In which cases is impregnation necessary?
Wood is a perfect material that human needs for his construction. It is a material with many advantages, but also with disadvantages too. It is a fact that wood that is subject to initial industrial maintenance can be placed for long periods in permanent or non-permanent constructions. Impregnation is one of the ways in which human can cope, but also confine restrict some of the disadvantages of wood. Therefore the wood is impregnated with various chemical substances-preservatives.
Does the impregnation give extra life to wood?
Thanks to impregnation, preservatives are penetraτe into the wood, which are considered necessary to protect it. It is thus understood that in that way the lifetime of wood is multiplied as it is protected from adverse weather conditions. So, the lifetime in impregnated woods is longer than the expected to no-impregnated wood.
What is the purpose of impregnation?
With the impregnation of wood, especially that used in external spaces with or without contact on the ground, we manage to protect it from:
I. fungus (humidity)
II. incects (termites)
Let's resemple the wood with a sponge. A sponge that absorbs every good ingredient to its advantage. The aim of the impregnation is to coat each cavity and each cell of the wood with the appropriate amount of preservative in order to achieve more effective wood protection at the maximum possible time horizon.
How safe is the impregnated timber?
The impregnated wood is absolutely safe for human, as well as for the environment, flora and fauna. This is of course true if the impregnation is done with specific preservatives, which will be of high quality, certified researches that have been done in past and continues on a daily basis. European regulations as well as international researches have approved some specific methods and impregnation chemical substances.
Of course, the wood submersing method is also marketed, which must be emphasized that it has nothing to do with classical impregnation in a vacuum pressure plan. The main difference is that the submerged wood has a surface coating in contrast to impregnated wood which is supplied with pressure preservatives. This pressure results in the wood for being supplied with the maximum protection.
The consumer should check the quality of impregnation (perhaps with a sharp object), as the difference in both the quality and the price between impregnated and submersed wood is quite large.
