Wooden outdoor structures must withstand the forces of nature. Untreated wood will not last in conditions in which it is exposed to moisture, heat, and oxygen because it reacts to changes in the moisture content of the surrounding air. This will lead to cracking and decay. Thermowood is capable of maintaining its size and shape and resisting mould and decay in conditions in which the properties of untreated wood are insufficient. Thermowood should always be coated in accordance with its intended use.
Lunawood maintains its size and shape extremely well. Lunawood Thermo-D pine reacts 40% less to changes in the moisture content of the surrounding air width-wise than corresponding chemically treated wood. This facilitates the use of the Lunawood Profix fastening system in the most demanding Nordic conditions.
In natural conditions, Lunawood’s moisture content is roughly half that of untreated wood. Ultraviolet radiation causes less cracking in Lunawood than in untreated wood.
UV radiation causes the original colour of the wood to fade. To maintain the original colour, it is recommended that the wood is treated with a method that protects it from UV radiation.
Lunawood Thermo-D pine’s thermal insulation capability is roughly one fourth higher than that of untreated pine. This is reflected in lower energy consumption: there is less need for heating in a cold climate, and less need for air conditioning in hot conditions.
