Door Industry Journal - Summer 2018

Also online at: www.dijonline.co.uk Industrial Doors & Shutters Large industrial doors are often a weak point when it comes to insulation and can lead to a significant increase in energy bills. This effect is magnified as the number of doors increases, making energy-efficient operation in industrial buildings a significant economic factor. In addition, CO2 emissions are reduced. The new ISO 80 Door from Alpha Deuren features an 80 mm door panel - twice the thickness of the panel used for the ISO 40, which is the company’s most popular product. With a U-value of 0.25 W/m 2 K, the panel thickness of the ISO 80 guarantees a heat transfer coefficient that is reduced by more than half in relation to the Dutch company’s all-round ISO 40 door (U-value: 0.52 W/m 2 K). Furthermore, the higher quality seals between the door panels mean that this new door optimally closes the opening. The rubber seals were improved both functionally and thermally to achieve this: Newly developed top rubbers ensure the best possible seal between the lintel and the ISO 80 door and two bottom rubbers achieve an even better seal to the floor. The three side rubbers offer further economic benefits by optimising insulation in this area. The ISO 80 door satisfies the requirements for wind resistance class 4 and can withstand wind speeds of up to 150 km/h. The new sectional door from Alpha Deuren is available in sizes up to 8m wide x 6m high (maximum surface 42m 2 ). The different window styles ensure both optimum light ingress and specifiers can create individual and attractive designs in combination with the elegant Microline panel profile.
