Standard features include durable soft-lift mechanisms and highly insulating thresholds made from glass fiber, enhancing stability and airtightness—key for coping with freeze-thaw cycles.

The screen frames perfectly match the exterior colour and finish of your door, creating a sleek, unified look.

These robust exterior door screens are built for smooth, long-lasting operation, enhancing both the functionality and aesthetic appeal of your energy-efficient lift-slide doors. Ideal for modern homes, our screens combine durability, style, and superior performance to protect your living space from insects while maintaining a clean, elegant appearance.

Our standard double low-e coating is a remarkable innovation that offers a range of benefits that make it the perfect solution for your home's windows. One of the critical advantages of our Low Carbon iPlus coating is its ability to regulate temperature. With this coating, at -10 degrees outside, the interior face of your window will be at around 21 degrees Celsius when the room temperature is 24 degrees. This means you'll avoid feeling cold drafts coming from your windows, allowing you to comfortably enjoy sitting on your sofa by the window. Additionally, during extremely hot summers, the intelligent protective coating will recognize the UV rays and reflect them more, creating comfortable natural cool inside your home. With a light transmission factor of 74%, windows with this low-e coating have the added benefit of opening up any room with natural, bright light. In addition, CO2 footprint of the 4mm-thick heat-insulating iplus glass pane is reduced to 5.8 kg CO2-eq/m, which means a reduction of more than 6 kg CO2-eq/m² compared to our previous 4mm ECLAZ ® low-e.
