Larch is very resinous and extremely hard-wearing, making it one of the toughest and most durable softwoods in the world. Larch Profile makes excellent decking for both residential and commercial projects, and benefits from impressive dimensional stability, low cost of installation, low maintenance and high manufacturing standards. Larch has a natural resistance to decay. 

WarmDeck decking boards, made from ThermoWood, combine excellent durability and a stylish appearance. Durability is one of the most important characteristics of a decking product. Thermal treatment provides the wood with an excellent biological durability, its decay resistance class is I-II and its usable life is many times greater than that of untreated wood. WarmDeck’s moisture content is half that of normal wood and surface splitting caused by UV-radiation will be less than with normal wood.
