Depending on the customer’s requirements and architectural design, it is possible to install four door elements with movable or fixed leaves.

The most important parameter which defines the energy-saving level of the door is the overall heat transfer coefficient for the entire hoisted sliding door (Uw). The lower this coefficient is, the less heat the given house loses, which also means lower heating costs. Properly selected frame thickness and energy-saving, insulated triple glazing package allow to obtain outstanding heat transfer coefficient for the entire door, coming to Uw=1,00 W/m2K.
