Plywood is a versatile and popular building material used for everything from furniture to internal walls. But with so many different types available, choosing the right one can be confusing.
Two common types you’ll encounter are MR and BWR plywood, and understanding the difference between them is crucial for making an informed decision for your project.
What is MR Grade Plywood?
MR, or Moisture Resistant plywood, is a basic grade plywood suitable for indoor applications with moderate moisture exposure. It uses urea formaldehyde resin as a bonding agent, making it more resistant to warping and swelling than unprocessed wood.
Benefits of Choosing MR Grade Plywood
Cost-effective: MR plywood is a budget-friendly option compared to higher moisture-resistant grades.
Wide availability: MR plywood is readily available at most hardware stores.
Suitable for most indoor applications: Perfect for furniture construction, cabinets, wall panelling, and other projects in dry or low-moisture environments.
Applications of MR Plywood
Interior furniture: Cabinets, bookshelves, wardrobes, and other furniture pieces that won’t be in direct contact with water.
Partitions and wall panelling: This is used to create interior walls and partitions in dry areas.
Ceiling applications: Suitable for indoor ceilings that won’t be exposed to excessive humidity.
What is BWR Grade Plywood?
BWR, or Boiling Water Resistant plywood, is a step up from MR in terms of moisture resistance. It utilizes phenol formaldehyde resin as a bonding agent, making it significantly more resistant to warping, swelling, and even boiling water exposure.
BWR plywood is also treated with chemicals to improve its resistance to termites and borers.
Benefits of Choosing BWR Grade Plywood
Superior moisture resistance: Ideal for applications with higher moisture exposure, like kitchens, bathrooms, and laundry rooms.
Increased durability: BWR plywood is more resistant to warping, cracking, and insect damage compared to MR plywood.
Versatile for various applications: Suitable for both indoor and outdoor applications.
Applications of BWR Plywood
Kitchens and bathrooms: Cabinets, countertops (with proper waterproofing), and wall panelling in moisture-prone areas.
Laundry rooms: Cabinets and wall panelling for areas with frequent humidity fluctuations.
Outdoor furniture (with proper protection): Can be used for building outdoor furniture with regular maintenance and proper sealing.
MR vs BWR Plywood: Understanding the Key Differences
Here’s a quick breakdown of the key difference between BWR and MR plywood:
| Feature | MR Plywood | BWR Plywood |
|---|---|---|
| Moisture Resistance | Moderate | High |
| Bonding Agent | Urea-formaldehyde | Phenol formaldehyde |
| Termite & Borer Resistance | Lower | Higher |
| Cost | Lower | Higher |
| Applications | Dry or low-moisture interiors | Moderate to high-moisture environments |
Wrapping Up
Choosing between MR and BWR plywood depends on your project’s specific needs. MR plywood is a cost-effective option for dry interiors, while BWR plywood offers superior moisture resistance and durability for kitchens, bathrooms, and other high-moisture areas.
By understanding the difference between BWR and MR plywood grades, you can select the right plywood for your project and ensure a long-lasting, successful outcome.
