Provide a 6 pages analysis while answering the following question: Dendrolight, Engineered Wood Construction Material. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. Alternate layers of these sawed combs are glued turned 900 to each other as shown in the picture on the right which gives the structure its rigidity. Solid wood external trims are added, again by gluing, to form a completed panel. Depending on the strength and rigidity needed, the sawed wood structures can be made in different formations as shown below. Note that in the lower picture, the end-pieces are sawed at a 450 angle. The upper picture has another variant of shape for the end-piece (Lathams, 2012).
The creation of voids in the panel is at the core of the Dendrolight technology. This reduces the weight of the panel without sacrificing strength or rigidity. This is the core idea for which the inventor of the product, Johann Berger of Austria has been granted a patent. This process in Dendrolight reduces the wood content of the panel to 40% and the material reaches a weight as low as 250 kg per cubic meter. For comparison, Aspen wood has a weight of 420 kg per cubic meter, Spruce wood has a weight of 450 kg per cubic meter and Pine depending on the species, has a weight between 350 and 660 kg per cubic meter (Simetric, 2011). This weight is also significantly lower than other engineered wood panels including plywood, particle board, MDF and Oriented Strand Board which are in the range 400 – 700 kg per cubic meter (Berger, 2006).
The sawed middle layers are built up by gluing to blocks of the maximum size of 3 meters length, 1.35 meters width and 600 mm thickness. From this block, pieces are cut by band saw to the desired dimensions. The thickness can range from 14 mm to 200 mm. The band saw cut customized pieces are finished by adding face layers on both sides, made of plywood or any other desired material of 3 mm to 6 mm thick. The faceplates are also glued to the lamella middle layer.
