WKRĘT-MET PMW SMART 750ml vähän laajeneva asennusvaahto ja pilliapplikaattori

The WKRĘT-MET PMW SMART is a professional single-component polyurethane mounting foam designed for efficient and precise installation. With a 750ml can and straw applicator, it delivers up to 45 liters of low-expansion foam, ideal for filling gaps, insulating windows and doors, and bonding building materials. Its controlled expansion minimizes stress on frames while ensuring a durable seal.

Advantages

Low expansion reduces the risk of deformation, excellent adhesion to wood, concrete, brick, metal, and PVC, and quick skin formation (10-15 minutes) for efficient workflow. The foam provides thermal insulation (λ=0.036 W/(m·K)) and acoustic insulation up to 60 dB.
