The quality of plywood for countertop construction directly impacts durability, structural strength, and resistance to moisture and damage. Royale Touche's comprehensive guide will help you understand:
- Which type of plywood for countertop is ideal
- The different plywood for countertop options available
- Helpful tips on how to choose plywood for countertop for your next project
Royale Touche Plywood Recommended for Countertops
Boiling Waterproof (BWP) Plywood
Boiling Waterproof plywood is uniquely manufactured to withstand lots of moisture and has natural properties to prevent fungal punctured growth and delamination at the surface. It is manufactured with hardwood veneers, and glued using phenol formaldehyde resins, and retains its dimensional stability under long wet exposures. With a sturdy core material and nearly zero warping, it can support heavy granite, quartz or laminate kitchen countertop finishes. With Royale Touche's higher quality BWP, expect superior long-term resistance to normal stains and moisture from spills in high-use areas.
Best suited for: Kitchens, bathrooms, outdoor counters
Calibrated Plywood
Calibrated plywood is made by precisely sanding sheets to a uniform thickness. This sanding offers a flat and uniform material for flawless layering of laminates and other surface materials, and allows fast and accurate installation without the need for heavy surface correction. The well-prepared, smooth, and even surface also reduces the additional finishing required. When you use Royale Touche calibrated plywood, you can be assured of unparalleled accuracy, which is particularly effective when building modular systems or providing accuracy in designer-driven interior spaces, with minimized waste, and a clean, professional finish.
Best suited for: Modular kitchens, designer countertops
Hardwood Plywood
Hardwood plywood is manufactured using dense hardwood species (such as Gurjan) that yield maximum strength, superb screw-holding capacity, and structural durability. Its capability to support heavy loads without sagging or twisting makes it a great choice when your project warrants durability and performance. Royale Touche hardwood plywood's construction style consists of layers to withstand pressure, constant use, and often fluctuating temperatures, a considerable advantage to those with a commercial kitchen, or with children in their kitchen.
Best suited for: Traditional countertops, commercial counters
Water-Resistant Plywood
Water-resistant plywood is made using melamine adhesive which provides a level of resistance to occasional water splashes and moisture in less exposed areas. It is also less expensive than BWP yet can perform well in dry-wet transition areas. The Royale Touche's water-resistant plywood offers strength and stability and prevents water from causing swelling or warping over time. It is an excellent mid-range option for interior plywood for countertop on which you may have light water use.
Best suited for: Semi-wet areas, near sinks
Moisture-Resistant (MR) Plywood
Moisture-resistant (MR) plywood has been developed for interior usage where moisture is expected in high humidity, but not direct water contact. MR plywood is laminated using urea-formaldehyde glue, allowing abatement of warping due to ambient moisture in areas like kitchens, laundry rooms, or storage rooms. Royale Touche offers MR plywood that is dimensionally stable and easy to machine, making it an excellent substrate for products, such as plywood for countertops, in controlled environments.
Best suited for: Bath vanities, utility areas
Termite-Resistant Plywood
Termite-resistant plywood is produced using a chemical treatment in which a chemical is applied to the plywood after the plywood has been manufactured to allow it to be protected from damage by termites and wood borers. Pests have the tendency to eat their way through the inner layers of a plywood for countertop bases inside kitchens or cabinetry, causing a severe loss of structural integrity or hygiene. Royale Touche offers termite-proof plywood to ensure long-term protection that maintains the structure and hygiene of your installation for as long as possible, especially in humid or tropical regions.
Best suited for: Kitchens, pantries, tropical locations
Fireproof Plywood
Fire retardant plywood is first treated with flame retardants that will delay ignition and help reduce the spread of fire - providing important protection in a high-temperature area. Fire-rated plywood will maintain its structural integrity longer than untreated plywood if a fire occurs, thus helping to prevent sudden collapse. Royale Touche's fire-rated plywood is the perfect material for sensitive installations, where safety and fire rating should never be compromised, without compromising the design aesthetic.
Best suited for: Commercial kitchens, high-risk areas
Gurjan Plywood
Gurjan plywood is a type of structural plywood available that utilizes high-quality Gurjan hardwood, and is sought for its density, strength, and extreme durability. Gurjan plywood is possibly one of the most reliable materials for plywood for countertops that get heavy use. Gurjan plywood will resist bending, cracking, and mechanical wear, and it can be installed even in high-span applications and commercial projects. Royale Touche Gurjan plywood offers a solid, durable base for high-performance plywood for countertop builds.
Best suited for: Commercial-grade countertops, heavy-span counters
