Supporting and bracing wooden component parts must be protected through the utilization of suitable constructional, but also chemical measures against wood damaging influences (DIN 68800 sections 2+3). According to the class of danger a preventive chemical protection can possible be required even on wooden parts that have already been installed. Even here a detailed planning for each individual case is necessary. So- called boric salt compounds can be utilized here (not fixing wood protective mediums) or fixing wood protective mediums for a surface treatment. In especially endangered areas injections can be implemented or boric salt cartridges can be installed. Controlling wood protective measures require a prior specialist report concerning type, extent and vitality of the damage.
Alongside the chemical control from wood destructive insects (old house borer beetle, woodworm or common furniture beetle etc..) if there is a infestation by real dry rot (house fungus) a injection or surface treatment must be implemented with an approved dry rot inhibitor. The last mentioned is implemented preferably as a foam treatment, which guarantees a deeper penetration and a lower protective medium loss. According to the planning for individual cases thermal measures such as heated air treatment or the utilization of technical microwaves can also be implemented. If infested with wood destroying fungi the damage cause (moisture) must be removed through appropriate constructional measures. Implementation must be carried out by a specialist company with the appropriate knowledge required for preventive wood protection.
