KEY FEATURES:
- Each layer of hardwood is chemically treated with such chemicals that Velva BWP provides immunity to microbes and bacteria.
- Velva BWP is both side calibrated to provide uniformity and precision in thickness of plywood.
- Velva BWP has a unique Quadra pressing manufacturing process
- Velva BWP provides 25 years warranty.
- Bonded with high solid content E1 grade Phenol formaldehyde based resin for long life and superior bonding.
- Each layer of hardwood veneer is stitched together by automatic core composers installed in the plant which provides no core gaps or Core overlaps.
- Velva BWP provides Gurjan face on both sides and is effectively resistant against borer and Termite.
