AC20-FL Vilstal window

AC20 FL Wood-aluminium window


The AC 20 FL wood aluminium window impresses architects worldwide with its appealing and clear appearance on the outside. Especially in modern architecture, the flush, linear geometry of the aluminium frames complements the design of your building envelope.

The elegant and timeless design can be used in a variety of opening types (tilt-turn, top hung, casement, fixed or hopper windows) and window constructions ( segmental or pointed arches). With the help of innovative special fittings, even casement windows with heights of up to 3 metres and sashes with weights of up to 300 kg can be realised. Large window surfaces flood your rooms with light and warmth from the sun, creating a healthy atmosphere of well being.

Fully concealed hardware? This is no problem with our flush window system. The hardware disappears completely into the window frame and can also be used with particularly heavy window sashes. The interplay of the energy-efficient timber frame and the weather-resistant aluminium cladding on the outside fulfils the Zeitgeist of sustainable building 101 and allows our AC 20 FL system to take on a key role in the future building sector.

Discover the possibilities of a sustainable building envelope all over again and feel the quality in the craftsmanship of FT Vilstal windows.
