We’ve long touted the energy-saving aspect of PROSOCO R-GUARD Air & Water-Resistive Barriers. As proof, we site the study by the National Institute of Standards & Technology, NIST 7238, which found that an effective air barrier can reduce a building’s energy costs by more than 40 percent.
And we know R-GUARD is effective, because it meets the four checkpoints for an effective air barrier — continuous, structural, durable, breathable.
What we haven’t had is a case where someone actually documented their energy costs before and after an R-GUARD installation.
I recently learned, via our Great Lakes area Rep Jim Lucas, of a high-end builder who will replace the wood siding on his older home. As part of the project, this gentleman will coat the structural walls with PROSOCO R-GUARD, before putting vinyl siding back on.
Then, he plans to monitor his heating and electrical bills for a year, and compare them to the previous year’s bills, using degree-days of heating and cooling supplied by his energy company. The comparison should give accurate data on savings that can be attributed to R-GUARD.
We’re not donating to this job. This is an actual paying customer.
This is the story I’ve been waiting for, where our claims get put to the test — not in the lab, but in the real world.
