ProEnergyTec technology is a new technology for PVC-U profiles, with pre-assembled innovative thermal insulation materials. The reinforcement chamber is filled with ProEnergyTec foam and thus the thermal insulation increases.

Using special techniques, high torsional stiffness is provided to avoid the use of steel reinforcements inside the window. Instead, the booths are filled with ProEnergyTec foam, resulting in high heat insulation values.

In AluClip Pro systems the aluminum profile is connected with the composite. Aluminum undergoes the static operation so that it is not necessary to have steel reinforcement in the frames where the ProEnergyTec material can be placed, offering its beneficial advantages for extremely high thermal insulation.

The foam insulation material uses exclusively environmentally friendly agents and can be clearly separated from PVC for recycling purposes. This ensures that those using MARKAL products are also actively involved in protecting the environment.
