Guide for impregnated roof battens

In addition to the usual rough-sawn or planed roof battens, there is always an impregnated version. You can read everything about impregnated roof battens here.

Background information

According to the DIN regulations, roof battens do not necessarily have to be impregnated, as the risk of fungal or pest infestation on the roof structure or on ventilated facades, for which roof battens are usually used, is negligibly small. In individual cases, however, it can be quite different. Occasionally, battens are also used for other structures where they can come into contact with moisture. Impregnation of the roof battens makes sense there, of course.

What to look for when buying? / Recommendations

When buying, you should make sure that the dealer actually complies with the DIN regulations when it comes to wood quality, and not with the "Tegernsee customs" that were previously in use. Many long-established wood processing companies still do that in some cases.

Observe residual moisture and lath spacing On the one hand, the DIN regulations stipulate certain residual moisture values in the structural area - usually below 20% - and lath spacing, support width and grade of the wood must be coordinated - otherwise a corresponding static proof is required. By the way, chemical wood protection is not permitted for roof battens according to DIN and must not be used.
