SILVALarch™ Boards

There are a number of end uses for SILVALarch™ boards, from board-on-board (board and batten) style cladding to open jointed cladding, fascia, barge boards, door and window trim, horizontal slatted screens, fences and more.

For board-on-board style cladding, simply space an inner layer of boards apart with an outer layer of boards or battens covering the joints for an attractive double layered effect. Use different widths of board and spacings to create a range of bold shadow line effects that will add a sense of depth and texture to a facade.


Slow Grown Timber Imported from Irkutsk Region of Russia

Siberian Larch is more dimensionally stable, denser and more durable than its cousin European Larch, mainly due to its slow growth caused by the long cold winters and short summers of Russia’s Irkutsk region. The timber has a tight grain with relatively few sound tight knots, and is of an exceptional quality that far exceeds the official 'GOST 26002-83' grading standards.


Kiln Dried

Our SILVALarch™ boards are kiln dried to a moisture content of 16-18% (+/-2%). Controlled drying is preferable to air drying as it enables the wood to achieve a consistent moisture content, making it more dimensionally stable and ready for immediate coating.

A Full Range of Components and Accessories

We also stock Tyvek® breather membrane, stainless steel nails, corner sections and a wide range of coatings and cleaning products – everything you need to complete the job.
