Foam insulation is the best insulating product on the market today because it maintains it r-value in real world conditions. Architectural Testing stressed fiberglass, open cell, and closed cell foam by exposing the materials to realistic wind and temperature differentials. Foam r-value stayed closer to “advertised” r-values in high, low and moderate temperature tests. See their data graphed below:

Open and closed cell foams are not DIY product – the installation requires a precise mix of chemical hardener and a specific type of resin which generally requires machinery costing tens to hundreds of thousands of dollars. When these compounds are mixed and sprayed into the desired area at the job site they expand to completely fill cracks, gaps, and leaks. This ability to fill cracks and gaps makes foam superior to fiberglass and cellulose.

Filling the gaps in your home saves you money - Oak Ridge National Laboratory stated that “Today, it is estimated that in residential and small commercial buildings, over 50% of the energy loss is associated with heat transfer and air leakage through building envelope components.”

We install both open and closed cell foam – their differences have to be considered when choosing the optimal material for your project:

Foam Properties
Open Cell (ocSPF)	Closed-Cell (CCSPF)
100% expansion rate	30% expansion rate

1/2# pcf density, soft spray foam	2# pcf nominal density, rigid SPF

R-value=3.2-3.9/inch	R-value=6.8 per inch

*Not considered vapor barrier	*Vapor barrier at 2"

*Air barrier at 5 1/2"	*Air barrier at 2"

Water can absorb (up to 40% by volume	Hydrophobic (less than 4%)

Not structural	Offers up to 300% increased racking strength

* - Estimates - refer to manufacturers specifications for actual data

Foam can be used in attics, walls, basements and crawl spaces. Spray applied foam easily covers uneven spacing in the floor joists and is easy to manipulate into areas filled with piping, wiring and duct work without losing thermal performance.

In addition to choosing between open and closed cell foam, our professionals can help you decide whether to foam the roofline or the floor of your attic. They will discuss the various pros and cons of each application with you including cost, the need to bring in combustion air for HVAC equipment, opportunities to add racking strength to your roof in coastal areas, and many more factors.

During your insulation audit our trained professionals will be able to determine if foam insulation is right for you, and what type will be the best insulator for your home.
