Insulated sectional garage doors in Llantwit Major

Choosing an insulated sectional door for a home in Llantwit Major

What thickness should you pick?

Most domestic sectional doors use panels of about 40 to 42 mm. Doors sold as thermally broken use thicker panels, often around 67 mm, with a break between the inner and outer skins so cold is not conducted straight through. The thicker option costs more and needs a little more headroom, so it makes most sense on integral or heated garages.

Will an insulated door help an integral garage?

Where a garage shares walls with the house, a colder garage means colder shared walls and rooms above. An insulated door will not turn a garage into a habitable room, but it does take the edge off, especially paired with a draught-sealed door between the house and the garage.
