Cleanspace is a vapor barrier engineered for energy efficiency and resiliency that actually brightens your crawlspace at the same time. Imagine an antimicrobial pool liner that would seal the entire crawlspace and lock out the fluctuating heat cycles of outside air, allowing your heating and air conditioning system to operate cleaner, better, and for less money. It’s also guaranteed against rips, cracks, tears, and other strains for 25 years! It’s a great product that can really transform a crawlspace into a healthy space.
