BOSS Polyurethane Foam

BOSS® 333 is a ready-to-use, multi-purpose, polyurethane foam that expands to three times its original volume when in contact with air. This volume expansion capability fills holes, cracks, and gaps more completely than standard caulks. The product also has excellent insulating properties and superb adhesion to virtually all building materials.

Features:

• Excellent stability with a high filling capacity.
• Freon-free.
• Good adhesion on all surfaces (except PE, PP, and PTFE).
• High thermal and acoustic insulation value.
• Excellent bonding properties.

Applications:

• All foam applications in static joints.
• Application of an acoustic baffle.
• Filling of cavities and sealing of all openings in roof constructions.
• Improving thermal insulation in cooling systems.
• Installation of doors and windows.

BOSS® 334 window & door, minimal-expanding gun foam is a one-component, ready-to-use polyurethane foam, formulated to seal the gaps around windows and door frames, and other rough openings.
