Träullit is a traditional family business, founded in 1946 by Lennart Rääf. Today it is led by Bengt Rääf. Since then, the company has manufactured wood wool panels and slabs, and now also exterior walls. Wood wool spruce is a fantastic material sprung from our nature, joined with pure cement. Our head office and factory is located in Österbymo in southern Östergötland.


Our mission is to develop, manufacture and sell the best products of cement-bound wood wool. Its properties provide excellent heat insulation, high heat storage capacity, good sound absorption, documented high resistance to fire, mould and rot. It is also a mechanically strong material.
