A garage is a place where people not only park their car but often also store tools, garden equipment, leisure equipment, sports accessories or children’s outdoor toys. Whether it is detached or integrated with the house, it requires appropriate protection. In this article, you will find the 7 key features of an energy-efficient garage door. Insulated sectional garage door panel Each sectional garage door consists of several panels. The most interesting product available in this regard is the 60mm-thick INNOVO panel by WIŚNIOWSKI, filled with the most effective thermal insulation material: CFC-free polyurethane foam. It stands out from all other solutions available on the market with its five-fold bending of the sheet at the hinge attachment point, which provides a strong connection between these two elements. Combined with its solid and closed structure, the INNOVO panel guarantees a long life for the door. This is an original design of the WIŚNIOWSKI brand, which has full control over panel production – from the purchase of steel from the steelworks to packing the finished garage door for shipment. In-house production ensures 100% repeatability, which translates into the highest quality. Low heat transfer coefficient for saving energy The lower the heat transfer coefficient for a product, the better. The value of this parameter is very low in the above-mentioned INNOVO panel, making it very effective in the UniTherm and PRIME sectional doors by WIŚNIOWSKI. The heat transfer coefficient for the INNOVO panel is U 0.33 W/m2K. For the entire garage door of 5m x 2.25m, the U coefficient is 0.95 W/m2K. This is one of the best results in the industry. Appropriate sealing Even the warmest garage door panel cannot fulfil its function without proper sealing. A very good proposal on the market is the door equipped with a set of seals: a double-lip top gasket, doublelip side gasket and a bottom seal equipped with three clips, thanks to which the door adheres better to the ground, isolating the garage interior from the outdoor conditions. For its products, WIŚNIOWSKI also offers an additional option, attractive from the point of view of thermal insulation – thermal and thermal-finishing seals. Safety A properly designed shape of garage door panels should prevent fingers from being smashed and determines the safety of users. Safe operation of the garage door is also ensured by its integrated protection against any uncontrolled movement in the event of a broken spring. The safety brake prevents the leaf from dropping in case of damage to the supporting cable. Efficient automation The current standard is a garage door opened with a remote control or an application. The integrated automatic drive is adjusted to the weight and size of the leaf and the specific door operation. Drives offered by WIŚNIOWSKI are made in cooperation with SOMFY, a global leader in the automation industry. One of the features is overload protection – the door that hits an obstacle will automatically open, protecting against smashing.
