People often ask the difference between open-cell foam and the closed-cell spray foam we use. The advantages of closed-cell foam include its strength, higher R-value, and a much greater resistance to air and moisture. Open-cell foam has tiny cells that aren't completely closed. The cells fill with air making the foam weaker and softer (think angel food cake) only offering an R-value of around 3.5 per inch. Closed-cell differs in that all of its tiny cells are closed and packed together, making it rigid. The cells are filled with a gas that helps the foam rise and expand, and become a greater insulator,
offering an R-7 per inch.
Double the R-value!
There's no debate when it comes to "green" insulation, cellulose is the only choice. It's manufactured from 100% post consumer recycled fibers. They reduce the largest single component of the residential waste stream, scrap paper, and turn it into all natural cellulose insulation. It requires much less energy to produce so the carbon footprint is the smallest in the industry. It's one of the most cost effective types of insulation with an R-value of around 3.5 per inch. As if all that wasn't convincing enough, Energy Control offers a LIFETIME WARRANTY on their cellulose insulation. "Pass on the pink stuff when you pick insulation." Indeed! Choose green!
Fiberglass is the type of insulation most people think of when they think insulation. We've all seen the commercials with the Pink Panther, but not all fiberglass is pink. Owens Corning added it to their product years ago to set them apart in the industry. It is a good option for insulation, not only because of the price but also because you can choose your R-value, up to an R-38.
The next big thing for new construction and renovations is our hybrid Flash-n-Batt Method which includes a layer of spray foam to seal the wall and fiberglass batt to fill the cavity. It's more cost effective than all foam alone and offers a higher R-value. Yeah, we do that.
