Sierra is a line of engineered flooring with a subtle sawn face of European oak. The sawn surface creates an almost textile texture on the top and edges of a board. The sawn surface of each board is non-repetitive. As stains are absorbed, striations of colors are created, resulting in a striking contrast in tone. Specialty colour treatments are applied in nine standard offerings. Each colour demands a sequence of treatments which include one or more of the following: smoking or fuming, oiling, and staining. All Sierra floors have an oil finish to maintain the texture and appearance of the real wood while providing a protective seal.
The top layer of the engineered boards consists of European oak (FSC available on request). The backing is made of FSC birch plywood. No added urea formaldehyde plywood is used. For adhering the backing a LOW VOC adhesive is used; the finish is VOC free. Sierra is for indoor usage, primary as flooring, but other usages could be wall treatment, furniture wrap or stand-alone furniture. Available sizes are 20mm thick x 180mm wide planks, 20mm thick x 240mm wide planks, and 15mm thick x 180mm wide planks. Planks are available in lengths from 1790mm up to 2470mm.
