Wood durability in the light of recent trends and research on the durability of building materials and components
2000 - IRG/WP 00-20195
Building-related research of today demonstrates a clear shift in focus from the design and production phases to usage and to the entire life time. A consequence is that the performance criteria of materials, components and of the entire building must be regarded over the life time rather than at the time of production or delivery. As one example can be mentioned the Building Construction Directive...

Future insecticidal treatments for wood products
1980 - IRG/WP 3140
Protective measures involving chemical treatment of wood use only a narrow range of toxic materials which are divisible into two groups, (i) those that are water-soluble, (ii) those that are soluble only in organic solvents. It is generally true to say that, as far as protection against insects is concerned, the former are stomach poisons while the latter are largely (though not exclusively) conta...

Serpula lacrymans the dry rot fungus. Revue on previous papers
1989 - IRG/WP 1393
It is found that the Dry rot fungus Serpula lacrymans grows in houses only because of its need for basic materials to neutralize the oxalic acid production or heavy metals which celate the oxalic acid. The average distance from the mycelium to the basic materials is found in average to be 14.2 cm with a variation from 0-100 cm. In contrast to Serpula lacrymans the Coniophora puteana and the Rigido...
