Wood is a perishable material, hygroscopic and fuel, which cause attention to selecting the wood species that is going to be exhibited in relation to humidity and soil. With variable depending on its humidity and moisture from the atmosphere or soil, wood is a good living environment for fungi and insects, but suffer biodegradation processes and dimensional changes. Observations over time on wood building behavior determined limiting actions of biodegradation phenomena, with different products with antiseptic, waterproof and fireproof properties. The development of forestry research and of chemical industry in particular, have put on the market for wood protection treatment a number of solutions which subsequently proved toxic to humans and the environment. Now the latest generation methods and products available to conservators and restorers disposal for use in preserving the old wooden racks and the new one used in restoration. The National Institute Wood throughout over 75 years of existence, helped by laboratory and in situ tests, carried out by specialists, contributed to marketing the new products and ways to protect freshly shot down wood used in construction and in the conservation and restoration of cultural goods. Attempts are made by exposure to fungi, insects and moisture under laboratory conditions or by exposure to natural climate conditions in the polygon NIW. The preventive protection can extend about 3-5 times the duration of use and reduce downgrading quality with over 30% of the wood used.
