We specialise in supplying British Western Red Cedar, larch and Douglas Fir either rough sawn or planed.

Rough sawn timber produced straight from our saw mill it has a slightly rough surface and is best used where a planed finish is not required. The type of saw we use gives a smother finish than traditional circular saws.

Prepared or Planed timber must be kiln dried before planning and give a smooth to the touch finish. It best for internal jobs where a quality finish is required but can be used externally. Due to the additional work planed timber has an extra cost, please contact us for prices.

We offer three variants of moisture content within our rough sawn timber products-:

If you require floor boards please see our flooring page, our flooring timber is our best quality product - we hand pick the best timber, kiln dry it and then plane it to produce a superior finish/product.

Treat or leave to age naturally it's a personal choice, Western Red Cedar and Larch due to there durability rating can be used externally untreated. Douglas Fir will need a preservative for external use but is the most cost effective species.

British Western Red Cedar - Home Grown (UK)

Is among the most popular softwoods used today it's natural resistance to decay and moisture absorption means it can typically be installed without treatment. Rated BS EN 350 class 3 moderately durability (see below) and is subject to little movement when installed.

Larch - Home Grown (UK)

More resistant to impact damage and is more suited than Cedar for structural applications. Due to Home grown Western Red Cedar being in short supply (demand far out weighs the supply), Larch is a viable and popular alternative, as well as the first choice for many. Applications include:- support columns, door frames, window frames, floor boards. Rated BS EN 350 class 3 moderately durability (see below)

Douglas Fir - Home Grown (UK)

Is another good softwood being rated BS EN 350 4 slightly durable (see below) it therefore requires a protective coating when installed externally.

When selecting your timber type for your project it is worth taking in to consideration BS EN 350 timber durability class.

Durability is the ability of a species to resist decay either naturally or through preservatives. The Class is based on the ability of the heartwood (inner part of the tree) to resist fungal decay. The sapwood (the living outermost portion of the tree)is considered not durable and should not be used for external projects without preservative.

BS EN 350 has 5 classes of durability they are:-

Class 1 to 3 can be left as untreated timber, a natural ageing process will accrue e.g. Cedar will turn a grey colour. Class 4 and 5 will need to be treated with preservatives.
