Knowledge of backboard thickness, which directly affects the quality of custom cabinets

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

The southern region experiences the plum rain season every year, bringing high humidity. If a wardrobe's moisture-proofing isn't good enough, clothing and bedding can become damp and moldy. The backboard generally refers to the wall-mounted panel of a cabinet. It's generally non-load-bearing and primarily provides dust and moisture protection, as well as stability. Thickness ranges from 5mm to 18mm, and materials include particleboard, particle board, and multi-layer solid wood. In order of stability, multi-layer solid wood > particle board > particle board.

Back panels of different thicknesses

5mm backboard: can be used for cabinets between 1m and 2m. The backboard is less likely to deform due to less stress. It is not recommended for cabinets exceeding 2m, as this thickness cannot withstand excessive stress, otherwise it will cause cracking and deformation.

9mm back panel: 9mm is one of the most common back panel thicknesses currently available. If there are no special circumstances, 9mm can be selected. It is stable enough and economical. In addition, the 9mm thickness will not cause the cabinet to protrude, the depth to become shorter, and the internal usable space of the wardrobe to become smaller. In general, this thickness of board is cost-effective and suitable for general decoration needs. 12-18mm back panel: Back panels exceeding 10mm are relatively thick. Usually, the special structure of the cabinet requires the selection of thick back panels. As for the thickness to be selected, you can decide based on actual conditions. There is a misunderstanding here. The thicker the board, the better the moisture-proof performance. In fact, the moisture-proof performance does not increase with the increase in its thickness, but is related to the board structure, edge sealing, etc.

Let's compare how thick the back panel of the custom cabinet should be.

①5mm back panel is suitable for small cabinets;

② It is recommended to use 9mm backboard for custom wardrobes, which is cost-effective and can basically meet the stability and moisture-proof requirements of the wardrobe;

③ Cabinets for placing heavy objects are more secure with back panels thicker than 12mm, but the cost is slightly higher.

Generally, thin back panels are sufficient for cabinets. However, for special structures, thicker panels can be used. Many people don't use back panels for their cabinets, as kitchens are humid and contain sinks, gas lines, and small appliances. This makes it easier to maintain and clean cabinets without back panels. Whether or not to use back panels for cabinets is a matter of personal preference and there are no set requirements.
