Plywood 101: Differences Between BWP & MR Plywood
Mar 27, 2023 | By: admin

Plywood is the shape-shifter of building materials, with a mystique that’s capable of transforming into its relevant requirement, thanks to thin layers of wood veneers glued together with a powerful adhesive. On the back of its impressive strength, durability, and versatility, plywood is a go-to choice for building a sturdy frame, crafting a beautiful piece of furniture, or designing an eye-catching house interior. It's the dependable workhorse that can adapt to the needs of any project, making it an essential raw material for any builder's arsenal. 

BWP (Boiling Water Proof) and MR (Moisture Resistant) plywood are the two most prevalent varieties of plywood on the market. The fundamental distinction between the two is their capacity to withstand temperature and moisture.

Now, the question arises which type of plywood is better?

But before that, let’s know the fundamental differences between the two variants.


What Is the Difference Between MR and BWP Plywood?


Boiling Waterproof (BWP) plywood is specifically designed to resist water and moisture. It is made with phenolic resins that make it highly resistant to water & can withstand being submerged in water for prolonged periods. BWP plywood is typically used in areas where there is high humidity, such as bathrooms, kitchens, and outdoor applications like exterior cladding, shutters, and furniture.

On the other hand, Moisture resistant (MR) plywood is not designed to withstand water and moisture to the same extent as BWP plywood. It is made with Melamine Urea Formaldehyde (MUF) synthetic resin used as per IS:848-1974, which provides moderate water resistance, but may not sustain prolonged exposure to water. MR plywood is commonly used for interior applications, such as cabinets, furniture, and wall panelling. It is ideal for areas with high moisture & humidity.


Which Is Better, MR or BWP Plywood?


Both BWP and MR plywood have distinct characteristics that make them appropriate for a variety of applications. BWP (Boiling Water Proof) plywood is specially developed to withstand moisture and water, making it perfect for outdoor and maritime applications. It is manufactured with high-quality glue, making it extremely robust and resistant to delamination. 

MR (Moisture Resistant) plywood, on the other hand, is less expensive and better suited for indoor use where humidity is not excessive. MR plywood is not water-resistant and should not be used in wet environments. 

The decision between the two is determined by the application, budget, and amount of moisture resistance required in your area.


Are IS-710-Compliant Plywood Boiling Waterproof?




IS 710 is an Indian Standard specification for boiling waterproof (BWP) grade plywood. IS 710-compliant plywood is waterproof and can withstand boiling water for several hours without delaminating or losing structural integrity.

However, it should be noted that IS 710-compliant plywood is not completely waterproof. While it can withstand water to some extent, it is still susceptible to damage if exposed to moisture for an extended period. As a result, it is critical to protect IS 710 plywood from moisture and water by sealing its edges and surfaces with a suitable coating or paint.


Is BWP Ply Good for the Kitchen?




BWP plywood is an excellent choice for use in the kitchen because it is moisture-resistant and can withstand exposure to water, steam, and humidity. This makes it ideal for use in areas prone to moisture, such as kitchens and bathrooms.

However, it is important to note that not all BWP plywood is the same. The quality of BWP plywood varies depending on the brand, manufacturer, and grade. As a result, it is critical to purchase BWP plywood from a trusted source and check its quality before using it in your kitchen.
