Glazing tape designed for a weatherproof, high-tack bond on window and door frames. Homeowners gain confidence from draught-free, watertight windows and fewer repair calls. Is Generic Double-Sided Foam Tape the practical sealing solution for long-term outdoor use?

⚡ At a Glance
  • Sealing Performance: High-tack, weatherproof bond on glass and frame surfaces
  • Best for: Residential, commercial and industrial glazing applications, including UPVC windows and skylights
  • Not ideal for: Heavy mechanical load-bearing or structural bonding applications

Closed-cell Polyolefin foam creates a durable, UV-resistant seal suitable for outdoor glazing. High-tack adhesion and a non-tear release liner allow quick, tidy installation without sealants.


Watertight seals – with closed-cell Polyolefin foam

Closed-cell Polyolefin foam is composed of sealed cells that resist moisture and limit air permeability, helping maintain an airtight joint. UV-resistant chemistry helps the foam retain its properties in outdoor conditions.

Prevents leaks and draughts around glazing units when applied to compatible frames, giving a reliable weatherproof seal.

Quick, tidy installation – with a non-tear film release liner and high-tack adhesive

A non-tear film release liner enables precise placement during fitting, while the high-tack adhesive creates immediate bonding to both glass and frame surfaces. The adhesive achieves initial hold without curing time.

Peel, stick and press for an immediate, clean seal that avoids messy sealants and reduces installation time.

Thermal and acoustic benefits – thanks to closed-cell foam structure

The closed-cell structure provides thermal resistance and dampens sound transmission through gaps in glazing. The foam acts as an insulating barrier between glass and frame materials.

Helps reduce heat loss and cut outside noise, improving comfort around windows and doors.
