Penosil 198 Airtight Elastic Low Pressure Expanding Foam Gun Grade
PENOSIL 198 Window & Door Elastic Gunfoam is a pale green one-component polyurethane gun foam for installation works and sealing of pressure sensitive, movable joints and penetrations. Use for sealing windows and doors and other narrow pressure sensitive and moveable joints. The foam is flexible when cured allowing for movement. Also use for insulating internal ventilation devices and pipe penetration. It enhances thermal and sound insulation and for reducing the impact of thermal bridges.
Shake can vigorously before use.
Fill the joints to approximately 70%. For larger joints apply in layers moistening slightly between layers, see TDS for details.
