PLY SUPPLY INC.

Common rules of thumb for furniture and cabinet work: 1/8" and 1/4" for backing panels, drawer bottoms, model-making, and laser cutting; 1/2" for drawer sides and light shelving; 5/8" for lighter cabinet boxes; 3/4" for cabinet boxes, furniture, structural work, and heavy shelving. Formwork and structural plywood use different thickness logic based on load and span. If you're unsure, describe your project in your quote request - we'll suggest the right thickness.

Formwork plywood is designed for pouring concrete - it has a film-coated face (usually phenolic film, brown or black) that releases cleanly from cured concrete and stands up to repeated reuse on construction sites. It's not intended for indoor furniture, cabinet, or food-contact applications: the coating and adhesives are formulated for industrial exterior use, not indoor air quality. If you need a plywood for furniture or interior work, look at our cabinet-grade or interior products.

Certification varies by product, supplier, and batch. If FSC or other chain-of-custody certification is required for your project, mention it when you request a quote and we'll confirm current availability and provide documentation.

It depends on the product. Cabinet-grade interior plywood in our lineup is generally suitable for indoor furniture and cabinet work. Formwork plywood and certain exterior/industrial products use phenolic resins and coatings that are not intended for indoor air applications - they're made for concrete formwork, exterior structures, or industrial use. If you need specific CARB Phase 2, E1, or similar certification for a regulated project (cabinets sold in California, school furniture, residential interiors, commercial regulated work), mention it in your quote request and we'll confirm what's compliant from current stock.

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.

Void-free core means there are no gaps or hollow spots between the inner veneer layers. This matters when edges will be visible or when you're doing precision cutting - voids cause weak spots, rough edges, and broken cutter bits. Baltic Birch and laser die boards are typically void-free. Products meant for hidden structural use may have looser core grades and can contain small voids. The product page describes the core type for each item.

The glue. Interior plywood typically uses melamine-based glue - strong and stable in dry indoor conditions, but not waterproof. Exterior plywood uses phenolic glue (often labeled WBP - Water Boiled Proof), which holds up to moisture, weather, and outdoor exposure. If your project will see rain, humidity, or any contact with water, choose Exterior. Application is listed on every product page.

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.

We carry a range of products for different applications - including cabinet-grade interior plywood, exterior and marine-grade plywood, laser die boards, formwork plywood for concrete pouring, and specialty boards. Browse the Products page to see what's currently available, or send us a quote request describing your project and we'll point you to what fits.

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.

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