Thermal Resistance & R-ratings

The effectiveness of Insulation materials is measured by their thermal resistance, called R-value. For example, on fiberglass bats there will be a rating like R-13. This means the product has a total thermal resistance of 13. For comparison, the same thickness of wood would have an R-value of approximately 4.0. A plain window typically has an R-value between 1 and 2. An R-value of R-0 would indicate no thermal resistance at all, like an open doorway. When the door is open there is nothing resisting the heat from passing through. Every wall in a house has an R-value that is different based on the thickness of the walls and the number of doors and windows that are installed.

Accredited third party testing lab has calculated values of RetroFoam in typical wall construction to range between 14.5 to 23.7 depending on the thickness of the wall and foam.

Many homes with 2X4 studs can have R-values up to 16.0 when RetroFoam is installed

That means better insulation. This saves you money on utility bills.

Keep your house bundled up with RetroFoam™’s high quality insulation.

The RetroFoam™ insulation difference means your house stays at the right temperature for the right cost.

Here Are a Few of Our Happy Customers...

We were previously troubled by mold in the bedrooms of one particular side of the house. But since the insulation there has been no sign of dampness. The overall temperature of the house remains more constant and the heat from the winter sun is not lost immediately at sunset.

I love RetroFoam™! We’re saving 40% a month on our heating bill! Our home is a renovated farmhouse built in the 1940’s. You could honestly hear the Northern Ohio winds hiss through the walls. Now our house is comfortable to sit in year round and there are no more drafts.

Laura & Rod B.

The house is so much more quiet and easier to heat. We don’t have the drafts we used to have. The RetroFoam™ dealer left my home cleaner than before.      

Dacia S.

Since we had RetroFoam™ installed we noticed the house is much more comfortable. We used to notice the windy days, but now our home is very quiet. We have a bump-out area in the dining room where the floors were always cold, but now we can walk by our bay window in bare feet and the floor is toasty warm.
