Expanding Sealant Tape is a high-performance sealing solution applied between PVC/Aluminum joinery and the subframe to ensure water, air, and wind tightness.
Thanks to its self-adhesive backing, it is easy to apply, and its pre-compressed structure, impregnated with special polymers, expands over time to perfectly fill gaps.
Resistant to external factors, IZOTEX Expanding Sealant Tape is designed to provide long-lasting and reliable sealing.
