For Passivhaus levels of performance


For Passivhaus levels of performance


proEnergyTec was specifically developed to enabled Passivhaus levels of performance on a 76mm profile platform for KÖMMERLING. Up to this development, a profile platform of 88mm had to be used to reach the Uw value of 0.80 W/(m2k), which required more material and a less than slimline sightline. These pre-foamed profiles have proven to offer far better levels of performance than post extrusion manual profile inserts.

The development of proEnergyTec has also been done with the environment in mind, as they harness an eco-friendly agent, while they can be processed in the usual manner to a typical PVCu profile. Because the pre-foamed profile is free of greenhouse gases (HFC’s), this means that these proEnergyTec profiles are also 100% recyclable.

Providing Passivhaus levels of performance with sustainability.

Without proEnergyTec, Passivhaus levels of performance cannot be achieved in our hybrid windows and so it’s a fundamentally important technology for us. With KÖMMERLING as our profile partner it’s reassuring to know that they are ahead of the game when it comes PVCu profile and material technologies.
