When it comes to maximum heat insulation, only the best is good enough: The use of weather-resistant Alpine larch and plenty of technology lets NATURLINE 92 score points with maximum savings on heating costs – this is how to 'go green'. This takes the form of superior Uw insulation values ranging between 0,79 and 0,89 W/m²K. With thermally optimised glass spacers condensation on your window panes becomes a thing of the past (Gaulhofer Thermostop®). You not only benefit from being able to see out properly – the climate inside will improve as well.

Gaulhofer's Audiostop® technology featuring three circumferential seals ensures that noise, wind and driving rain can do no harm to either the house or its occupants. The glass joint is 100% tight thanks to hand-smoothed wet sealing with UV-resistant silicone: a special in-house development. Special seals additionally prevent condensation forming at the glass rebate – so keeping the NATURLINE 92 glass joint dry and protecting the sash timber from moisture (Gaulhofer Dampfstop® technology).

NATURELINE 92 still looks very elegant despite the greater installation depth of 92 mm. This is firstly due to the outstanding design of the frame, and secondly, to the fully concealed security hardware. This ensures nothing spoils the appearance of the wooden frame, which is set off perfectly with transparent coatings or varnishes. The concealed hardware doesn't just make the window look neater on the inside – it also increases the bearing capacity of the frame.
