Our Louvred Windows can be supplied in any standard RAL colour; for details of the RAL numbers please refer to the Fieger Colour Chart, which can be found in the download area of the website. The framework is available as polyester powder painted or anodised. Where insulated aluminium louvres are involved, these can be finished to the same specification as the frames. The standard Fieger colour range includes the most common RAL numbers, which we keep in stock and therefore can offer at a favourable price. Other colours are available, but are subject to special price enquiries.
