People who have a certain understanding of building materials should know the multilayer board . Multilayer board is also called plywood. It is made of high-quality and regular wood as a panel and coated with resin glue and then produced in a hot press under high temperature and pressure. Now more and more extensive use of multi-layered board, a variety of cabinet design and installation are based on multi-layered board as a substrate. Well, today, we work together to understand the advantages and disadvantages of plywood under which, by the way under the plywood should understand how to choose it. First, what are the advantages and disadvantages of multilayer boards? 1, the advantages of multi-layered board (1) The most obvious advantage of multi-layered panels is that their compressive strength is particularly strong, they are not easily deformed and cracked, and their shrinkage and expansion are less likely. (2) The indoor temperature and humidity can be properly adjusted, and the surface layer of the multilayer board can display the natural wood grain of the wood, and the paving is simple and convenient. (3) Compared with solid wood, multi-layered boards can compensate for defects such as knots, small dimensions, deformation, and large differences in vertical and horizontal mechanics that naturally occur in natural wood. (4) Solid wood plywood also has advantages in terms of price. Multi-layer solid wood panels are more economical than expensive wood panels. 2, the shortcomings of multi-layer board It is also because in the production process it is made of high temperature and high pressure in a hot press after being coated with resin. Therefore, in terms of environmental protection, it may not be so perfect. It is a certain amount of formaldehyde released, and there is bound to be pollution due to glue. This is also the most obvious drawback of multi-layer boards. Second, multilayer board selection skills 1, understand the positive and negative characteristics of the multilayer board There are positive and negative aspects to a multilayer board , so when choosing, choose a clear grain, a smooth and clean front, no roughness, and a flat surface. 2, pay attention to avoid all kinds of defects The multilayer board can not be damaged, tangled, bumps, etc., so we must carefully observe the surface of the multilayer board. 3, see the glue of the multilayer board When you buy a multilayer board, you should carefully observe whether it has a degumming phenomenon. 4, see whether the stitching is perfect Sometimes a multi-layer board is made by stitching together two boards of different textures. At this time, you need to carefully observe whether there is tight joints or unevenness or not. 5, choose not to loose plastic multilayer board When purchasing, you can try to knock the various parts of the wrong laminate by hand. If the sound is crisp, it proves that the quality is better. On the contrary, if the sound is dull, it means that the laminate may have appeared loose glue. The phenomenon. Edit Summary: The above is how small series about the advantages and disadvantages of plywood and plywood picked introduce you, I read the article later, is not for all aspects of multilayer, have a more comprehensive understanding It. Can wood with such advantages and disadvantages fit your purpose? Structural Insulated Panels (SIPs) are high-performance building materials used in wall, roof and floor for residential

and light commercial constructions. The panels are made by sandwiching a core of rigid foam insulation (EPS, PU,
XPS) between two skins of structural/engineered boards such as OSB, plywood, cement board or magnesium board
etc. The dimension of Quacent SIPs varies from 1220mm x 2440mm to 2400mm x 7320mm, and its thickness is from
114mm up to 31 Omm, which can meet the structural and insulation demands of all regions.
Quacent SIPs are all manufactured strictly under IS0900J-2015 quality control system. All the lumber, OSB, adhesive
