Self-Expanding Sealant Tape

Self-Expanding Sealant Tape is a pre-compressed polyurethane foam sealing tape designed to provide reliable airtight and watertight protection in metal roofing systems. After installation, the tape gradually expands to fill uneven gaps, roof joints, and profile transitions.

The expanding foam structure helps block wind-driven rain, snow, dust, insects, and moisture infiltration while maintaining long-term flexibility and sealing performance. Its durable weather-resistant material adapts to irregular roof surfaces and improves overall roofing system protection.

This sealing tape is commonly used at ridges, valleys, panel overlaps, flashing connections, and roof transitions where additional sealing and weather protection are required. Compatible with metal tiles, standing seam systems, and other metal roofing profiles.
