Overhead sectional doors consist of multiple horizontal insulated panels that lift vertically and slide overhead. Ideal for industrial facilities, warehouses, garages, and loading docks, they provide excellent insulation, security, and smooth operation. The sectional design means no swing radius and full ceiling clearance when open.

Everything you need to know before buying
Overhead sectional doors are made of multiple horizontal insulated panels connected by hinges. They lift vertically and slide overhead, providing excellent insulation and no swing radius.
Sectional doors offer better insulation (PUF panels), aesthetic appeal, optional vision windows, and smoother operation. Roll-up doors are more compact but less insulated.
Our sectional doors achieve U-values of 0.5-1.0 W/m²K with 40-60mm PUF panels — excellent for cold storage, heated warehouses, and energy efficiency.
Yes! Vision panels (toughened glass) can be added to any panel for visibility, natural light, and safety. Multiple panel rows can have windows.
Yes, with thicker insulation (60-80mm) and proper sealing, sectional doors are widely used in cold storage and freezer applications down to -25°C.
Heavy-duty sectional doors last 15-25 years with regular maintenance. Springs and rollers may need replacement after 50,000 cycles.
