PREFA façade sidings are classic elements of both traditional and modern façade design. These high-grade aluminium façade panels can be installed vertically, horizontally or even diagonally, and take the form of a non-bearing, rear-ventilated façade. This means that there is space for air to circulate between the supporting structure and the PREFA aluminium façade.

The benefits of PREFA sidings

Weather-resistant and corrosion-free façade system

with a 40-year material guarantee – no time-consuming paint top-ups required

Design options with PREFA sidings

With the PREFA siding façade, you can put together your own personalised façade solution. Choose from different widths: 138 mm, 200 mm, 300 mm, 400 mm, 500 mm or 600 mm, and a range of surface textures: smooth, stucco or lined. With a range of 21 colours at your disposal, you can choose the perfect shade for your PREFA sidings. (Please note the standard colours for the various widths. For more information, please refer to the colour chart.) And the possibilities don't stop there: you can choose from different lengths (500 to 6,200 mm) and decide whether you want standard or shadow gaps. By choosing how you want to combine all these different options, you can create your own personalised house façade. 

The sidings are fastened indirectly using the tried-and-tested tongue and groove system – this is a concealed fastening with no visible bolts or rivets, and is a popular alternative to the click-in system. 

It is also important to note that the aluminium siding façade profiles satisfy the requirements of Fire class “A1” as per standard EN 13501-1, meaning that they are non-flammable

Are you looking for a long-lasting wood-effect façade that doesn't require painting? If so, you'll love the easy-care aluminium sidings in the colours “walnut”, “grey oak” and “natural oak”.

Notes

  • The RAL values stated are merely approximate values (~), some of which may differ vastly from the original PREFA colour and, under certain circumstances, may not reflect the subjective perception of the colour. 
  • Above all for colour quality P.10, it is almost impossible to define values due to the surface structure.
  • Plain aluminium: The guarantee does not cover surface appearance alterations caused by processing and environmental influences. Follow the instructions.
  • Metallic colours may vary in shade.
  • To identify exact colours for complementary components please consult original samples.
