Treated Pine (Deck)


The larch is a small to medium sized tree 6-30 m and occupies a variety of habitats from dry acidic sandy uplands to swampy lowlands, and can survive in very poor conditions.

The larch is currently used for joinery, flooring, paneling, roofing, carpentry and shipbuilding etc. In the market is available in sawn timber and laminated timber format. The larch wood is a moderate to heavy weight and moderate hardness to hard, dense and late. The heartwood is yellowish-brown to tan with resin smell after logging or processing. The sapwood is whitish or yellowish, with large axial ritinoforous conductors.
It shows moderate resistance to fungal infestations, insects, marine borers organizations. Dried and soaked in sapwood relatively easily, but not so easily in the heartwood.

The impregnation is demanded for long term protection of wood against fungi and insects, either used at internal or exterior, in contact with the ground or not. Contributes to lengthening the life of the wood. The impregnating material is a wood preservative based on water containing copper and proven organic biocides. By immersing the timber penetrates into the structure and is integrated with it so that its removal is impossible.

Treatment is compatible although problems arise from the resin. Holds nails and wood screws fairly well and has good behavior in welding and painting while smoothing is rather moderate due to resin.
