels.

A common blown-in insulation solution is cellulose. Cellulose is blown in wet (looks like wet shredded newspaper) and tends to settle over time, leaving a gap/void along the top section of your exterior wall.

Look for a builder that uses 2X6 framing for exterior walls (2 thicker than the standard 2x4) and insulates using blown-in fiberglass to fill the voids that occur when using standard batts insulation.

Blown-in fiberglass is installed dry, packs tighter, and has a higher R-Value than cellulose. The settling is minimal if any.

If you'd like your home to be as airtight as possible, comfortable, and quiet, we recommend using blown-in fiberglass insulation in all of your exterior walls.

Too much blow in insulation

Sheet rock came down fairly easy with the added weight

This is what happens when you blow cellulose insulation in your walls!

Good for attics, bad for walls.
Use spray foam or batt insulation instead.

Blown-In Insulation

Bob joins insulation contractor Joe Sheridan to witness the process of blowing insulation in behind original plaster walls.


Insulation is important to the comfort and energy efficiency of your home, so let me explain about how Homes By Taber ensures you get the right protection to keep the inside temperatures—hot OR cold—from getting inside.
There are two types of insulation: blown-in and batts. The batts are sheets of insulation that are fitted between the studs, joists, and beams. This is fairly inexpensive, but there can be gaps where the insulation hasn’t adequately filled a space.
Blown-in insulation uses special equipment to blow in or pour the insulation to the necessary spaces—to fill those gaps. The insulation fits tightly into every space, including in and around any obstructions. In other words, no drafts.
Most builders will use an R13-rated insulation here. Homes By Taber uses R-15 because it produces substantially better heat flow reduction, which saves you money on heating and cooling your home.
In the attic, most builders choose to install R-30 insulation. It’s good and it’s reasonably priced. But, we’ve upgraded your home to R44. We put in 47% more insulation into your attic, saving a lot of money that would otherwise be spent on wasted energy.

Insulating the House- Cellulose Densepack and Blown Attic

Insulating the House- Cellulose Densepack and Blown Attic

I'll be the first to say, this is my first experience with blowing cellulose and with the densepack method. I like both just fine, albeit a bit messy. Just this silly little Free blower was a total POS.

All of my design planning as far as the hose adapters/reductions worked fine for the most part. Id get the occasional plug, which was usually due to the machine just not having the guts to clear it.

Time is what killed us here. This little machine, best I can tell, is rated for ~300 lbs/hr, in an ideal situation. We didn't get anywhere near that. Maybe I got 150 lbs/hr, maybe....I was looking at some bigger commercial units that are rated to crank out 3000 lbs/hr! Now that's living!

The idea of densepack is that you will cram insulation into every nook and cranny. This is hard to do with fiberglass, and even spray in cellulose can leave voids behind pipes and boxes. Conceptually, densepack is a good idea I believe. Perhaps it's better designed for remedial jobs. Just fought this stupid blower the whole time : (

In the end we got tired of blowing it away, and did not get the placement we desired. We returned over 100 bales of the original 288 that we had delivered out. I calculated ~275 bales based on the manufacturers spec sheet for my walls and attic. We rounded up to 288 for even pallet numbers, and I figured I'd just wasted the extra in the attic. I definitely never planned to return over 100 bales!
