Habitat for Humanity Home

We recently completed a new home for Habitat for Humanity in Williamsburg!  It’s a really great cause that helps to get people into their first home. We donated 100% of our materials and Labor for this particular project.  This home is Insulated to Earth Craft standards which consisted of spray foam in the walls and crawl.  Check it out!

(SPI) Spray Foam Insulation by ATLANTIC SPRAY SYSTEMS

Insulation for a 100yr+ house in downtown Richmond, VA. Using all types of foam; close cell for flame and heat sensitive substrates, open cell for the exposed walls and rooflines, and injection foam for walls where original plaster will be preserved.

Insulation for the Treehouse Guys

It’s not every day a really cool project comes along, but when you get a phone call from The Treehouse Guys (think DIY Network) you know it has to be special! We insulated this beautifully crafted treehouse this summer with #sprayfoam! How cool is that?




R value


Assessing Insulation Efficiency

An R-value is a measure of resistance to heat flow: the higher the R-value, the greater the effectiveness of the insulation material being evaluated.

The U.S. Department of Energy has established a set of R-values for different sections of the country based on climate and local energy costs. But in any area, factors affecting an insulation material’s resistance to heat flow include:

  • Material type, thickness and density
  • How the material is installed in the building
  • Where the material is installed
  • Type of heating and cooling system available

Insulation that is compressed will not yield a full-rated R-value. In a multi-layered installation, the R-values of individual layers are figured separately, then added together to arrive at the correct computation. Wall or ceiling insulation will provide a somewhat different R-value than the R-value of the insulation material itself. This is because a certain amount of heat flows around the insulation through studs and joists.

Bottom line: Installing more insulation increases the resistance to heat flow, resulting in higher R-values. And simply stated, higher R-values translate to a more comfortable home environment.
