Foamseal Liquid B3 — Case of 4

PARTEL FOAMSEAL LIQUID B3 is a moisture-curing, single-component polyurethane gun foam used to fill and insulate joints around windows, doors, and building penetrations.

What it does

Applied with a standard PU foam gun, the foam expands to fill irregular gaps and cures into a dimensionally stable, airtight thermal and acoustic insulator. It bonds to most construction substrates and can be cut, plastered, painted, or wallpapered after curing.

When and where to use it

• Window and door perimeter filling and insulation
• Sealing gaps and penetrations in the building envelope to stop air leakage
• Attic conversions, wall joints, HVAC and pipe penetrations
• Bonding insulation panels and rigid foam to substrate
