The best window in its class.

energeto® is a window without any metallic thermal bridges. All versions and construction depths in this range record impressive insulation figures, helping to actively reduce CO2, cut heating costs and, as a result, protect the environment.

The steel reinforcements fitted in conventional windows are the weakest point in terms of thermal properties. Thanks to the “bonding inside” and “powderdur inside” technologies, we have made a huge contribution to energy efficiency.
