The uPVC windows in the ENERGYLINE 85 series offer impressive insulation values ranging from 0,66 to 1,2 W/m²K, with the foamed ENERGYLINE PLUS profile variant even attaining the peak value of 0,72 W/m²K. This performance spectrum depends on the glazing used in each case, but above all on the construction of the shutter frame and its reinforcement. The high thermal insulation glass spacers of Gaulhofer Thermostop® technology also guarantees that condensation doesn't stand a chance on the inside of the glass. Treat you and your family to an extra serving of home comforts – now and for years to come.

This uPVC window flexes its muscles while however entirely doing without steel reinforcement, which is characterised by thermally unfavourable properties. Instead, high-stability PowerDur glass-fibre reinforcement ensures that the uPVC windows from ENERGYLINE 85 have never been so stable – thanks to circumferential reinforcement and perfect screwed connections at every fixed point. Bonding of the sash in the glass using PowerBond adhesive all round makes the sash particularly torsion-resistant, in particular a key factor for balcony doors or large windows where requirements in terms of building physics are concerned.

Windows also fulfil an extremely important function: ensuring sound insulation. Gaulhofer's Audiostop® technology, based on three circumferential seals, promises relief from noise at night, so significantly enhancing your quality of life. But your windows should also appeal to the eye. A wide variety of designs is thus ensured by Gaulhofer's extensive programme of decors featuring Cool-Color technology. Put nature into the home with six imitation wood decors – they look just like wood and at first glance can't be distinguished from the real thing.
