Efficient performance

Its innovative thermal break technology means the door meets Part L thermal efficiency requirements of Building Regulations with standard 28mm double glazing.

It’s also fabricator-friendly with a direct glazed fixed light, eliminating the need for a fixed dummy sash, reducing fabrication time and improving manufacturing efficiencies. And thanks to its pre-gasketed, knock-in beads, installation is quick and straightforward, whilst providing a neat, high-end finish on the gasket line.


Our range of threshold options can meet various access needs. Some can be set into the floor, for an almost seamless transition. There are options designed for wheelchair access, and for exposed locations deeper thresholds channel water away from your home.
