Sonear Block Boards are made of extra thick grade 'A' veneers and are filled with premium imported pine logs, cut out of central beams and composed core-stock of batons. They are fabricated from extra thick circular pieces of imported hardwood and long core veneers. They are bonded with Urea Formaldehyde under high pressure and temperature.

Cutting edge technology and special composing ensure that our boards are totally plain and uniform. Utmost care is taken to ensure no gaps, overlapping or corrugation which eliminates the chance of opening up of the board when cut. Sonear Block Boards are also totally resistant to termite, borer and other wood destroying organisms. They give exceptional strength and durability to your wall cabinets, cupboards, wardrobe and other furniture woodwork. Your carpenter will find it easy and hassle-free to work with them since they provide additional grip for screws and nails. These Block Boards are available in commercial and waterproof varieties for interiors as well as exteriors. Block Boards are available in Australian Pine wood and Poplar wood.
