Our Siberian Larch timber is kiln-dried and THERMO MODIFIED wood products will no longer be able to absorb water. In turn, this reduces the wood's ability to expand or contract, which is one of the leading causes of water absorption and rot in outdoor uses. This lack of moisture content in the wood means that the wood's cellulose will no longer act as a "food source" for fungi or insects. In essence, the cooking of the wood with high heat creates a naturally durable wood product that will, in theory, be permanently resistant to water, fungus, insects, and decay. So that's why can we give you a LIFETIME WARRANTY on our timber! https://www.buildwithrise.com/stories/thermally-treated-wood

with 3-4% moisture content, cladding vertical shiplap profile. Sizes: 140x20 mm with 115 effective cover. Length is mostly 6 m but some boards can be 3m long. PRICES:$12 (+gst) per LM depending on the volume of your order. I can give you a bigger discount for a sufficient order, just ask. Siberian Larch has a high-density level (680 kg/m3 dry) with natural decay and termite resistance. Siberian larch doesn't require any treatment even if you use it outdoors. But NZBC required oil treatment for any timber cladding including even Siberian Larch.
