Our Exterior Baltic Birch Plywood offers exceptional durability and aesthetic appeal for outdoor applications. These plywood sheets combine superior water resistance with the renowned strength and beauty of Baltic birch. Ideal for exterior sheathing, marine use, and outdoor structures, it provides reliable performance in demanding environments while maintaining a professional finish.

1/4″ Baltic Birch Exterior Plywood is suited for projects that require stronger moisture resistance than standard interior plywood. This exterior Baltic birch plywood is commonly used for exterior panels, signage, templates, curved components, protective covers, boat interior details, and lightweight outdoor-facing projects, while still offering the clean appearance and stability associated with birch plywood sheets. It is a practical option for contractors, builders, fabricators, and woodworkers who need exterior grade plywood for Canadian projects where durability, consistent thickness, and a smooth sanded surface matter.

 Trustindex verifies that the original source of the review is Google. Picked up a couple sheets of plywood.  Superior quality to big box stores and great prices.  Highly recommend checking them out next time you’ve got a project.

Another gem for a reno project.

Do you deliver across Canada?

Yes - we ship plywood anywhere in Canada from our Ontario warehouse. Most products are in stock locally and ready to go out as soon as your quote is confirmed.

Can I pick up my order in person?

Yes. Pickup is available at our Canadian warehouse and at our US warehouse in Newark, NJ. Let us know during the quote process and we'll arrange a time.

Why aren't prices listed on the site?

Plywood pricing moves with the global market. Supply costs, shipping rates, and exchange rates shift week to week - sometimes 10-15% within a few months. Posting a static price would either be outdated or force us to inflate it as a safety margin. Instead, we send you a personal quote with current pricing, so you pay what it actually costs today.

Do you offer volume discounts?

Yes. We offer discounts on full packages (bundles) of plywood. The number of sheets per package varies by product, so please call us to confirm the pack size, or simply submit a quote request and we'll sort it out for you.

Can I get a sample before ordering?

For large or recurring orders we can arrange samples on request. Send us a note about your project and we'll work something out.

Can I see your products in person before ordering?

Yes - both our Canadian warehouse and our US warehouse in Newark, NJ can accommodate in-person visits. Contact us first to arrange a time so the right person is available to show you stock.

Which plywood is right for my project?

It depends on three things: where the project will live (indoor, outdoor, in contact with water or concrete), whether the surface will be visible or hidden, and what tools you're using to cut it. Each product page lists the application (Interior, Exterior, Laser Cutting, Formwork, etc.) and grade. If you're not sure, describe your project in a quote request - we'll recommend the right product.

Can I use your plywood for CNC and laser cutting?

Some of it, yes - but not all. Products specifically suited for CNC and laser work need a void-free core, uniform thickness, tight grain, and clean machining behavior. We carry dedicated Laser Die Boards, and many of our Baltic Birch products work well for CNC. Formwork plywood, OSB, and some construction-grade products are not appropriate for laser or precision CNC. Tell us what machine you're running and what you're cutting when you request a quote - we'll recommend the right product.
