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 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. 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 are classified as non-flammable as per standard EN 13501-1. They satisfy the requirements of fire class “A1” as well as fire class "A2-s1, d0" for walnut, grey oak and natural oak. You 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.

Difference between gap and shadow gap

The large-format sidings 500 and 600 from PREFA are exactly the right cladding material when it comes to large areas such as walls of large buildings in the industrial sector. Thanks to the larger construction widths, hundreds of square metres of façade are covered safely and well protected in the shortest possible time.

Even in commercial and industrial construction, appearances matter. After all, architects and clients also want to clad commercial buildings beautifully as well as robustly: This is why the larger widths of sidings 500 and 600 are also an advantage for the appearance of façades. The eye is oriented towards proportions, thus larger elements are also required for larger areas.

The image shows different construction widths (138, 200, 300, 400, 500, 600) of PREFA sidings in different colours.

With two new sizes (500 and 600 mm), we offer even more variety in terms of width. The new widths of PREFA sidings are available in a variety of popular colours.

Perforated siding – versatile design options

The perforated sidings are a versatile design element in the façade area. They offer different possible applications: whether for enclosures on flat roofs, privacy protection for staircases and multi-storey car parks or for covering window openings.

The façade panels from PREFA, siding, are now also available in perforated versions, sand-brown perforated elements are combined with grey panels here.
