UPVC Doors will never flake, peel rust or rot and are relatively maintenance free to keep the ongoing work low going forward.

Designed To Retain Heat

The glass in our standard UPVC doors is 28mm thick, double glazed units for low-e energy ratings and thermal efficiency.

Built To Last

Glazing beads are fitted internally for extra security and our doors use a PAS 24 security package.
