Slimline 38 aluminium door system

SL 38 is a well-insulated aluminium window and door system that opens both inward and outwards. This steel looking door is perfect for both modern architecture and the changing of old steel-frames, keeping the same look yet dramatically improving thermal performance.

The SL 38 system is available in 3 different styles which are Classic, Cubic and Ferro to match any architectural demands of any building. We are able to provide this system with double or triple glazing without losing the benefit of the great ultra-slim look.
