BULLINGER's KVH is

a visually sorted, kiln dried and surfaced solid structural timber. It is used for both visual and non-visual applications in modern wood construction and frameworking. This solid, finger jointed construction lumber (KVH) is made from Spruce, White Fir, Larch and Douglas Fir. KVH is used for projects that demand higher than normal standards and require specific design values. KVH is produced from precisely sized, stable raw material. BULLINGER's finger-jointing line allows production of different lengths in order to satisfy different customer requirements (see service performance). With today's modern construction methods, there is a greater emphasis on high quality wood usage. This is similar to former times when unseasoned (green) lumber was produced to high quality standards. KVH is a standardized commodity in today's market (see physical properties).

Due to the ideal moisture content of the wood, it is not necessary to pressure treat (chemically impregnate) the product. Provided that the product is handled and used for the appropriate application, then a healthy living environment and longer lifetime of the house is guaranteed. Douglas Fir and Larch should be used for any outdoor application where durability is required.
