Polyurethanre foams
Polyurethane foams (PU foams) are suitable for filling, sealing and insulating gaps, joints and penetrations in construction, industry and maintenance. The foams expand when applied and harden into a durable structure that fills even uneven gaps and forms a tight insulating layer.
Etra's range includes installation foams for door and window installations and PU foams for sealing gaps, joints and penetrations. Polyurethane foam adheres well to many materials, such as concrete, wood, metal and plastic, and provides good thermal and sound insulation as well as an airtight result.
