Wet sprayed blown high efficiency Polyicynene Polyurethane foam insulation

While previous generations may have been content to live in drafty houses, most people now want comfortable warm houses. A healthy house today is well-sealed, well-insulated and properly ventilated.

We did not include fiberglass insulation here, and actually not even cellulose insulation; Once you do your homework, like we did, we believe you will also come to the same conclusion: Wet blown foam insulation is by far your best option to a healthy, energy efficient home envelope.

BioBased

BioBase 501 is a revolutionary new insulation product. It is a soy bean based spray-in-place polyurethane foam insulation that creates an internal cavity, insulated, wind-proof barrier.

The advantages of foam insulation, such as BioBase 501, are highly recognized by building professionals and the building science community. It is the most environmentally friendly insulation in the industry, while remaining very cost-effective.

Read more on the multiple advantages.

Recently named the "Outstanding Product of the Year" by the NAHB in 2004.

Demilec

SEALECTION 500 is an insulation breakthrough. Spray applied as a liquid, it expands within seconds to 120 times its volume to fill every nook and cranny providing superior energy efficiency and improved indoor air quality by eliminating air movement through walls.

It is non-toxic, does not off-gas and meets all building code requirements. The insulation reduces airborne noise and dust making it the healthy choice for those who suffer from allergies, asthma or chemical sensitivity, and is the smart choice for healthy living.

The web site needs a little work, but we were able to find good information on a page named healthy living, and a bit more technical useful data here.

Worst web site among the three mentioned here.

Icynene

"Icynene is the leading producer and marketer of light-density foam insulation for the global building industry, and sooner or later every building will have it" so they say.

Icynene®, the leading soft foam insulation and air barrier system, is becoming the industry standard for providing maximum building envelope performance. Icynene’s pour and spray formulations represent a breakthrough in the science of moisture and thermal management.

Icynene® is the leading 100% water-blown foam insulation that minimizes air leakage for increased energy efficiency, creates a healthier indoor environment, reduces airborne sounds and offers greater design freedom. Icynene® maintains its performance with no loss of R-value over time. It does not shrink, sag or settle. Icynene® adheres to most construction materials and is the perfect insulation for walls, attics, ceilings and floors.

The manufacturer also now offers pour fill variation; It is an insulation and air barrier that injects the latest building technology into an older building to maximize energy efficiency while still preserving its original architectural details. Icynene® fills the wall cavity completely, starting at the bottom and slowly expanding upwards to 60 times its initial volume. Since Icynene expands in the direction of least resistance, it will not expand outward and damage the wall. The pour fill formula has an R-value of 4 per inch.

One of the most comprehensive, informative and well-built web site of any manufacturer.
