Beantown Insulation

Conventional fiberglass building insulation works by its ability to trap air. To reduce conductive and convective forces, insulation must create dead air space. Fiberglass relies on the air trapped between the glass fibers to give its R-value or thermal resistance.  In essence, the thicker the insulation, the more trapped air you have and the greater the insulation value. 

 

Dead air space is the key term here, especially with traditional fiberglass batts. Now here’s the kicker. Are you sitting down now?  Seriously?  Studies have shown that with a 9-mph wind, this light breeze, which in New England we always seem to have, can reduce the R-value of your traditional fiberglass insulation by roughly 63%!  Now if that didn’t sink in the first time go ahead and read it again.  Still it gets worse.  If your insulation is also wet, maybe because the exterior of you home was not properly protected with a house wrap or a leaky roof has allowed water in, then your R-value basically drops to zero.  Remember fiberglass depends on trapped air for it to have any R-value at all.

 

So what is Cellulose insulation?

Cellulose insulation is made from recycled paper and contains nontoxic Borate, an acid produced in nature.  The addition of Borate acts as a flame-retardant and additionally makes cellulose pest and mold resistant. It is by far the least polluting and most energy efficient of all applied insulation materials.

 

How does Cellulose work?

Cellulose insulation is applied by being blown into exterior or interior wall cavities and into attics and crawl spaces.  Now, if your exterior wall already has fiberglass insulation in it, then you can’t blow in cellulose insulation over it.  This is why Beantown Home Improvements offers a premium insulated vinyl siding product to add additional insulation to your walls.

 

Now if your exterior walls are not insulated, then pressure packing or blowing in cellulose insulation through small holes in the exterior wall is a great first step.  When applied properly your cavity walls are packed with cellulose leaving no air pockets, therefore drastically reducing air flow and achieving a greater R-value.

BEANTOWN Home Improvements has worked with homeowners over the years to not only insulate their walls & attics, but also their wallets. 

 

From our experience one of the best times to insulate your walls is during the process of re-siding your home, and BEANTOWN does it all.  Since all of the old siding will be removed (we never go over old siding) and the wall sheathing expsosed, it's quite cost effective to have cellulose insulation blown into your walls and then covered with yet another layer of protection, our Premium Insulated Siding products.  You would be surprised how much more energy efficienct your walls will be when we're done with them!

 

 

Here is Some additional Food for Thought - THINK GREEN

 

  • Cellulose insulation manufactured from recycled paper is the least polluting and most energy efficient.

  • Cellulose has the highest post-consumer recycled content. The fiberglass industry averages 35% recycled glass, while the cellulose industry averages a minimum of 75% recycled content.

  • It takes more than 10 times more energy to produce fiberglass insulation as cellulose insulation.

  • Due to air circulation and natural convection, the R-value of blown in fiberglass insulation decreases by as much as 50% as the temperature drops from 45º degrees Fahrenheit to 18º degrees Fahrenheit.

  • In contrast to fiberglass, cellulose has a better resistance to air flow and prevents the upward movement of air caused by temperature differences {the R-value of Cellulose actually improves during cold weather}. Heat flow problems associated with fiberglass make cellulose an attractive alternative.

  • Substantial and well-documented public health threats are associated with fiberglass. Fiberglass insulation is required to carry a cancer warning label in compliance with OSHA's Hazard Communication Standard.

  • No adverse health effects from cellulose insulation have been identified.
