Large and oversized sectional garage doors

When is a door oversized?

Anything taller than about 2.3 metres or wider than a typical double, roughly 5 metres, usually moves into larger spring and track specifications. Motorhome garages often need heights of 3 metres or more.

Do tall doors need more headroom?

A tall door needs a correspondingly long horizontal track and a suitable ceiling or roof structure to fix it to. Barns and garages with pitched roofs often have room for a high-lift or vertical-lift track that keeps the door higher up the roof slope.

What about oak-framed and timber buildings?

Doors can be fixed to timber frames, but the fixings and any packers have to suit the frame, and green oak moves as it dries. The survey checks the frame and the fixing positions.

Is a domestic operator enough?

Not always. Larger, heavier doors need an operator rated for the size, and very large doors may use a shaft-mounted operator instead of a ceiling rail.

Can large doors be insulated and glazed?

Yes. Most large doors use insulated panels, and window rows or vision panels can be added to bring light into a long garage.

How are lead times affected?

Non-standard sizes are made to order, so lead times can run longer than for common domestic sizes. The quote shows the expected lead time.

What options are there?

• High-lift tracksUse roof height so the door parks higher.
• Heavier springsSpring sets sized to the larger door weight.
• Vision rowsWindows across one section.
• Shaft or rail operatorSpecified to the door size.
