British Larch Cladding

British larch is a tough and naturally durable softwood grown in local woodlands that is ideal for external cladding in exposed areas. British larch is ideal for tight budgets.

British Larch Cladding Features

British larch cladding is both tough and durable, making it ideal for exposed elevations and areas where knocks and scrapes are likely. Larch is also our most cost effective cladding option.
British larch is a completely different specie to Siberian larch and they look very different. It is important that you are clear about which version you are asking for.
Although we sell most of our larch in wet sawn profiles such as feather-edge, British grown larch can also be dried and machined to various cladding profiles. Our dried larch cladding is either available in a relatively clean Grade A or a cheaper but more knotty grade B. The grading is very similar to that of Siberian larch.
For a comparison between British and Siberian larch watch our video.

British larch ranges in colour from pinky-brown in the heartwood, to creamy-white in the sap band. Depending on the grade, there will be some or many dark brown knots and occasional resin pockets along the length of the board.

British larch weathers relatively slowly, often taking two years to reach a silver-grey patina. Larch is quite consistent and is not reactive, and as such, will weather relatively evenly. Northerly elevations may weather to a darker grey than those facing South.

Desired service life
Occasionally wet 30 yrs. Frequently wet 15 yrs.

Movement class

Resistance to impact

Working properties
Good workability. Takes fixings satisfactorily although can be prone to splitting.

570 – 650 Kg / m3

British larch contains resin rather than oil or tannin.


How to fix
Pre-drill and hand nail with stainless steel nails through the face. Do not attempt to secret nail through the tongue. We do not recommend first or second fix nail guns with larch, because it can be an unstable timber.

** Be sure to leave an expansion gap between machined boards**
