Why Choosing the right Plywood Matters
All plywoods are not equal, particularly in areas of high humidity. Whether you are renovating the bathroom or building an outdoor kitchen, the decision between commercial plywood and marine plywood matters. Having the proper plywood provides structural integrity, durability, and a greater return on investment.
With the growing need for water-resistant interiors, it’s important to know the right types of plywood used in residential construction to save on repair expenses in the future. Here, we’re going to compare their water-resistance, price, longevity, and learn about the advantages of marine plywood for wet areas.
What is Commercial Plywood?
Commercial plywood or MR (Moisture Resistant) plywood is a common material employed in indoor carpentry. It consists of a few layers of wood veneers glued together with the help of urea-formaldehyde resin. Even though it is appropriate for dry areas, it cannot be said to be waterproof plywood for bathroom or kitchen use.
Key Features:
- Made using MR-grade resin
- Available in multiple thicknesses
- Cost-effective option for interiors
Best Uses:
- Bedroom and living room furniture
- Cupboards in dry areas
- Partitions and decorative panels
It is ideal for low-moisture areas but is not recommended as plywood for wet areas due to its low water resistance.
