KPI Block Boards are made in Moisture Resistant & Boiling Water Proof Grade, duly bonded with Melamine Urea Formaldehyde & Fortified Phenol Formaldehyde Synthetic Resin respectively.
KPI block board is a premium quality board with high resistant properties against borer and termite attacks. All the three components of this block board i.e. Face Veneer, Core Veneer & wooden battens are well matched. The wooden battens are thoroughly seasoned in scientifically run seasoning kiln plants and then cut with great precision to obtain uniform thickness.
These battens are systematically arranged and utmost care is taken to avoid any extra gap between the battens. Regular tests are conducted to maintain the quality of block boards as per the standard IS: 1659.
