Sectional doors open vertically, creating free space in front of and behind the door. The door sections are stored flat underneath the ceiling, vertically above the opening or along the roof. Series 50 sectional doors made of steel, a combination of steel/aluminium or aluminium, will convince you with their unique programme range, top door design and certified security. Compact sectional doors stack the individual sections vertically, directly behind the lintel. The small distance back is particularly advantageous for halls with dome lights, glass roofs or glass facades.
Doors occasionally take up a large portion of commercial buildings. They thus offer substantial energy savings potential – for more information about the amortisation and retrofitting see the Hörmann energy savings compass.
