Siberian Larch Shadow Gap
Siberian Larch Shadowgap is machined so that each board fits together with adjoining boards to allow dimensional movement. This profile maintains it’s weatherproof integrity and provide an interesting contemporary finish. The boards can be fitted horizontally or vertically.
It’s well positioned where customers don’t have the budget for Western Red Cedar but want similar benefits (stability, durability, aesthetics etc). Siberian Larch is around half the price of WR Cedar based on the current market (where Cedar prices have increased substantially). Our boards will be kiln-dried down to a moisture content of 18-25% to increase stability.
Siberian Larch Grades
We will be stocking only Unsorted Grade Siberian larch,which is the highest available commercial grade. The boards have natural durability. The boards fit in well with our existing cladding range. Other offerings include shadow-gap in Western Red cedar and tanalised redwood, more traditional products in appearance. Increasingly popular is the fibre-cement cladding from James Hardie.
Shadow gap timber dimensions
These larch boards are ex 25mm x 150mm and finish at 18mm thick with a cover of approximately 126mm. A profile drawing is included with images of a recent Siberian larch installation.
Siberian Larch timber fixings
Siberian Larch boards should be fixed with stainless steel screws or nails. We supply a selection of stainless steel annular nails from 25mm to 75mm. Paslode and compatible stainless nails are usually available from stock. Boards should be face fixed rather than secret nailed. Board lengths are subject to availability and they are either 3 or 4 metres.
Siberian Larch timber finishes
Siberian Larch has a mixed combination of light brown hues. Without UV protection the boards will begin to grey naturally within 12-24 months. However, Osmo UV-Protection Oil, including clear and pigmented products, will help to slow down the UV greying process.
