75035 SILL SEAL 3-1/2INX50FT

Overview The TVM 75035 Sill Seal (W506) is designed for sill plate insulation and air sealing applications between foundation walls and wood framing in residential and light commercial construction. Specification Value MPN W506 Brand TVM Material Polyethylene Foam Insulation Type Foam Gasket Roll Length 50 ft Width 3-1/2 in Thickness 1/4 in Color Yellow Technical Features Polyethylene foam construction — provides a compressible, moisture-resistant barrier that conforms to irregular concrete and masonry surfaces to reduce air infiltration. Foam gasket insulation type — creates a continuous thermal break between the sill plate and foundation, reducing heat loss at the rim joist assembly. 3-1/2 in width — sized to align with standard 2x4 framing lumber sill plates for straightforward, precise placement without trimming. 50 ft roll length — provides continuous coverage across typical foundation perimeters, minimizing seam locations and potential air leakage points. 1/4 in thickness — offers a low-profile, compressible profile that accommodates minor surface irregularities without interfering with framing alignment. Yellow color coding — enables quick visual confirmation of correct placement and coverage during framing inspection. Applications Sill plate insulation between poured concrete or block foundations and wood framing members. Air sealing at the base of exterior wall assemblies to reduce drafts and energy loss. Moisture vapor buffer between concrete foundations and wood sill plates in new residential construction. Retrofit insulation upgrades where existing sill plate connections lack a thermal break.
