The future of the window

energeto® is a window without the thermal bridge “steel reinforcement”. The system has excellent thermal insulation values in all versions and profile depths and by this means contributes actively to the reduction of CO2, saves heating costs and consequently protects the environment.

What distinguishes energeto® from a conventional window?

The steel reinforcement inside conventional window frames is the weak point in terms of thermal insulation. As the possibilities to optimize insulation by means of profile depth and number of hollow chambers have already been pushed to the limit, an alternative to the steel reinforcement needed to be found. With the aluplast technologies "bonding inside" and "powerdur inside" we developed the perfect solution. "foam inside" complements these technologies for even better insulation values.

bonding inside + powerdur inside = energeto®

bonding inside

bonding inside

Bonded glass units in the glazing rebate for all window and door sash sizes prevent the thermal bridge that is typical for conventional windows.

powerdur inside

powerdur inside

Fibre-reinforced powerdur strips replace the steel reinforcement in the sash and frame. These powerdur strips have been developed jointly with BASF.

foam inside

The ultimate perfection: foam inside

energeto® finds its perfection in another process technology: foam inside. By filling the profile chambers with special polyurethane foam, outstanding insulation values can be realized.


Through innovative conception: same size, more light!
