Forsgrens Log Houses

Forsgrens Timmerhus is Sweden’s largest log house manufacturer. 30 years ago, we invented and patented the so-called heat-retaining timber technology. Since then, all our houses have been manufactured using this technology. It is important for us to build as environmentally friendly as possible, including insulating the houses so that both the environment and the wallet benefit.

This is what we think about the tar paints:

Several of our customers have painted with Tjärvitriol, Svarttjära, and Rödtjära. All are very satisfied with the result. We have also seen that Tjärvitriol works excellently on houses that have previously been painted with Järnvitriol. Auson’s product range also fits into our “thinking” of building as environmentally friendly as possible.
