Scandinavian spruce (KVH and BSH structural timber, planed timber), thermally modified Scandinavian pine (decking boards, cladding), Siberian larch and Canadian larch (premium decking boards), thermally modified abachi (exterior square profiles), WPC composite (joists and decking boards).
No — our eco-responsible positioning favours retified thermally modified timber (biocide-free) as an alternative to pressure-treated pine. This choice suits the Belgian and Luxembourg markets, where biocide regulations are stricter.
Yes — France, Belgium and Luxembourg. Our thermally modified timber and glulam offer is particularly well suited to these two markets.
