Tu-Tuf #4 Vapor Barrier White
Tu-Tuf #4 Vapor Barrier White, provides a barrier against air and moisture penetration. Wrap it completely around the house including ceilings, and around walls right up to the windows and doors. Foundations are wrapped around the outside perimeter from the base to ground level and the Tu-Tuff is laid under the concrete flooring making the problems of moisture penetration and dampness absolutely minimal. Because Tu-Tuf is cross laminated it has 3.6 times the tensile strength and 6.4 times the puncture resistance of the standard 4 mil low density poly. It is also pinhole free, an impossibility with typical barriers.
Because Tu Tuff stops moisture and wind chill, the structure is warmer, drier and easier to heat with less energy. Tu-Tuf is handy, above & below ground. In General – Tu-Tuf should be run completely around your structure, including walls & ceiling. The two types (XF & #4) have almost identical vapor barrier properties. Interior Walls – Tu-Tuff is generally to be placed over the warmer, more moist side of your insulation material (usually between interior insulation & interior walls). Foundations & Slabs – Wrap Tu-Tuf around your outside perimeter from base to ground level. Place Tu-Tuf under concrete flooring.
