SilverGlo is an R-11 rated insulation that will not mold over time. It is installed along all the foundation walls and between the subfloor joists. In most cases, the crawlspace will be encapsulated after the SilverGlo is installed. Typically, the Healthy Spaces installation team will use CleanSpace, a rugged liner, that is guaranteed against rips and tears for 25 years! The SilverGlo and CleanSpace duo transforms your crawlspace into more energy efficient space because it seals out the outside air and makes the crawlspace a conditioned space. Your HVAC system won't have to work as hard to create a temperate environment and your floors won't fluctuate in temperature!
