DUTEMÄNN GLIDE-S DOOR - AS INDIVIDUAL AS YOU ARE Not only will the Dutemänn Glide-S sliding door deliver more light and space compared to conventional patio doors, you can have it custom-designed to be as individual as you are. Up to 200 RAL colours and shades to choose from As well as a choice of standard colours such as Gloss White, Anthracite and Black the Dutemänn Glide-S is available in up to 200 RAL colours and shades. RAL is a European colour matching system used by designers and architects to help them achieve a bespoke look. Marine finishes Salt water and wind from the sea or lochs can cause wear and tear. EKCO offers a marine-standard finish for our Dutemänn Glide-S sliding door which is perfect for homeowners who live in coastal towns.
