European Passive House Windows


The U-PVC series is reinforced with galvanized steel to increase structural support and increase the frame’s energy performance. It combines Stabilizer and Titanium Dioxide to protect the window from harsh weather conditions including pollution and UV rays. The U-PVC windows are able to withstand temperatures up to 180 ℉.

This series of Intus window employs a corner welding process in order to ensure that the frame is welded into a single structure. This method restricts the flow of water through the welded joint. In addition, the Eforte series has triple seals of EPDM rubber gaskets are placed around the sash and the frame to efficiently seal the gap.

These windows are equipped with multi-point locking hardware systems, which ensures efficiency and safety. It also allows the windows to be securely closed and tight, thus reducing any noise disturbance.
