Vertical Grain Siberian Larch

VG SILA (Vertical Grain Siberian Larch) is a naturally durable and aesthetically refined timber cladding product.

Finger jointed boards allow for long lengths of up to 6 metres.

Our current stock of Siberian Larch was procured pre-conflict and as such retains it’s FSC and PEFC accreditation and chain of custody.
