Information

Aluminium does not rust. In addition, PREFA uses a special salt-water-resistant aluminium alloy on its gutters. If the surface becomes damaged, the plain aluminium reacts with oxygen to form a permanently protective oxide layer which protects the gutter from any further damage.

Aluminium is also a fully recyclable material. It can be 100% recycled in an energy-efficient way, without loss of quality.

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.

Note

  • The RAL numbers indicated are approximations only [~] and may, in some cases, differ greatly from the PREFA original colour. They may not be a true reflection of the subjective perception of colour. 
  • Particularly in the case of the P.10 paint quality, it is difficult to precisely define the number due to the nature of the surface structure. In addition, 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 are based on natural colours made up of several different shades. 
  • We recommend obtaining original samples so that you can gain an idea of the exact colours of complementary components.
