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.

5 Reasons to Use Cellulose Insulation in Your Attic (and 1 Reason Not to)

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.

Cellulose Insulation versus Fiberglass Insulation

A short video comparing the thermal effectiveness of cellulose versus fiberglass insulation. These are both blown insulation types. The cellulose proves itself to be far more effective at slowing the transfer of heat through a modeled attic.

It's known that the average R Value (R Value is the measure of Resistance to Heat Flow of an insulation type) of cellulose insulation is about R 3.5, and the average R Value of blown fiberglass is about R 2.5. I say about because there is a slight range in R-Values depending on the density of the insulation. In this case I used the average of the R Values. This means that cellulose has an R Value that is approximately 40% higher than blown fiberglass. That in itself sounds reason enough to steer clear of using blown fiberglass (there are other reasons). But when you watch this video the huge difference in effectiveness comes into light.

Mobile Test Lab: Dense pack blown-in cellulose insulation

As part of the new Mobile Test Lab (MTL) research on insulation, Dick Divelbiss of Thermo-Kool of Alaska dense pack blown-in cellulose insulation in both interior and exterior of the walls. He demonstrates how to dense pack walls using blown-in cellulose to achieve tight house envelop.

Blow-In Blanket System (BIBS) - Blouin Brothers Insulation

This video is part of our insulation application series
Part 1: Batt Insulation
Part 2: Blown-In Blanket System (BIBS)
Part 3: Spray Foam

The Blow-in-Blanket System (BIBS) is a unique state of the art insulation system that uses loose fill fiberglass insulation to manufacture a seamless blanket of insulation in cathedral ceilings, floors, framed walls, basements and more. The Blow-In-Blanket System is achieved by blowing a loose fill fiberglass through a hose and out a nozzle into the cavity behind a fiber mesh netting that is precisely attached to the studs.

Two Blow-in Insulation options at Home Depot

Your choices are GreenFiber Cellulose Blown-In insulation, or AttiCat Fiberglass Blown-In insulation by Owens Corning. I made this just to give people a heads up on the insulation options at Home Depot. Lowe's has a similar option. If you get a handyman or contractor to blow in the insulation, chances are he will blow in the cellulose insulation. Its shredded up newspapers and phone books, at least 80%. If you like to recycle then use that one. I think the fiberglass is much better because it does not compress over time as much. However, professional installers may ad a starch glue if they are blowing it into vertical spaces like wall cavities. The glue helps it hold its position. So if you are hiring out be sure to ask the exact process they use. Late October/Early November Lowe's and Home Depot both have the fiberglass on sale at 20% off. So it would be worth it to hold out for the sale if possible. To see what Lowe's has click this link:

How to Insulate with Blown Insulation Before Drywall

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!
