AC20 AP Wood-aluminium window

unique. MODERN.

Our latest AC20 AP system sets new standards in design aesthetics and can easily be configured to a client’s preferences.

With a width of only 50mm this aluminium-faced timber window still meets the structural performance requirements of the building code.  Less frame thickness allows greater glazing areas, creating a brighter interior environment for the same given size of a conventional frame.

The aluminium facings on the outside of frames and sashes are seamless at corners, using fully welded joints, creating an uninterrupted and unblemished appearance to the entire external surface.

Fully concealed hinges are a key feature of the AC20 AP system, including heavy window sashes.

The hidden profiles in the aluminium facings are designed to divert water down and out, ensuring that rain never penetrates far enough to reach the timber frame. This combination of modern technology and visually appealing design, combined with traditional timber frames, combine to create energy-efficient and weather-resistant windows that are the key to the future of sustainable construction.

Visually attractive from both sides: a design innovation to satisfy current trends.

The AC20 AP system is the innovative answer to the latest architectural trends which aim to achieve a high level of aesthetics and comfort living through maximum glazing in the building.

With its slim elevation width of 98 mm and the integrated sash profile, AC20 AP meets exactly these requirements while maintaining excellent structural stability.
