The highlights of the aluminium composite system KOEMMERLING 76 AluClip Pro are its aluminium cover, its static functional properties, and its enhanced stability. This modern aluminium and PVC-U window fulfils the highest requirements for ultra modern, unlimited design potential and maximised thermal insulation.
KOEMMERLING 76 is a brand new generation of PVC-U windows that tick all the boxes. Not only do they automatically save energy, they also have perfectly elegant aesthetics.
Three aspects play an important role in window heat insulation: the profile's heat insulating properties, the insulating glass with edge sealant and the wall connections. In combination with an aluminium static profile (AluClip Pro), KOEMMERLING 76 can be installed without any steel reinforcement in the sash or frame.
The reinforcement chamber is foam-filled to improve the heat insulating effect. This innovative technology is called ProEnergyTec.
KOEMMERLING 76 can also integrate modern triple glazing or special functional glass in thicknesses of up to 48 mm. This prevents the loss of valuable heating energy, plus the large window panes allow the sun's warmth into the room. This is energy saving at its most simple and aesthetic.
