Water resistance is one of the significant factors when selecting a plywood for furniture or construction. Plywood comes in various grades that's suitable for different kinds of projects. Among the popular ones are the BWR (Boiling Water Resistant) and BWP (Boiling Water Proof) plywood. Both BWR and BWP are widely used in damp climates. However, one must know the differences between BWR and BWP plywood when selecting a plywood for their project.
What is BWR Plywood?
The BWR plywood, or Boiling Water Resistant plywood, is designed to resist water up to some extent. It is manufactured using a synthetic phenol formaldehyde resin, which makes the plywood resistant to water for some time. Despite its good performance in moist conditions and resistance to splashes of water, the durability of BWR is lesser when we compare BWR vs BWP plywood. BWR plywood is used in areas that are exposed to humidity but do not have direct or constant contact with water. It is used for furniture and cabinets where there is lower risk of damage with moisture presence.
What is BWP Plywood?
BWP stands for Boiling Water Proof plywood. BWP plywood is tested by soaking plywood in water for a long period of time. Like BWR plywood, it is prepared using high-grade hardwood veneers and phenol formaldehyde resin. The difference is that the intensity level and long term resistance of this type of plywood is significant. The resistance of BWP plywood can be tested when submerged in water, under running water, or even under boiling water. The use of BWP plywood is very much recommended for heavy-duty applications in moisture-rich environments, such as bathrooms and kitchens, furniture placed outdoors, and marine applications. The strength, termite resistance, and protection against harsh conditions makes it the best indoor and outdoor option for timeless furniture.
Key Differences Between BWR and BWP Plywood
It is very important to understand the difference between BWR and BWP plywood, especially while selecting the right material for your project.
Water Resistance Level
BWR can tolerate a bit of water and humidity but not continuous exposure to water. It can be used in areas that receive very less exposure to water and humidity. BWP plywood is highly resistant to water. It can sustain exposure to water for a long period of time. It is a go-to option for conditions where moisture or water would be in direct contact. Some examples of such applications include furniture in kitchens, bathrooms, boats and outdoor furniture.
Durability
BWR plywood offers good durability but warps or swells if exposed to water for a long time. It is generally preferred for indoor applications where exposure to water is almost negligible. BWP plywood has better durability due to its resistance to water, termites, and extreme environmental conditions. It is suited for heavy-duty applications wherein the long lasting solution is needed.
Application
BWR plywood is used majorly for indoor applications such as cabinets, wardrobes, and other furniture that may not come in contact with water or moisture. BWP plywood can be used both inside and outside, be it marine plywood for boats, exterior furniture, or any kind of other construction which would be exposed to harsh moisture conditions. It also offers exceptional strength and durability to indoor furniture such as bed frames, shelves, wardrobes and kitchen cabinets.
Cost
BWR plywood is relatively cheaper as it has less resistance to water when BWR vs BWP plywood is compared.
Strength and Quality
Both types of plywood are strong; however, BWP is sturdier because of a good bonding process and materials. It can be used in very demanding locations requiring more robust material. BWR is good for light commercial applications but not for extreme conditions.
Benefits of using BWR Plywood
Affordable Water Resistance
For projects that need a minimum exposure to moisture, BWR plywood is the cost-effective solution. It offers water resistance at a relatively lower price than BWP plywood does.
For Indoor Application
BWR ply is used in indoor applications like cabinets and wardrobes where it offers resistance to humidity without full waterproofing.
Advantages of BWP Plywood
Complete water resistance
BWP plywood is ideal for indoors and outdoors. It is apt for water-exposed locations with constant wetting or exposure to water.
Strength and Durability
BWP plywood's durability ensures furniture and structures last for a long time. The resistance to termites and strength of BWP plywood enable them to be used well in residential or commercial environments.
Conclusion
Understanding the difference between BWR and BWP plywood is necessary to help one choose the right material for the project. One needs to decide depending on the project and budget.
Frequently Asked Questions
1. What is the primary difference between BWR plywood and BWP plywood? The key difference between BWR and BWP plywood is that BWR plywood has water resistance. It is not waterproof; however, the BWP is entirely waterproof and can be placed under direct exposure to water for a long time.
2. Can BWR plywood be used outdoors? BWR plywood is best used for indoor or semi-moist environments. BWP plywood should be used outdoors as it is highly resistant to water.
3. Is BWP plywood more costly compared to BWR plywood? BWP plywood is costlier due to the factor that it has more durability and water-proofing properties and high-grade material.
