Flooring-grade plywood can help prevent callbacks

Choosing flooring-grade plywood can help prevent callbacks in commercial and domestic flooring projects, according to International Timber, an importer and distributor of bespoke, sustainable timber and panel products.

Contract flooring specialists know that incorrectly specified plywood underlayment can result in swelling, peeling and lifting, even when other installation practices are correctly adhered to. Imagine installing a floor in a high-end commercial or residential setting, only to be called back to replace the underlayment as well as the floor itself, because the plywood used didn’t meet the grade.

Flooring-grade plywood features thicker face veneers to meet the recommendations of the Contract Flooring Association (CFA). International Timber’s flooring-grade plywood, for example, consists of thicker 1.2mm face veneers, compared to the 0.12mm found on some commercially available plywood.

In addition, BS 8203:2017 ‘Code of Practice for Installation of Resilient Floor Coverings’ recommends that flooring-grade plywood should have a glue bond of Class 3 Exterior. This also relates to test methods specific to plywood, in particular EN 314-2 ‘Plywood – Bonding quality – Part 2: Requirements (June 1993)’, which requires that the glue be able to stand up to a certain degree of moisture.

These certifications ensure that plywood is performing to the industry agreed standard of subfloor bases.

Craig Hewlett, Commercial Lead for Panel Products at International Timber, says: “Resilient contract flooring projects require the correct grade plywood to be fitted underneath. If the plywood sheets installed are not fit for purpose, meaning a lower-class glue or thinner face veneer, this can result in costly callbacks for flooring contractors, with lost time and money. We would always recommend that flooring specialists use flooring grade plywood for commercial and domestic projects for peace of mind.”
