Aluminium Sliding Doors & Patios


The Corner Folding Door


The AMBIAL corner folding door can be fully opened inwards or outwards with the outer corner solution, offering you a panoramic view and flooding your rooms with natural light. This blurs the boundaries between indoors and outdoors.

An inner corner solution is available on request. 

Designed to be durable and easy to use, the AMBIAL supported folding door can incorporate up to 10-leaf configuration with a maximum height of 3m for a 12m wide opening. A flush fitting design provides visual harmony when open and closed, and the corner post profile is a minimal 93mm solution. Only one handle is required on the corner, and more comfort is provided with the option to open one side whilst keeping the other side closed.

All finishes have been designed with the greatest attention to detail to offer a harmonious appearance when open or closed. The frames are flush fitting with slim, well balanced profiles. Upper and lower rollers and fixings are covered to provide an uniform look, even when this system is open. Drainage is concealed to ensure a smooth, flush design.
