TP450
Compriband Timber Max

TP450 is a soft and flexible open cell polyurethane foam, impregnated with an acrylic based, UV stabilised resin. It provides a weather tight seal against the most severe combinations of wind & rain.

Usage/Purpose

TP450 provides a weather tight seal against the most severe combinations of wind and rain, with particular suitability for sealing the head and sills of windows installed in timber frame construction and can accommodate up to 37 mm of differential movement within a max. 50 mm wide joint. Extensively tested with BBA accreditation, TP450 has a proven reputation across both the UK and Europe.

 

  • Minimum 450 Pa weather resistance, 600 Pa with the three smaller sizes, to DIN EN 1027
  • Accommodates up to 37 mm of joint movement within a maximum 50 mm wide gap
  • Weather seal for wind-driven rain but breathable for vapour diffusion
  • Can accommodate differential movement on timber frame construction up to 5 storeys
  • Seals effectively – no remedial visits or wet sealants
  • Continually expands and contracts to accommodate movement whilst still sealing the joints
  • Long life expectancy

    Usage Guidelines

    Tape Specification
