(1) Multi-layer timber sections with opposing grains, balances warping and combats twisting
The use of multi-layer timber is long established in Britain for long span timber structures in demanding environments such as swimming pools and bridges. In common use on the continent, but very rare in Britain, is the use for window and door sections. This multi-layer structure is particularly effective in resisting warping and twisting as the opposing grains even out natural moisture movement. And It is the twisting of timber during wet weather, more than the swelling itself, which causes windows and doors to stick. Multi-layer timber sections are used as standard throughout our range.
