INSULATED SECTIONAL OVERHEAD DOORS
Insulated sectional doors
are designed to meet the needs of modern Industrial, Warehouse and Commercial “Hi-Tech’ Buildings. Incorporated into the advanced design are a variety of features such as insulation weather sealing, glazing and ease of operation, which present a significant development to the more traditional types of door.

Operation of the door manually is effortless either by means to pull chain or gear reduction hoist. Power operation is also available and is increasingly in demand. Where frequent use is anticipated the unit can be linked with various automatic control options.

Each door is “made to measure” to suit the individual requirements of the Customer and to take advantage of the headroom available within the building strcuture.

Our full U.K. Installation facility is backed up with a comprehensive after sales contract maintenance service to ensure your door is kept in good condition.

Specification - Door Panel
The door panel is constructed from 0.7mm or 0.5mm galvanised steel sheets bonded together with C.F.C free polyurethane foam with integral thermal breaks to provide a 'U' value of 0.45w/m2'C. The combined effect of the panel insulation properties together with the effect of the thermal bridges at the panel to panel joints results in an overall 'U' value of 0.60 w/m2'C. This exceeds building regulation requirements. All panels are fitted with fully punched galvanised end caps.

Roller Carriers and Hinges
Adjustable roller carriers are fitted to the ends of each panel incorporating nylon rollers to provide smooth/quiet operation. Intermediate hinges are fitted typically at 1000mm centres. For wider doors an additional strengthening omega strut is provided to ensure the panels remain rigid.

Counterbalance Spring Assembly
All springs are calculated to suit the height of each door, which are fitted to a 1" solid steel shaft and secured to the opening structure via bearing plates. The number of springs and plates depend on the size of door cable drums mounted at each end of the shafts carrying the galvanised steel cables which lift the door. All Multi Industrial Doors S.O.H.D. are fitted with cable and spring break devices as standard.

Tracks
The tracks are formed from galvanised steel and supplied with a continuous angle for fixing to the opening.

SealsFlexible black rubber seals are fitted to all four sides. Top seal compresses against the lintel and bottom seal has 3 points of contact with threshold. We recommend the threshold is finished with a small incline away from the opening.

Furniture
As standard all manual doors come with footstep handle and spring loaded shoot bolt fitted to the right hand side of the door (viewed from inside).
