Block Board

LEXI block board is manufactured with selected and seasoned planks. The planks are treated with preservatives of special quality to resist borer, termite and fungi attack and later kiln dried at a technically laid temperature schedule.

 

LEXI drying technology and temperature control parameters are tough to maintain elsewhere and rare in the industry but it superbly helps in getting balanced and straight planks.

LEXI boards are very suitable for Indian houses. These boards are available in MR and BWP grade for interior and exterior applications respectively.

LEXI block boards are best suited for load bearing horizontal panel applications. With a history of defect free boards,LEXI block board range is ideal to suffice any woodworking requirement.
