Timber-aluminium windows

For centuries, windows have been manufactured exclusively from timber - each wooden window was a unique master piece - made by hand, exactly adapted to the fitting location and its function. Even if Internorm quality wooden windows nowadays are manufactured partly by a mechanised process, craftsmanship is still involved and thus upgrades the timber-aluminium window.

Thus, the processed timber is subject to strict criteria at Internorm. Already when the wood is cut at the sawmill, only the best and nicest pieces of the trunk are used to achieve an even grain pattern and to emphasise the timber characteristics; all with the aim to achieve the most harmonious and individual composite window. 

Timber does not only provide naturalness and cosiness as material. Characteristics such as low thermal conductivity as well as high strength and stability fulfil even high static requirements of a composite window. The composite of aluminium, thermal foam and timber in composite windows features a weather-resistant aluminium clad on the outside and a warm timber surface on the inside of the timber-aluminium window. This results a composite window with perfect insulation properties with narrow construction depth and many possibilities of colour design.

Internorm timber-aluminium windows can be perfectly combined with UPVC-aluminium windows in all four design styles. 

Timber windows are unparalleled in their naturalness and cosiness. The aluminium clad on the outside protects the timber from weathering. Special foam situated between the timber and aluminium additionally ensures perfect thermal insulation and excellent U-values of the composite windows.  

Next to the classic timber types such as spruce and larch, we can also offer you oak, ash and walnut. These are available in different colours. Thus, your composite windows can perfectly match your interior design, your floors and your interior doors.
