When building or renovating a home, villa, hospital, or commercial complex, the doorframe (chaukhat) is the very backbone of your entryway. In India's varied climates—from the humid coastal plains to the heavy monsoon downpours and winter freezes of Uttarakhand and North India—traditional wooden chaukhats made of Sal, Teak, or Marandi wood often turn into expensive maintenance nightmares. They expand in humidity, jam against door shutters, rot from bathroom splashback, and fall prey to voracious termite (deemak) infestations.
That is why forward-thinking architects, civil engineers, and homeowners are replacing wood with Wood Plastic Composite (WPC) doorframes. And among all brands in the Indian market, Alstone Industries stands unchallenged as India's best and most reliable WPC chaukhat manufacturer.
In this complete 2026 price and technical guide, we break down the official WPC chaukhat price per running foot (RFT), compare ULTRA 1000 Density vs. NEO 850 Density, provide exact door frame cost calculations with our 35% project discount, and explain why Alstone WPC frames are the definitive lifelong choice for your property.

2. Why Alstone Is India's #1 WPC Chaukhat Manufacturer
While many local suppliers offer unbranded PVC or low-density composite sections, Alstone is recognized as India's gold standard for engineered WPC infrastructure. Here are the 8 undeniable reasons why architects, engineers, and builders trust Alstone above all others:
1. India's First & Best Govt-Approved WPC Manufacturer
Alstone is fully approved by major government building authorities including CPWD, MES (Military Engineer Services), State PWDs, and AIIMS. Over 1,800+ Alstone WPC doors and frames were supplied and successfully installed at the Government Medical College (GMC) Rudrapur project alone with a zero failure rate.
2. 100% Solid Extrusion (Zero Hollow Cavities)
Unlike cheap hollow PVC frames that warp under summer heat or shatter when bumped by furniture, Alstone chaukhats are 100% solid through-and-through. Available in 850 Density (NEO) and 1000 Density (ULTRA), they deliver the heavy, reassuring feel of natural solid wood without any of timber's organic defects.
3. 0% Water Absorption (Zero Monsoon Swelling)
Natural wood absorbs 15% to 30% water during monsoons, causing doors to stick, jam, and scrape the floor. Alstone WPC has 0.0% water absorption. It will never swell, rot, delaminate, or grow mold, making it the ultimate doorframe for bathrooms, terrace doors, coastal areas, and hill stations.
4. 100% Termite & Borer Proof for Life
Subterranean termites (deemak) cause billions of rupees in property damage across India every year, eating wooden chaukhats from inside out within 2 to 4 years. Alstone WPC contains zero cellulose for termites to digest, providing permanent, 100% termite and borer immunity without requiring toxic chemical sprays.
5. Exceptional Screw Holding Strength
Alstone's dense homogeneous polymer matrix provides exceptional screw withdrawal resistance. You can securely mount heavy 4-inch architectural stainless steel hinges and heavy flush or solid WPC doors without frame sagging or screw stripping.
6. 25-Year Manufacturer Replacement Warranty
Every genuine Alstone WPC doorframe is backed by an official 25-year manufacturer warranty against termite damage, water rot, and delamination, giving you complete lifetime peace of mind.
7. Precision Factory Rebates (Single & Double Rebate)
Alstone manufactures precision single rebate (SP) sections for standard doors and double rebate (DP) sections for entrance openings where you want both a heavy solid main door and an integrated mosquito wire-mesh door. No manual onsite rebate routing is required.
8. Factory Pre-Laminated & Paint-Ready Finishes
Available in pristine Frosty White, Natural Wood, or pre-laminated with luxurious woodgrain foils (Teak, Walnut, Dark Brown, Grey, Black). Alstone frames can also be PU painted, duco coated, or polished using standard wood paints.
3. Comprehensive Comparison: Alstone WPC Chaukhat vs. Wood & Other Materials
How does an Alstone WPC chaukhat stack up against traditional Sal wood, Teak wood, granite, and hollow PVC? The detailed engineering comparison below explains the significant cost, durability, and maintenance advantages:
| Feature / Parameter | Alstone WPC Chaukhat (ULTRA 1000) | Sal Wood Chaukhat | Teak Wood Chaukhat | Granite / Stone Frame | Hollow PVC Frame |
|---|---|---|---|---|---|

| Water & Moisture Resistance | 100% Waterproof (0% Absorption) | Absorbs water, expands & jams | Moderate water resistance, swells | 100% Waterproof | Waterproof but warps in heat |
| Termite & Borer Immunity | 100% Immune for Life | Vulnerable (needs chemical coats) | Naturally resistant, still risks attack | 100% Immune | 100% Immune |
| Monsoon Jamming & Warping | Zero Warping, Zero Jamming | High expansion & door rubbing | Moderate expansion | Zero expansion | High thermal bending & distortion |
| Screw Holding & Hinge Support | Excellent (Heavy 4" SS Hinges) | Good (when well-seasoned) | Excellent | Requires special nylon plugs / brackets | Poor (screws strip easily) |
| Maintenance & Polishing | Zero Maintenance (Pre-finished) | Repainting/polishing every 2-3 yrs | Regular polishing required | Zero polishing | Zero maintenance |
| Environmental Impact | 100% Eco-Friendly (Saves Trees) | Deforestation of natural forests | High deforestation impact | Heavy mining impact | Plastic waste |
| Manufacturer Warranty | 25-Year Warranty | No official warranty | No official warranty | No warranty | None or 1-2 years |
4. Single Rebate (SP) vs. Double Rebate (DP) Chaukhat: Which One Do You Need?
Understanding the rebate design is essential when ordering your doorframes:
Single Rebate Profile (SP)
Features a single pre-machined groove (depth 12-15mm) on one edge. Accommodates one single door shutter.
- Best For: Bedroom doors, bathroom/toilet doors, kitchen doors, interior study rooms.
- Popular Sizes: 100x50 mm, 75x50 mm, 125x50 mm, 125x62 mm SP.
- Net Cost: Lower cost per RFT (starts from ₹131.30/RFT after 35% discount).
Double Rebate Profile (DP)
Features two stepped grooves on opposite sides of the frame. Accommodates two independent shutters simultaneously.
- Best For: Main entrance doors, front gates, balcony doors requiring a solid wooden/WPC door + an outer wire-mesh (jali) mosquito shutter.
- Popular Sizes: 125x63 mm DP, 150x62 mm DP.
- Net Cost: Complete multi-functional solution (starts from ₹338.00/RFT after 35% discount).
5. Step-by-Step Installation Guide for Alstone WPC Doorframes
Installing Alstone WPC doorframes is clean, fast, and does not require specialized tools. Standard carpentry teams can complete an installation in 30–45 minutes using either of two standard methods:
Method A: Anchor Fastener & PU Foam (Recommended for Finished Openings)
1. Mitre Joint Assembly: Cut the top header and side jambs at a 45° mitre angle using a
standard mitre saw. Join corners securely with metal L-brackets and self-tapping SS screws.
2. Positioning & Levelling: Place the assembled chaukhat into the finished masonry opening.
Check plumb line, level, and diagonals with a spirit level and wooden shims.
3. Anchor Fastening: Drill 8mm holes through the frame into the brick/concrete wall. Fasten
with heavy-duty steel anchor bolts (3 fasteners per vertical jamb).
4. PU Foam Filling: Inject expanding Polyurethane (PU) foam into the gap between the chaukhat
and masonry wall. The foam expands to create an airtight, soundproof, and rock-solid bond.
5. Architrave Finishing: Once cured, trim excess foam and cover gaps with Alstone 50x12 mm
WPC architraves.
Method B: Traditional MS Holdfast Clamps (During Brick Masonry)
If installing during initial brick wall construction, screw standard galvanized MS holdfast clamps onto the back groove of the Alstone WPC chaukhat. As the brickwork rises, embed the holdfast clamps in 1:3 cement-sand mortar. Alstone's rear ribbed grooves ensure a mechanical bond with cement mortar.
6. How to Identify Genuine Alstone WPC Doorframes
Due to Alstone's market leadership, several unbranded suppliers sell cheap calcium-carbonate filled PVC frames under generic composite names. To ensure you receive 100% authentic Alstone products:
- Continuous Laser Hologram / Brand Print: Check for the official "ALSTONE" branding along the inner protective tape and side profile.
- Solid Core Density: Genuine Alstone frames have a solid, dense, ivory/frosty core with zero air pockets or brittle foam texture.
- Manufacturer Test Certificate: Demand an authentic test certificate and GST invoice from authorized dealer KR Glass and Plywood.
- 25-Year Official Warranty Card: Make sure your order is registered with the 25-year warranty seal.
