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. You can find out more about rear-ventilated façades here.

Design options with PREFA sidings

With the PREFA siding façade, you can put together your own personalised façade solution. Choose from four different widths: 138 mm, 200 mm, 300 mm or 400 mm, and a range of surface textures: smooth, stucco or lined. With a range of 24 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. Take some inspiration from reference projects that feature PREFA sidings!

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-flammableYou can find more information about fire protection here.

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”. You can find more inspiration for wood-effect façade cladding here.

1 The colours P.10 stone grey, P.10 sand brown, P.10 rust brown, P.10 patina green, natural oak, grey oak, walnut, patina grey and plain aluminium reflect natural tones and are therefore subject to slight variations in colour, which give the products their unmistakable character.

3 Metallic colours may vary in shade.

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. Furthermore, the colours P.10 stone grey, P.10 sand brown, P.10 rust brown, P.10 patina green, natural oak, grey oak, walnut and patina grey reflect natural colourings that are composed of several colour tones. 
  • To identify exact colours for complementary components please consult original samples.
