GSM material selection guide

MR, BWR, waterproof & fire-retardant plywood

Start with the exposure and performance your project needs, then select the exact product. Brand names, grade names and a photograph of a printed sheet are not interchangeable specifications.

Commercial MR plywood

For an MR requirement, compare products listed in GSM’s commercial range, including PROmac Classic MR, Prime Ply MR and Greenply Ecotec MR. Use each product page for its reviewed thicknesses, sizes and applications. MR means moisture resistant; do not treat it as a waterproof specification.

Water-resistant BWR plywood

PROmac Star BWR is listed in the water-resistant range. Compare its stated grade, core, adhesive and thickness against the project specification. A darker plywood face alone does not establish water resistance.

Waterproof and fire-retardant ranges

The waterproof selection includes PROmac Gold Waterproof, Furnfit BWP, Indomarine BWP and Greenply Ecotec 710. For a fire-retardant requirement, compare the separately listed iMac Club FR and Greenply Gold products. Waterproof and fire-retardant describe different requirements; use the exact manufacturer documentation for the selected product.

What to send for a useful quotation

Tell us what the panels will be used for and where the project is located. GSM can discuss the material and processing together.

  • Brand and exact product or grade required
  • Sheet thickness, dimensions and quantities
  • Application, exposure and any specified standard
  • Laminate finish, cutting sizes and edges to be banded, if required

Useful answers

Before you order.

Is waterproof plywood the same as fire-retardant plywood?

No. These are separate performance requirements. Select a product explicitly specified for the requirement and check its current manufacturer documentation.

Can I choose plywood by its colour or printed logo?

Use the product name, grade and reviewed specification. Colour and branding help identify a sheet but do not replace the specification or applicable manufacturer documents.
