AC20-FL Vilstal window

AC20 FL Wood-aluminium window


The AC20 FL can be provided in a variety of styles: tilt/turn, top-hung, casement, fixed or hopper, with the option of round, segmental or pointed arches.

Using specialist hardware, casement windows up to 3m in height and weighing 300kgs can be achieved. If concealed hinges are required, our flush window system conceals the hinges completely out of sight when closed and can be used on particularly heavy sashes.

This combination of modern technology and visually astounding aesthetics, combining traditional timber frames with seamless aluminium exterior facings, creates energy-efficient and weather-resistant windows that are integral to the future of sustainable construction.

Let us show you how the quality of FT-Vilstal joinery can blend in with any type of building envelope and internal colour scheme, whether traditional or modern or a combination of both.

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