With an industry leading 10 year guarantee, their glazing paint coating system was specially developed to offer maximum performance and protection from each coat.  Allowing the individual characteristics of the timber to show through, the advanced coating system also allows the timber to breathe.  Special consideration is given when selecting the timber that is used, ensuring that they not only look at strength and stability, but its compatibility with their advanced coating system to ensure that their products require minimal maintenance.  First of all a Base flowcoat is applied, containing a specifically designed preservative alongside a basecoat which penetrates the timber.  This provides excellent protection against damaging UV radiation.  Then a Mid flowcoat follows, involving the application of a second flowcoat, but this time a clear solution which penetrates the timber in order to provide protection against moisture. This provides a perfect base for the later spray applied coats. Next a Mid coat is applied with special properties for the timber’s protection and to regulate its moisture, in addition to providing the perfect surface for the adhesion of the top coat.  Lastly, the Top coat is applied in the required colour.  The spray coats are applied using a robot purpose built for this application and each product is then hand finished by their skilled craftsmen.

All George Barnsdale windows are manufactured from sustainably sourced engineered timber as standard. All of their timber is sourced with FSC® Chain of Custody and is specially selected for its outstanding environmental and performance credentials.  All George Barnsdale frames and window sashes are manufactured from Engineered Redwood as standard. By utilising this engineered timber, they achieve very good dimensional stability and durability, as well as very good thermal performance. The increased stability and reduced moisture uptake of the timber produces a substrate which results in an enhanced coating life span (this being the key to a long life window). In addition, it is also engineered to be knot free, which not only benefits the aesthetics, it also prevents resin exudation, which damages the coating.  Due to increased exposure to weathering, the cill on all products is manufactured from FSC® sourced hardwood.
