The optimum Uw value of 0,74 W/m²K offered by the FUSIONLINE 108 wood-aluminium window lets you enjoy maximum protection from cold winter weather (other models to 0.89 W/m²K). Performance fit for a passive house means you minimise your heating costs as well. Other high-tech features of this model are bound to delight: Gaulhofer Thermostop® technology with high thermal insulation glass spacers and Thermostop®plus technology, which banishes condensation on the inside of the glass. Despite the mighty design, the elegant profile view for large areas of glazing will appeal to the eye while offering maximum stability.

The noisy outside world and draughts don't stand a chance here. The FUSIONLINE 108 wood-aluminium window featuring Gaulhofer Audiostop® with three circumferential seals ensures a whisper-quiet interior so you can enjoy a good night's sleep without being bothered by noise. Hand-smoothed wet sealing combined with Gaulhofer's UV-resistant silicone guarantees the glass joint will remain 100% tight – gales or heavy rain just cannot get in. Special seals at the glass rebate keep the FUSIONLINE 108 glass joint dry, so protecting the sash timber from moisture – you too should rely on Gaulhofer's revolutionary Dampfstop® technology.

All Gaulhofer wood-aluminium windows from the FUSIONLINE 108 range are characterised by fully concealed hardware, which makes for a slimline design, clean lines and an unbroken profile to the wood.
