Product Overview
Two panels that meet in the middle and swing open inward or outward give you full-width access to a garden, terrace, or adjoining room. The 80mm profiles contain 45mm thermal breaks, which contribute to high thermal efficiency.
When the doors close, the central overlap is only 110mm, so you get maximum glass and minimal obstruction. They’re PAS 24 certified, which covers enhanced security standards for doors. Aluminium construction means they won’t warp, rot, or need repainting.
