— FAQ
Frequently Asked Questions
While plywood consists of multiple thin veneers cross-landed together, WonderPly Platinum Blockboard is constructed using a solid, high-density core made of seasoned wooden rectangular blocks (filler strips) sandwiched between premium hardwood face veneers. It is engineered specifically for applications that require high structural stiffness, minimal bending over long lengths, and outstanding screw-holding capacity.
Yes, absolutely. WonderPly Platinum Blockboard is highly celebrated for its dimensional stability. The internal solid wood blocks are thoroughly seasoned in advanced kiln-drying chambers to match optimal moisture parameters. This uniform seasoning process, combined with precise cross-directional engineering, completely eliminates internal stresses, ensuring that long vertical panels like wardrobe doors and partitions remain 100% straight and warp-free.
Yes. WonderPly Platinum Blockboard is manufactured using premium, high-grade synthetic resins to achieve excellent moisture-resistant properties. It easily withstands ambient humidity shifts, steam, and minor moisture contact typical of modern residential layouts. However, for structural elements in direct, constant contact with pooling water (such as under-sink kitchen frameworks), we recommend combining it with our certified IS 710 Boiling Water Proof (BWP) WonderPly Club or Platinum plywood lines.
