SVS® is an underlayment in a class by itself. It has been tested under various conditions for its permeability and effectiveness for protecting hardwood floors from subfloor moisture. It has been recognized and given accolades by various hardwood industry associations including the NWFA and the Radiant Heat Association.
SVS® is made of 6 mil. wet-strength paper and has a baked-on silicone coating. It won’t easily tear apart during installation like red rosin, craft paper or wax papers.
SVS® has two sides, one matte surface, the other a smooth surface which allows installers to slide wood planks easily. This also provides the perfect surface to have clear visible chalk lines so an installer’s work can remain accurate. It also won’t leave a black residue on hands or walls and keeps the surrounding work areas clean.
Radiant Panel Association lab tests have confirmed that SVS® is suitable for use on radiant heated floors. They found that there was “no measurable resistance to heat transfer with the product. No odors were released from Silicone Vapor Shield® when heated from 90F to 100F.”
SVS® is available in 4 sizes; 200, 400, 800 and 1000 square foot rolls. Its easily applied to any area regardless of size or location.
