Energy efficient front door
Thermally insulated front doors for a better energy balance.
Energy efficiency is becoming increasingly important, and for good reason. That's why we have always placed great emphasis on multiple sealing levels when developing our thermally insulated doors. Only a truly airtight door reliably protects you from cold and noise, reduces your heating costs in winter and promotes energy-efficient living through intelligent construction.
In-house climate chamber
Resistance to cold temperatures and extreme heat: both of these capabilities are rightly expected of Groke doors. This means that the installed materials must withstand icy temperatures and blazing heat in the Groke climate chamber. Thermographic tests create surface temperatures of -30°C to +100°C.
Thermal insulation for front doors
High thermal insulation leads to lower energy costs and is required by law. The thermally insulated Groke aluminum front door is characterized by a low Ud value, which minimizes heat and energy loss. As standard, the Groke front door offers excellent thermal insulation thanks to the optimally thermally insulated 3-chamber profile system Groketherm "GT 90" Symphonie and Arcade with additional insulation in the insulation zone and thus meets the requirements of the energy saving regulations.
Thermal protection through door filling covering the sash
With the filling covering the sash, the door filling covers the entire outer and inner sash frame. In addition to the visual advantages, fillings covering the sash on both sides offer a high level of thermal protection.
Ud values up to 0.71 W/(m2K) - Without glazing
Triple glazing
Groke triple glazing offers not only increased security but also excellent thermal insulation for your front door.
Multiple sealing levels
The three sealing levels - a four-sided central and inner seal and a three-sided outer seal - are mitred and glued without interruption, thereby guaranteeing a high level of thermal insulation.
