When it comes to choosing plywood for kitchen cabinets, it is recommended to use plywood that has good moisture resistance. In that regard, two common types of plywood used for kitchen cabinets are BWR (Boiling Water Resistant) and BWP (Boiling Water Proof) plywood.
BWR plywood (Boiling Water Resistant) is suitable for areas with high humidity, such as kitchens. It is made with phenolic resins that make it resistant to moisture and boiling water for a certain period. BWR plywood can withstand occasional exposure to moisture, but it is not completely waterproof. It is a more affordable option compared to BWP plywood.
BWP plywood (Boiling Water Proof), also known as Marine plywood, is considered the highest grade of plywood in terms of moisture resistance. It is specifically designed to withstand prolonged exposure to water and moisture. BWP plywood is made using phenolic resins that provide excellent waterproofing properties. It is more expensive than BWR plywood but offers superior durability and resistance to moisture-related issues.
For kitchen cabinets, both BWR and BWP plywood can be suitable choices. If your kitchen experiences occasional exposure to moisture, such as spills and splashes, BWR plywood should suffice. However, if you anticipate higher levels of moisture or want to prioritize maximum protection against water damage, BWP plywood would be a more appropriate option.
It's important to note that regardless of the type of plywood you choose, proper installation, sealing, and finishing are crucial for ensuring the longevity and durability of your kitchen cabinets.
