Characterised by an installation depth of 94 mm, the FUSIONLINE 94 frame made of high-grade timber has already been given great heat-insulating properties by nature itself. This is coupled with expert workmanship and Gaulhofer Thermostop® technology featuring innovative, highly insulating glass spacers, in addition to Thermostop®plus, which prevents condensation forming on the window panes. Depending on the design, this results in outstanding Uw insulation values of 0,84 and 1,19 W/m²K.

Gaulhofer has also developed technology to deal with noise and draughts. Thanks to three circumferential seals, Gaulhofer Audiostop® ensures that noise outside doesn't stand a chance of getting in – and nor do wind or driving rain. Hand-smoothed wet sealing combined with Gaulhofer's UV-resistant silicone guarantees the glass joint will remain 100% tight. Special seals additionally prevent condensation forming at the glass rebate – so keeping the FUSIONLINE 94 glass joint dry and protecting the sash timber from moisture (Gaulhofer Dampfstop® technology).

FUSIONLINE 94 SOFT offers a semi-rebated aluminium shell without hard corners and edges - this creates a softer look and a rounded overall impression on the outside.

FUSIONLINE 94 PURE impresses lovers of design with its rebated aluminium shells and clean lines.

FUSIONLINE 94 PLANE on the other hand boasts flush-mounted aluminium shells and a simple, purist look.
