Why Choose Aluminium Retention Trims

Aluminium trims are the preferred choice for architects and roof specialists who value precision and longevity. They hold roofing membranes firmly in place, preventing wind lift and maintaining a watertight seal. Unlike plastic options, aluminium trims stay rigid and retain their finish for years.

The powder coated finish ensures colour consistency with other external fittings such as copings, fascias and gutters – creating a seamless architectural appearance.
