Information

The square, aluminium complete system sets new standards for drainage. Thanks to its minimalist and elegant design, it is ideal for use on modern structures. The innovative aluminium products are not only particularly robust, but also visually very eye-catching. Through brackets on the rear side, the square down pipe skilfully blends into the façade without any visible fasteners. The PREFA drainage system is made of up twelve different components such as square downpipes with radii corresponding to the box gutters, various downpipe elbows with a 72° bend, outlet connectors and a leader head with a square outlet.

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.

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, light wood, dark wood, and patina grey reflect natural colourings that are composed of several colour tones.
  • To identify exact colours for complementary components please consult original samples.
