A high-performance replacement threshold gasket seal designed to restore or upgrade worn, damaged or missing seals on uPVC doors and windows. Engineered to deliver a tighter, more efficient seal, it helps reduce draughts, wind whistles, water ingress and heat loss while improving overall energy efficiency.
Ideal for both repair and refurbishment projects, the T3 threshold gasket provides excellent compression recovery and long-lasting durability in both residential and commercial glazing applications.
