Doors exposed to adverse weather conditions can be certified with European standards (EN 1027 & EN 12208). This property guarantees that exterior doors are watertight . In this context, doors are subjected to torrential rain and high pressure to simulate severe thunderstorms.
During testing, a uniform jet of water is sprayed over the door or window, after which the air pressure is increased until the prescribed pressure, depending on the desired class, is reached.
This property is often combined with airtightness and wind resistance. Together these characteristics are called AWW (air-water-wind).
Thanks to their robust Metal+ structure, Heinen doors are resistant to deformation of the door leaf, which is usually subject to the elements and poses a particular risk of leakage.
Heinen has also paid special attention to the points that are usually weakest on exterior doors:
- on the upper part of the door leaf
- on the lower part of the door leaf
- at the connection point of the leaves (double doors)
