In construction, WBP plywood is extremely popular because of its properties. In this post, we explore this particular type of plywood and its benefits.

What does WBP stand for?

“WBP” means “weather and boil-proof”. This is a type of plywood where the glue line will not get damaged during periods of wet weather, nor will it have any issues if exposed to regular boiled water.

The glue line on other types of plywood don’t have this benefit, but this is what makes WBP plywood so popular in construction.

What is WBP plywood used for?

As we’ve mentioned, it’s mainly used in construction. The properties of the plywood make WBP plywood the perfect type to be used for outdoor projects or for exterior home improvements.

It’s very common for WBP plywood to be used for outdoor sheathing. Because of its weather resistant properties, construction workers prefer using WBP plywood to other types of plywood that would not be able to stand up to adverse weather conditions.

WBP plywood is not to be confused with Marine plywood. Although they are almost the exact same type of plywood, Marine plywood is superior in the sense that it will not show any knotholes and will never have cracks in the wood. In comparison, WBP plywood may have these imperfections.

Can WBP plywood get wet?

Indeed, it can! Because it’s both weather-proof and boil-proof, WBP plywood has the ability to withstand bad weather (such as rain and snow), boiling hot water, and be splashed without an onlooker seeing any difference.

A major benefit of WBP plywood is that it can get wet and be dried multiple times, and the owner will still see the same plywood. There should be no delamination if it is true WBP plywood.

I’ve heard it doesn’t exist

This certainly isn’t true! Both WBP plywood and Marine plywood are available from numerous suppliers across the construction market. Many professionals that work in construction and/or home improvements will likely be offered WBP plywood several times over the course of their career.

The name of the plywood actually refers to the type of adhesive that was used in its making.

Is there a difference between structural plywood and WBP?

There are a few differences between structural plywood and WBP plywood. The most obvious one is the WBP aspect of WBP plywood – that being that it can get wet and withstand boiling water.

You could easily use WBP indoors where there might be incidences with boiling hot water and you won’t have any issues if the water were to spill onto your WBP plywood floor or furnishings.

Some household owners have noticed that the hardwood face of WBP plywood has a better finish that structural plywood.

You will, of course, need to ensure that whatever plywood you choose to use is up to code before agreeing to purchase it for your project.
