1. General & Brand FAQs
WPC (Wood Polymer Composite) is an advanced composite material engineered from wood flour/fibers and thermoplastics. Unlike conventional timber or plywood, WPC provides unmatched long-term performance:
- 100% Waterproof & Termite-Proof: Zero risk of swelling, delamination, rotting, or pest infestation, even in constantly damp conditions.
- Fire-Retardant: Features self-extinguishing properties that enhance building fire safety.
- Maintenance-Free: Eliminates the need for recurring chemical pest treatments, polishing, or seasonal weatherproofing.
- Eco-Friendly & Sustainable: Prevents deforestation through the use of recyclable polymers and reclaimed wood fibers.
Authentic Alstone WPC doors, frames, panels, and decking can be sourced directly through authorized regional distribution at alstonewpchaldwani.in. We offer supply, technical guidance, and doorstep delivery across Dehradun, Haridwar, Rishikesh, Haldwani, Nainital, Almora, Rudrapur, Pithoragarh and the wider Uttarakhand region.
2. WPC Doors & Door Frames (Chaukhat)
Yes. Alstone WPC doors and door frames (chaukhats) are 100% impervious to water, humidity, and subterranean termites. They are engineered to endure heavy water splash and high-humidity environments, making them ideal for bathrooms, kitchens, balconies, main entrance frames, and exterior perimeter entryways.
While the upfront investment of a WPC door or frame is on par with premium flush doors, WPC delivers superior lifetime cost efficiency. Traditional wooden and flush doors require ongoing painting, polishing, and pest protection, and remain vulnerable to seasonal warping and dampness. WPC doors offer a lifespan exceeding 25+ years with practically zero recurring maintenance expenses.
Yes. Alstone WPC surfaces can be customized with PU polish, DUCO paints, PVC decorative foils, or standard high-pressure laminates (sunmica). In addition, solid WPC sheets allow precision CNC routing and 3D decorative groove carving without surface chipping or structural degradation.
3. WPC Wall Panels & Louvers
WPC interior fluted panels and exterior louvers are widely used for feature walls, TV console backdrops, ceiling paneling, and exterior building elevations. They feature tongue-and-groove interlocking profiles that allow clean, fast installation directly onto plastered masonry or sub-framing using standard hardware and specialized adhesive.
Yes. Exterior-grade WPC wall claddings are formulated with UV-stabilizers and weather-resistant additives. They perform exceptionally well in high-rainfall and temperature-fluctuating environments across Uttarakhand, resisting warping, color fading, cracking, and moisture absorption.
4. WPC Outdoor Decking
Natural timber decks demand regular sanding, protective oiling, and chemical sealing to prevent rotting and splinters. Alstone WPC outdoor decking provides key operational advantages:
- Splinter-Free & Anti-Slip: Safe and comfortable for barefoot walking around swimming pools, garden paths, and balconies.
- Resistant to Mold & Algae: Non-porous surface prevents slippery organic growth and UV degradation.
- Integrated Drainage: Profiled drainage grooves facilitate fast rainwater runoff.
High-density Alstone outdoor WPC decking has an estimated service life of 15 to 25+ years in outdoor environments including rooftop lounges, open terraces, swimming pool decks, and commercial resorts without structural breakdown.
5. WPC Flooring
Laminate & Engineered Wood: Built with high-density fiberboard (HDF) or wood veneer cores that absorb water and swell under routine wet mopping or minor seepage.
WPC Flooring: Engineered with a 100% waterproof composite core, heavy-duty wear layer, and acoustic backing. It delivers authentic natural wood textures while remaining completely impervious to water warping, dampness, and termites.
6. Technical Specifications: Density, Thickness & Application Selection
Alstone WPC products are manufactured in precise density ranges (kg/m³) and thicknesses matched to specific structural demands:
| Product Category | Available Density (kg/m³) | Available Thickness | Best Application |
|---|---|---|---|
| WPC Door Frames (Chaukhat) | 850, 1000 | Standard profiles (Custom cut) | Heavy solid-core doors, main entrances, high-load structural frames |
| WPC Solid Doors | 550, 600, 660, 800 | 25mm, 30mm, 35mm | Bathrooms, bedrooms, commercial cabins, main entryways |
| WPC Panels / Boards / Sheets | 550, 600, 660, 800 | 6mm, 8mm, 12mm, 16mm, 18mm | Kitchen cabinets, CNC routing, TV backdrops, wall cladding, partitions |
Selecting the correct density and thickness ensures maximum screw-holding capacity, weight support, and longevity:
- For Door Frames (Chaukhat): Utilize 850 or 1000 density. This high-density range ensures solid wood-grade screw retention and eliminates frame sagging over decades.
- For Doors: 25mm to 30mm thickness (550–600 density) is optimal for bathroom and interior room doors. For high-traffic or main entry doors, choose 30mm or 35mm (660–800 density).
- For Modular Kitchens & Wardrobes: Choose 16mm or 18mm sheets (600–800 density) for structural cabinet carcasses and shutters to maintain rigid weight-bearing capacity.
- For Wall Paneling & CNC Jali Work: Use 6mm, 8mm, or 12mm panels (550–660 density) for lightweight decorative paneling and intricate CNC geometric patterns.
7. Quality Assurance: Warranty & Screw-Holding Capacity
Alstone WPC doors, frames (chaukhats), and boards are backed by a 25-Year Guarantee against 100% water damage, termite attacks, borers, fungal decay, and seasonal warping. This makes them a completely worry-free, lifetime investment for both residential and commercial infrastructure across Uttarakhand.
Alstone high-density WPC products feature 100% Solid Screw-Holding Capacity comparable to natural solid timber and superior to hollow composites or low-grade particle boards. With density ratings reaching up to 800–1000 kg/m³, standard wood screws and heavy-duty stainless steel hinge fasteners grip firmly into the core without thread stripping or loose hinges over repeated cycles of opening and closing.
