CHARACHTERISTICS AND TECHNIQUES
SMOKING & FIRING
SINGLE SMOKED
DOUBLE SMOKED
FIRED
Smoking and fuming are essentially the same and refer to a process whereby the lamella timber is exposed to ammonia gas for 24 (single) or 48 (double) hours. The colouration is surface deep only and, unlike staining, a smoked tone will vary from plank to plank. Fired products are treated in a vacuum, sometimes for several weeks, and the dark colour runs throughout the lamella providing a genuine visual alternative to tropical hardwoods.
SAPWOOD & TREATMENT
SMOKED & WHITE OILED
SMOKED
NATURAL OILED
Sapwood is the living part of the tree through which water and sap flow. It is always lighter in colour than the heartwood, and certain fuming, smoking and colouring processes emphasise it since it doesn’t react to these treatments to the same degree. By definition sapwood contains more moisture, however this is no cause for concern since all Havwoods’ timber has been carefully dried and its stability is ensured when supplied in an engineered form.
