Overview
Tulsi Silver with Proclab is marked to the current IS 303:2024 revision under licence CML-9306574, supplied as grade MB — covering both MR and BWR — with the type stamped as BWR on the sheet.
The construction is zero-gap, full-core, full-panel with a 100% Gurjan face veneer. Zero gap means the core veneers are laid tight with no voids between them, which is what stops a screw from finding a hollow and what keeps a routed edge clean.
It is available in an unusually wide range of sheet sizes, including 2440 × 1830 mm and 2440 × 1600 mm, which is useful for wide panels that would otherwise need a joint.
