75055 SILL SEAL 5 1/2 IN X 50FT YELLOW

Overview

TVM Sill Seal (W507) is designed for foam gasket insulation applications at sill plate connections in residential and light construction settings.

Technical Features

• Polyethylene foam construction — provides a compressible, resilient barrier that conforms to irregular sill plate surfaces, reducing air and moisture infiltration at the foundation interface.
• 5½ in width — sized to match standard 2×6 sill plate framing, enabling full-coverage placement without trimming on common framing dimensions.
• ¼ in thickness — delivers a consistent gasket depth that fills minor surface irregularities between the sill plate and foundation without compressing structural bearing capacity.
• 50 ft roll format — continuous roll length reduces the number of seams required across a standard foundation perimeter, supporting uninterrupted coverage.
• Yellow color coding — allows for easy visual identification during inspection to confirm proper placement before framing proceeds.

Applications

• Sill plate insulation and air sealing between wood framing and concrete or masonry foundations
• Moisture and vapor barrier gasket at the mudsill in new residential construction
• Retrofit insulation under existing sill plates during energy improvement projects
