We recommend that Danish Oil is used on Oak and Iroko. A thin coat should be applied either prior to leaving the factory or by your builder on site immediately after delivery. A further coat should be applied after fitting.

Silver look to windows can be obtained by allowing the Danish oil to fade. This process takes about a year depending on the amount of sun on the wood. Both Oak and Iroko contain enough natural tannins to keep the wood protected. However the inside of the window must be coated as the wood will stain if rain reaches the open sashes.

Iroko can be stained light oak using the Sadolins 3 coat system. You will then achieve the look of Oak at lower prices. The windows however will not turn silver with age.
