Sectional doors , whilst relatively new on the market, are becoming increasingly popular for the many advantages they have over traditional garage doors. For example, they are vertically opening and thus allow parking right up to the door and with frames fitted behind the reveals allow full structural opening drive through width and height. They are fully draft proof on all four sides of the door and are available in three specifications :- single-skin non insulated, double-skinned with 20mm of insulation and double-skinned with 42mm of insulation, the latter being ideal for integral garages where a noticeable improvement in comfort levels of adjoining and overhead rooms is apparent. There is also a full range of colours and wood effect doors available in most specifications.For those preferring natural timber there is a range of Nordic Pine and Hemlock doors. Sectional doors can be automated with the standard range of operators.
