Comparison of MR Grade & BWP Plywood

Plywood is a versatile building material, valued for its strength and adaptability. Among its many types, the water-resistant category is often the focus. In this article, we compare two popular plywood grades: Moisture-Resistant (MR) Plywood and Boiling Water Proof (BWP) Plywood. In this blog, we will highlight their features, differences, and ideal applications to help you make an informed choice.

Key Differences Between MR and BWP Plywood

1. Resistance to Termites

MR plywood is designed with adhesives and additives that make it highly resistant to termites. MR grade plywood from SharonPly also comes with a warranty, ensuring long-term reliability.

BWP plywood, on the other hand, provides enhanced termite resistance along with additional durability features, backed by a longer warranty period.

2. Certification by BIS

MR and BWR plywood are certified under the IS 303 standard.
BWP plywood belongs to the special category of IS 710, ensuring superior waterproofing and strength.

3. Water Resistance

MR Plywood: While moisture-resistant, MR plywood is not waterproof. It performs well in humid conditions, making it suitable for interior applications.
BWP Plywood: BWP plywood is completely waterproof and highly resilient to fluctuating weather conditions, ensuring no delamination even in prolonged exposure to water.

4. Pricing

MR plywood is cost-effective and performs well in controlled indoor environments.
BWP plywood is more expensive but offers unmatched durability and water resistance, making it worth the investment for demanding projects.

5. Strength and Durability

MR plywood is strong, durable, and long-lasting for interior use but cannot match the robustness of BWP plywood.
BWP plywood is the strongest option available, with its strength determined by the number of plies, density, and the quality of resins and adhesives used in its construction.

Applications of MR and BWP Plywood

MR Plywood Applications

Ideal for indoor furniture and spaces with limited exposure to water.
Commonly used in beds, sofas, tables, chairs, wardrobes, and TV units.

BWP Plywood Applications

Perfect for outdoor furniture and areas exposed to water, such as kitchen cabinets, bathroom furniture, and outdoor structures.
Suitable for regions with fluctuating weather conditions.

Both MR and BWP plywood grades are strong, durable, and reliable. However, BWP plywood’s waterproofing and superior strength make it the ideal choice for demanding applications. Assess the specific requirements of your project to select the plywood that best suits your needs. SharonPly’s BWP plywood offers unmatched durability, termite resistance, and waterproofing capabilities. It meets the stringent IS 710 standard, ensuring long-lasting performance even in the harshest conditions.
