Frequently Asked Questions

Q: What makes this S-type foam sealing strip suitable for casement windows?

A: The S-type profile is specifically designed to conform to the contours of casement window frames and sliding door tracks, creating a full-contact seal that blocks draughts, dust, and moisture more effectively than flat or round-profile strips.

Q: How do I install the 40M acoustic foam sealing strip?

A: Installation is straightforward and tool-free. Clean and dry the surface, measure the required length, cut the strip with scissors, and press the self-adhesive side firmly into place along the frame or gap. The foam compresses on closing to form a tight seal.

Q: Can this foam sealing strip be used outdoors or in wet areas?

A: Yes. The polyurethane foam is waterproof and weather-resistant, making it suitable for both indoor and outdoor applications including exterior window frames, garage doors, and areas exposed to rain or humidity.
