Interior-grade plywood sheets in a workshop

Boiling water resistant, interior grade

BWR Plywood

Boiling water resistant plywood marked to IS 303 — the working grade for dry and occasionally damp interiors, where a full BWP specification would be more than the location needs.

Specifying bwr plywood

What to know before you order

BWR sits between moisture resistant and boiling water proof. It handles the humidity of an ordinary Indian interior and the occasional splash, without the cost of a full phenolic marine specification.

For wardrobes, storage, general carcass work and wall panelling, this is usually the right grade. Step up to BWP only where water is genuinely present.

Panels in this group carry IS 303 marking with the grade and bonding type stamped on the sheet.
