Certified Quality and Grade OptionsOur blockboards are IS:1659 certified, available in MR and BWP grades for optimal performance. The MR grade is formulated with Urea Formaldehyde (UF) resin, offering reliable moisture resistanceideal for indoor applications. The BWP grade employs Phenol Formaldehyde (PF) resin, allowing panels to withstand 72 hours in boiling water, ensuring robust protection in humid or wet settings. Both are hot pressed for consistent bonding and feature precise dimensional tolerances.
Construction and Core FeaturesThe blockboards sturdy core consists of hardwood frames with Pine or Poplar wood battens, resulting in less than 1mm core gaps as per IS standards. Face veneers range between 0.5mm and 1mm thick, and all surfaces are smooth and sanded for hassle-free finishing. Chemically treated cores ensure resilience against termites and borers, making the panels suitable for demanding environments.
Customization and VersatilityCustomers can opt for various sizes (8x4 ft, 7x4 ft) and thicknesses (16mm, 19mm, 25mm), with custom dimensions and edge banding available on request. Compatible with flush doors, panel doors, and diverse swing or open styles, the blockboards fit furniture, doors, partitions, and a spectrum of interior applications. Design and lock handle positions are also customizable, optimizing ease of installation for manufacturers and suppliers across India.
FAQs of MR And BWP Grade Blockboard:
Q: How are MR and BWP grades of blockboard different in terms of water resistance?
A: MR (Moisture Resistant) grade blockboards use Urea Formaldehyde resin and resist occasional humidity, making them suitable for dry environments. BWP (Boiling Water Proof) grade blockboards employ Phenol Formaldehyde resin, allowing them to endure 72 hours in boiling water, ideal for areas exposed to high moisture or water contact.
Q: What process ensures uniform strength and bonding in these blockboards?
A: The boards are hot pressed, which guarantees uniform bonding between the core, battens, and veneers. This process not only improves structural rigidity but also enhances durability over time.
Q: When is it recommended to choose BWP grade blockboard over MR grade?
A: BWP grade is best selected for areas frequently exposed to high humidity or direct water, such as kitchens, bathrooms, or external doors. MR grade is suitable for interiors where occasional dampness may occur but regular water exposure isnt expected.
Q: Where can these blockboards be used effectively in construction or furniture making?
A: These blockboards are versatile, making them ideal for furniture, interior paneling, partitions, swing doors (flush or panel), and more. Their chemical treatment against termites and borers also allows them to be used in challenging environments.
Q: What benefit does the low formaldehyde (E1 class) emission provide?
A: Low formaldehyde emission, classified as E1, contributes to healthier indoor air quality by reducing harmful off-gassing, making these blockboards safer for homes, offices, and commercial spaces.
Q: How precise are the dimensions and what tolerances can be expected?
A: The blockboards meet exacting standards, with length and width tolerances within 5mm and thickness tolerance within 1mm, ensuring consistent sizing for seamless installation.
Q: What customization options are available for size, thickness, and finish?
A: Custom sizes and thicknesses (16mm, 19mm, 25mm) are available. Customers may also request edge banding, selection of surface veneers (Gurjan, Poplar, or as needed), and customization of design details like handle position and door style to suit various project requirements.
