Complete Guide to Jindal Aluminium Domal Windows & Doors: 27mm, 35mm, 40mm Series Comparison, Weight & Pricing
In the realm of modern residential and commercial fenestration, the term "Domal" has become synonymous with premium European-engineered aluminium windows and sliding door systems. Unlike standard local 18mm or 27mm sliding profiles that rattle in high winds, leak rainwater during monsoons, and provide negligible acoustic insulation, Italian-origin Domal architectural systems are engineered specifically for monumental glass expanses, effortless gliding, hermetic weather-tightness, and superior acoustic decoupling.
Across premium residential enclaves, high-rise luxury apartments, and corporate offices in Delhi NCR, Gurgaon, and Noida, architects consistently specify Jindal Aluminium Domal sections to deliver structural reliability and enduring luxury aesthetics.
Curated by the technical fenestration specialists at Premier Aluminium Traders (authorized stockist and distributor for Jindal Aluminium Limited in Paharganj, New Delhi since 1978), this comprehensive engineering and procurement guide breaks down everything you need to know about Jindal Domal systems—including structural anatomy, 27mm vs. 35mm vs. 40mm series comparisons, profile weight charts, acoustic benchmarks, glass configuration limits, and commercial BOQ costing.
1. What Are Domal Aluminium Systems and Why Do They Outperform Standard Profiles?
Originating in Italy, the Domal design philosophy was conceived to address the fundamental structural shortcomings of conventional box-section sliding windows. Standard commercial window profiles are typically single-chambered, feature shallow track depths, and rely on basic nylon rollers that degrade under the dead weight of modern high-performance glass.
In contrast, Jindal Aluminium Domal sections are extruded from high-purity Alloy 6063-T6 primary aluminium billets (conforming to IS 733 and ASTM B221 standards) and incorporate several proprietary structural innovations:
- Multi-Chamber Structural Rigidity: The profile cross-sections feature internal stiffening webs and reinforced hollow chambers that provide exceptional Moment of Inertia ($I_x, I_y$). This enables fabricators to erect tall sliding shutters (up to 3.0 to 3.5 meters high) without noticeable sash flexing under wind pressures.
- Precision Gutter Drainage Systems: Domal outer frames incorporate a calibrated sill slope with stepped internal drain pockets and one-way flap valves. Even during intense torrential monsoon downpours characteristic of North India, water drains rapidly outward via gravity without back-flowing onto interior sills or wooden floorings.
- Continuous EPDM Gasket & Wool-Pile Interlocks: Instead of rudimentary rubber seals, Domal profiles integrate dual-fin silicone-treated wool piles and heavy-duty co-extruded EPDM gaskets into dedicated extrusion dovetails. This blocks air infiltration, fine PM2.5 dust, and external traffic rumble.
- Heavy-Duty Stainless Steel Track & Tandem Rollers: The bottom outer rail houses an extruded stainless steel (SS 304) guide track. Shutter panels glide on adjustable tandem nylon or SS ball-bearing rollers rated to support glass panel loads exceeding 150 kg to 250 kg per sash with whisper-quiet, feather-touch movement.
2. Technical Anatomy of a Domal Sliding Window & Door Assembly
A genuine Jindal Domal window system is composed of several precision-matched architectural extrusions that interlock to form an integrated weather-proof envelope:
+-------------------------------------------------------------+
| Top Outer Frame (Track) |
+-------------------------------------------------------------+
| [Glass Panel] | [Interlock Sash] | [Glass Panel] |
| (Double Glazed) | (Reinforced Fin) | (Double Glazed) |
| | | |
| [Handle Profile]| [Wool-Pile Seal] | [Lock Profile] |
+-------------------------------------------------------------+
| Bottom Outer Frame with SS 304 Inlay Rail |
| + Calibrated Stepped Drainage Chambers |
+-------------------------------------------------------------+
Core Extrusion Components:
- Outer Frame (Track Section): Available in 2-Track, 3-Track (accommodating an independent stainless steel mosquito mesh sash), and 4-Track multi-slider configurations. Frame depths range from 65mm up to 142mm.
- Shutter (Sash Section): The operable perimeter frame holding the glass. Domal shutters feature deep glazing pockets (up to 24mm to 32mm) designed to accommodate single toughened glass (6mm–8mm) or hermetically sealed Double Glazed Units (DGU - 5mm + 12A + 5mm).
- Interlock Section: The vertical vertical profile where sliding panels overlap. Domal interlocks are fortified with structural aerodynamic stiffeners to prevent air whistling and structural deflection during high-velocity storm gusts.
- Glazing Beads: Snap-in interior clips with integrated gasket channels that securely lock the glass unit without visible external fasteners.
3. Comprehensive Comparison: 27mm vs. 35mm vs. 40mm Domal Series
Choosing the correct Domal series is dictated by panel dimensions, wind-load exposure (floor height), and whether single or double glazed units are specified:
| Engineering Parameter | Domal 27mm Series | Domal 35mm Series | Domal 40mm Heavy-Duty Series |
|---|---|---|---|
| Profile Sash Depth | 27 mm | 35 mm | 40 mm – 45 mm |
| Primary Alloy & Temper | 6063-T6 (IS 733) | 6063-T6 (IS 733) | 6063-T6 / 6082-T6 |
| Max Recommended Shutter Height | 2.1 m (7.0 ft) | 2.6 m (8.5 ft) | 3.2 m – 3.6 m (10.5 – 12 ft) |
| Max Shutter Width | 1.0 m (3.3 ft) | 1.4 m (4.6 ft) | 1.8 m (6.0 ft) |
| Glazing Pocket Thickness | 5 mm – 12 mm | 8 mm – 20 mm | 20 mm – 32 mm (DGU / Laminated) |
| Max Panel Load per Sash | Up to 80 kg | Up to 140 kg | Up to 250 kg (Tandem SS Rollers) |
| Design Wind Load Resistance | Up to 1.2 kPa ($120\text{ }km/h$) | Up to 1.8 kPa ($155\text{ }km/h$) | Up to 2.5 kPa ($185\text{ }km/h$) |
| Typical Architectural Application | Standard bedroom windows, utility balconies | High-rise apartments, living room balconies | Luxury villa walk-outs, penthouses, monumental facades |
| Approx. Profile Weight (Sash/Track) | $0.85 - 1.15\text{ }kg/m$ | $1.25 - 1.65\text{ }kg/m$ | $1.85 - 2.60\text{ }kg/m$ |
Which Series Should You Specify?
- Choose the 27mm Series for economical residential window upgrades, internal courtyard dividers, or low-rise apartments where panel heights remain below 7 feet and standard single toughened glass (6mm/8mm) is sufficient.
- Choose the 35mm Series as the standard workhorse for modern high-rise apartments (floors 5 to 25) where wind resistance, double-glazed acoustic isolation, and panels up to 8.5 feet high are required.
- Choose the 40mm Heavy-Duty Series for grand monumental patio sliding doors, floor-to-ceiling balcony walkouts, luxury farmhouses in Chhatarpur, and penthouse elevations in Gurgaon exposed to severe wind drafts.
4. Jindal Domal Section Weight Chart & Theoretical Meter Calculation
To prepare an accurate Bill of Quantities (BOQ), fabricators and contractors must calculate profile weights based on standard mill extrusion densities ($\approx 2.70\text{ }g/cm^3$ or $2700\text{ }kg/m^3$). Below is an authentic reference guide for Jindal Domal profile weights:
| Section Description | Die Number Reference | Series | Theoretical Weight ($kg/m$) | Weight per 12ft Length ($kg$) |
|---|---|---|---|---|
| Domal 2-Track Outer Frame (Bottom/Top/Side) | JAL-D2T-01 | 27mm | 1.080 | ~3.95 kg |
| Domal 3-Track Outer Frame (with Mesh Track) | JAL-D3T-02 | 27mm | 1.540 | ~5.63 kg |
| Domal Sliding Shutter / Sash Section | JAL-DSS-03 | 27mm | 0.920 | ~3.36 kg |
| Domal Interlock Section (Standard) | JAL-DIL-04 | 27mm | 0.810 | ~2.96 kg |
| Domal Heavy Interlock with Reinforcing Fin | JAL-DHIL-05 | 27mm | 1.120 | ~4.10 kg |
| Domal 35mm 2-Track Heavy Outer Frame | JAL-35D-01 | 35mm | 1.480 | ~5.41 kg |
| Domal 35mm 3-Track Outer Frame | JAL-35D-02 | 35mm | 2.120 | ~7.75 kg |
| Domal 35mm Shutter Section | JAL-35D-03 | 35mm | 1.340 | ~4.90 kg |
| Domal 40mm Heavy-Duty 2-Track Frame | JAL-40D-01 | 40mm | 2.250 | ~8.23 kg |
| Domal 40mm Heavy-Duty 3-Track Frame | JAL-40D-02 | 40mm | 3.100 | ~11.34 kg |
| Domal 40mm Monumental Sash Profile | JAL-40D-03 | 40mm | 1.950 | ~7.13 kg |
| Snap-in Glazing Bead (DGU 24mm) | JAL-DGB-08 | Universal | 0.220 | ~0.80 kg |
Note: Weights listed represent raw mill finish extrusions. Anodized profiles add approximately 1.5% mass, while architectural powder-coated profiles add 2.5% to 4% depending on applied DFT (Dry Film Thickness, typically 60–80 microns).
5. Acoustic Performance & Thermal Insulation Metrics
Noise pollution and severe thermal swings are defining architectural challenges in Delhi NCR. Modern fenestration must create a quiet, energy-efficient interior sanctuary.
Sound Transmission Class (STC) & Decibel Reduction:
- Standard 18mm Single-Glazed Window: Provides merely $18 - 22\text{ }dB$ sound reduction. Street noise, honking, and construction easily penetrate the room.
- Jindal Domal 27mm with 6mm Toughened Glass: Achieves approximately $25 - 28\text{ }dB$ sound dampening.
- Jindal Domal 35mm / 40mm with 24mm DGU (6mm Glass + 12mm Argon Spacer + 6mm Acoustic Laminated Glass): Delivers phenomenal noise attenuation of $34 - 38\text{ }dB$. This reduces deafening arterial road noise ($80\text{ }dB$) down to library-like quiet ($42\text{ }dB$), fostering restful sleep and high productivity.
Thermal U-Value Performance:
When paired with solar-control Low-E (low-emissivity) double glazing, Domal framing systems drop the overall window assembly U-value from an inefficient $5.8\text{ }W/m^2K$ down to $1.8 - 2.4\text{ }W/m^2K$. This dramatically slashes recurring air-conditioning electricity loads during Delhi’s peak 45°C summer months.
6. Sourcing Genuine Jindal Domal Profiles vs. Local Counterfeits
Because Domal profiles command premium market value, unorganized markets in Delhi NCR frequently distribute lightweight, sub-standard imitation sections. These counterfeit profiles are melted from low-grade recycled scrap, suffer from uneven wall thickness, and lack proper T6 artificial aging.
How to Guarantee 100% Authentic Jindal Domal Profiles:
- Continuous Inkjet Laser Brand Markings: Genuine Jindal extrusions feature crisp, permanent factory markings printed at regular 1-meter intervals along the profile interior:
JINDAL - ALLOY 6063 - T6 - IS:733. - Standard Mill Test Certificate (MTC): Authorized distributors provide chemical spectrography and tensile test reports verifying proof stress $\ge 170\text{ }MPa$ and Webster hardness $\ge 12\text{ }HW$.
- Flawless Die Geometry: Sourced from precision computerized dies, authentic Jindal sections fit together with zero visible gaps at mitered joints and glide smoothly along the tracking channel.

8. Frequently Asked Questions (FAQs)
1. What is the main difference between Domal windows and regular sliding windows?
Regular sliding windows usually feature shallow 18mm or 27mm non-engineered tracks, thin wall extrusions (under 1.0mm), and exposed drainage gaps. Domal windows are heavy-duty multi-chambered architectural systems with wall thicknesses between 1.4mm and 2.2mm, stepped internal drainage channels, continuous EPDM seals, and compatibility with heavy double-glazed units and multi-point security locking systems.
2. Can I install a mosquito mesh track on Jindal Domal sliding windows?
Yes. Jindal Domal outer frames are available in 3-track configurations specifically engineered to integrate an independent sliding sash fitted with high-tensile SS 304 black wire mesh or pleated mesh, providing full insect protection without compromising natural ventilation.
3. What surface finishes are recommended for Domal profiles in Delhi's climate?
Due to high atmospheric particulate levels and intense UV radiation in North India, we recommend either:
- Architectural Anodizing (15 to 25 microns): Natural Silver, Champagne, Bronze, or Black finish. Highly scratch-resistant and UV-stable.
- Qualicoat Class 1/2 Powder Coating (60 to 80 microns DFT): Available in hundreds of RAL shades with matte, satin, or fine-textured finishes.
- Sublimated Wood-Grain Finishes: Provides the rich, warm appearance of natural teak or walnut with zero maintenance and zero termite risk.
4. Which glass thickness is best suited for 35mm Domal sliding doors?
For balconies and high-rise apartments, a 24mm Double Glazed Unit (DGU) consisting of 6mm Outer Toughened Glass + 12mm Argon Air Gap + 6mm Inner Toughened / Laminated Glass is ideal. This setup provides optimum thermal insulation, resists severe wind loads, and blocks up to 36 dB of ambient traffic noise.
