Product Description

British Larch Beams

iWood's British Larch Beams are cut fresh to your sizes in UK sawmills. It has light brown colouring with towards orangey hues.

With regard to its price, strength and durability properties, its very similar to British Douglas Fir.

The main benefit of Larch, is that it's the only British timber that can easily be graded to the BS 4978 C24 Strength Class.

British Larch Common Uses

British Larch is used widely in construction for timber framing, trusses and A-frames, as well as outdoor structures and for fence posts. It's heavily used in house building and where certain strengths need to be attained.

It's suitable for most applications where you might use Oak, but with a lower price.

British Larch Appearance

Home Grown Larch is fairly straight-grained with strong and clear annual growth rings. The timber has a warm, pale orangey colour, sometimes going into a pale pinkish red.

It is a fairly knotty timber which adds to its character.

Grades of British Larch

The price above is for our high quality Fresh Sawn Merchantable grade home-grown Larch. This is suitable for the majority of Larch work unless a specific strength class is required.

Customers sometimes come to us needing British Larch specified to a specific Strength Class. Larch is the only British Beam Timber that can be easily graded to C24, an incredible high strength grade, with similar timbers only achieving C18, unless provided in large section sizes.

It's more commonly requested to C16. These strength classes are sometimes requested by architects or structural engineers in order to perform structural calculations on the structures being created with the timber.

If you need Larch graded to C18 or C24, please send us the list of the sizes you need and we will quote them for you.

Sizes of British Larch Beams

We offer Larch beams in thicknesses and widths from 25 to 300mm, and in lengths up to 6m. We can sometimes source sections outside of this range so check availability with us if required.

It is standard practice to supply the beams over-length for you to cross-cut exactly on site.

These beams are rough sawn and so will have a tolerance of +- 4mm or so. There will also be slight band saw marks on the surface, which is to be expected often cherished for the look it gives. You can feel free to plane or sand them smoother when you receive them.

Grown In Britain

iWood is a proud, certified member of Grown in Britain, the UK's initiative to prove the source of timber at every step of the supply chain. Ask if you need your timber to be Grown in Britain certified.

Benefits of British Larch Beams

As with all British timbers, the reduced transport requirements make Larch incredibly environmentally friendly when compared to imported timbers. It has a very low carbon footprint, which is becoming more and more important for a lot of new builds.

While it can make it slightly trickier to work with, British Larch can contain quite a lot of resin, which gives it great rot-resistant properties and means it doesn't require any form of treatment. This is only anecdotal, but many people swear by British Larch for fence posts, even over European Oak, which is technically a more durable timber.

What Other Timbers Might I Consider?

Price-wise, British Larch Beams are on par with British Douglas Fir Beams. If you are the decision maker, the slight difference in colour may sway you so have a look through the photos.

As for the other British Timbers, the slightly more expensive British Western Red Cedar Beams are more durable, yet still have a low carbon footprint.

If you're looking for the best durability, you could consider European Oak beams. They're slightly more expensive but are a lot more durable (10 + years over Larch) and are also available planed.
