During the decoration process, you often hear the word "backboard plywood", so what kind of board does backboard plywood refer to? Where is backing plywood usually needed? Today we will talk about "back plywood".
Backboard plywood thickness

When the air is humid every year, if the moisture-proof performance of the wardrobe is poor, it will cause the clothes and bedding to be damp and moldy. Backboard plywood generally refers to the board of the cabinet against the wall. Generally, it is not load-bearing. It mainly plays the role of dust-proof, moisture-proof and stable. The thickness varies from 5mm to 18mm. Wait. In order of stability, multi-layer solid wood board > particle board > particle board.
Backboard plywood of different thicknesses:
5mm backboard plywood: It can be used for cabinets between 1m and 2m.
The backboard plywood is less likely to deform due to its small force. If the cabinet exceeds 2 meters, it is not recommended to use, because the thickness of the board should not be subjected to excessive force, otherwise it will cause cracking and deformation.

Backboard plywood of different thicknesses

9mm backboard plywood: 9mm is one of the most conventional backboard plywood thicknesses at present. If there are no special circumstances, you can choose 9mm, which is stable enough and economical. In addition, the thickness of 9mm will not cause the cabinet to protrude, and the depth will be shortened, resulting in less space for use inside the wardrobe. In general, this thickness of plate is cost-effective and suitable for general decoration needs.
12-18mm backboard plywood: The backboard plywood that exceeds 10mm is relatively thick. Usually, the backboard plywood is required to be thicker because of the special structure of the cabinet. As for the thickness, you can decide according to the actual situation. There is a misunderstanding here.
The thicker the sheet, the better the moisture-proof performance. In fact, the moisture-proof performance is not increased due to the increase of its thickness, but is related to the sheet structure and edge sealing.

Custom Cabinet Back Panel Plywood

Let's compare the thickness of the plywood for the back panel of the custom cabinet.
①5mm backboard plywood is suitable for small cabinets;
②It is recommended to use 9mm back plywood for custom wardrobes, which is cost-effective and can basically meet the stability and moisture resistance of the wardrobe;
③It is more secure to use plywood with a back panel of more than 12mm for the cabinet where heavy objects are placed, but the cost is slightly higher.
Generally, the back plywood of the cabinet can be made of thin plates. If there is a special structure, the back plywood can be thick. Like cabinets, there are many people who don't use backboard plywood, because the kitchen is relatively humid, and there are sinks, gas pipes, small kitchen treasures, etc., no backboard plywood can be convenient for later maintenance, and cleaning is more convenient. Of course, whether the cabinets use backboard plywood varies from person to person, and there is no prescribed requirement.
