Wooden Timber Windows, Doors and Stairs
High Quality, Long Life, Bespoke
Specifying Tips
Simple changes in design and specification can have a major influence on the durability and maintenance of external joinery.
Where possible design external joinery in reveal
Traditionally windows & doors were always set in reveal (& in Scotland still are)
This was one of the reasons they had such long life. Extended timber cills have the most exposure and will be the first section to fail.
Always specify End-Grain Sealing
When mortice & tenon joints were used, they were sealed with lead based primer prior to assembly. As these joints are no longer viable it is important to ensure that the unexposed end grains are properly sealed. If they are not the end grain will draw up large volumes of water if even a small crack appears across the joint.
Always specify factory finishing
Factory finished joinery that is dip coated in primer and coated with high build paint will out-last site finished joinery by years.
Rain and fog do not affect finishing systems in a factory
environment.
As an example Barnsdale pre-finished windows are guaranteed for 7 years. They will then only need a thorough wash down and a simple one coat application of paint.
