Timber Windows are preserved, painted and finished in 5 stages:
Stage 1) The first Chemical preservation stage is completed by direct dipping of the timber window into the preservative solution to protect against moisture absorption.
Stage 2) The second Chemical preservation stage is completed by direct dipping of the timber window into the preservative solution to protect against fungi, pests and mould.
Stage 3) Primer and Undercoats are applied.
Stage 4) First top Coat is machine sprayed to frame.
Stage 5) Top Coat is machine sprayed onto the frame.
The process of “Dipping”
The Dipping process consists of simply immersing the wood in a bath of creosote or other preservative for a few seconds or minutes. Similar penetrations to that of brushing and spraying processes are achieved. It has the advantage of minimizing hand labour. It requires more equipment and larger quantities of preservative and is not adequate for treating small lots of timber. Usually the dipping process is useful in the treatment of window sashes and doors. Treatment with copper salt preservatives is no longer allowed with this method.
Our Colour Palette
Here at Timber Windows Direct we use the Classic RAL colour chart.
RAL is the most popular Central European Colour Standard used today, The colours are standard for use in architecture, construction, industry and road safety.
RAL is a colour matching system used in Europe that is created and administrated by the German RAL gGmbH (RAL non-profit LLC), which is a subsidiary of the German RAL Institute. In colloquial speech RAL refers to the RAL Classic system, mainly used for varnish and powder coating but nowadays there are reference panels for plastics as well. Approved RAL products are provided with a hologram as of early 2013 to make unauthorised versions difficult to produce. Imitations may show different hue and colour when observed under various light sources.
