Alutech Sectional Garage Door Insulation

Sectional Door Panels - Strength and Warmth

Engineered to withstand extremes of heat, cold, wind and rain, Alutech sectional garage doors are built to cope with the worst the great British weather has to throw at them.

    Sectional garage doors are the superior option for insulation, weather resistance and impact protection. Insulation values are rated on the “U” value scale and  independent tests undertaken at the Rosenheim institute in Germany confirm that Alutech sectional garage door scored an outstanding U value of 1,35 W/(m2K) .

    This means an Alutech sectional garage door will keep your home warmer and maximise your energy efficiency. Whenever warmth and energy efficiency is a priority a sectional garage door is the only sensible choice and as one of the best insulated sectional doors available in the UK Alutech doors are a great investment.     This performance is achieved due to the unique sealing system developed by Alutech. All roller brackets are fully adjustable by the installer thus ensuring the door makes complete contact with the door seals, eliminating any drafts and minimising heat loss.

The side and top seals fully enclose the edge of the door frame preventing empty spaces which are known as “cold breaks”. This design is a standard feature with Alutech doors whereas some competitors charge extra to add the same sort of cold break protection. The bottom seal is a multi-chamber heavy duty rubber moulding formed from aircraft quality rubber polymer. The multiple air pockets within the seal are unique to Alutech and allow the seal to be more robust and to compress with greater force, this ensures maximum insulation as well as protection from water ingress and drafts. Alutech sectional garage door panels are formed with high density polyurethane insulation foam sandwiched between a dual zinc coated steel outer skin. This design provides incredible strength and rigidity allowing the fully installed door to achieve up to class 4 wind load resistance. The 40mm sandwich panel also provides equivalent thermal insulation to a 550mm brick wall.
