The doors stack tightly to one side, creating a completely unobstructed view, enabling your clients to make the most of the available space. Our doors comply with Building Regulations Document L and have multipoint lock mechanisms for additional security. The profiles feature a polyamide thermal break that boosts the thermal performance of the door, while high quality gaskets keep the bad weather out.
