The special fibre glass reinforced uPVC (powerdur) inside the profile provides the stability requirements, eliminating the need for any additional steel reinforcements. Using powerdur® instead of steel in the profiles considerably improves their insulating properties.

Windows with powerdur and bonding inside are up to 20% lighter than conventional windows and yet even more stable – saving fuel during transportation and relieving strain on the environment.

Window sashes glued to the pane increase the window's impermeability, improve thermal insulation, and enhance their stability.

The adhesive provides an extra strong bond all the way round the glass pane and sash: the best way to prevent the sash from being pried open.

The innovative technology foam inside allows for sensational thermal insulation values! The central interior chambers of the window frame and sash are filled completely with polyurethane foam after welding. Polyurethane is an industry-proven insulating material that aluplast employs successfully in its windows.

The benefits of polyurethane

The outstanding thermal insulation characteristics of polyurethane are the reason why this material is employed in refrigerators and freezers, flooring, and other sealants and insulation. When recycling the windows, the polyurethane foam can be separated completely from the other materials and fully recycled.
