Timber Slatted Blinds explained

Timber Slatted Blinds Timber slatted blinds are one of the earliest forms of sun screening that were developed from the timber shutters that covered window openings before the advent of glass. The modern blind dates back to the 18th century and is the original venetian blind. Whilst most are made with the same components as aluminium blinds, reproductions of the early blinds with timber rail sections and cast fittings are also available. As a natural material, timber is subject to movement and for timber blinds it is only possible to use timbers that are stable in the form of narrow strips. The timber has to be dried to moisture content of between 6-8% to maintain this stability and reduce warping to a minimum. The timbers most generally used are western red cedar and basswood other timbers can be used for special applications. Timbers with a decorative grain can be used, but tend be unstable and warp. Cedar is a very grainy wood, with a distinctive variation in colour that is its attraction. Basswood is a lightwood with a more even grain, which is preferred when a more even colouring is required. Ramin is now rarely used for blinds, as it is an endangered species and subject to CITES controls. Simulated timber slat is also available. Made from polymers often combining a percentage of wood sawdust, it has the appearance of grain and colour of real wood.
