What are the standard sizes and thicknesses of coir veneer board?

Standard sizes are 2440x1220, 2140x1220, 1840x1220 mm etc. and thicknesses are 3, 4, 6, 9, 12, 15, 18, 22 and 25 mm (Table 1).

What is the minimum required bending strength (MOR)?

The minimum Modulus of Rupture (MOR) is 20 N/mm² parallel to the face grain and 12 N/mm² perpendicular to it (Table 2).

Is this board waterproof?

The standard specifies requirements for water absorption but it is not inherently waterproof. For high moisture areas, a specific water-resistant grade using BWP type adhesive conforming to IS 848 should be used.

What is the minimum density specified for this board?

The board must have a minimum density of 600 kg/m³ (Clause 8.1).

This standard specifies the requirements for coir veneer boards, a composite material made from coir fibre, wood veneers, and synthetic resin adhesive. It covers materials, manufacturing process, dimensions, tolerances, and the physical and mechanical properties for general purpose applications like furniture, partitions, and interior paneling.

Practical Notes

Ensure the board is marked with the ISI Standard Mark for quality assurance.

This material provides good thermal and acoustic insulation properties due to its coir core, making it suitable for partitions.

For applications in damp environments like kitchens or bathrooms, ensure that a board bonded with BWP (Boiling Water Proof) type adhesive is specified and used.
