Engineering Excellence
Architectural Precision & Heavy-Duty Performance for Overseas Procurement
Tejjsons manufactures premium aluminium casement windows and doors designed for international architects, real estate developers, and glazing importers. Built using architectural 6063-T5/T6 grade aluminium extrusions, our casement series delivers clean sightlines, structural integrity under high wind pressures, and effortless daily operation.
Unlike standard stock profiles, every frame is engineered directly from architectural CAD drawings. We specialize in two core system series — PS45 for sleek, high-strength openings and PS56 for heavy-duty, thermally broken, double-glazed facades. Both series comply with international performance and safety standards.
- High-grade 6063-T5/T6 alloy extruded for structural stability
- European multi-point shoot-bolt locking with stainless steel 304 friction stays
- Dual-seal EPDM gaskets providing airtight and watertight acoustic insulation
- Certified powder coating (60–80μm), PVDF, and anodised marine finishes

Technical Capabilities
Engineered Features for Demanding Building Envelopes
Our casement window and door systems undergo stringent quality audits to meet international standards for wind resistance, water tightness, and sound insulation.
Multi-Point Security Locking
Integrated European shoot-bolt hardware locks the sash into the frame at multiple points along the perimeter, providing high resistance against forced entry and tampering.
Airtight Weather Seals
Continuous dual EPDM compression gaskets and concealed internal drainage channels block wind-driven rain, dust storms, and ambient moisture, protecting indoor spaces.
Thermal Break Insulation
Polyamide thermal barrier strips separate internal and external aluminium profiles to drastically reduce heat conduction, lowering HVAC energy loads in air-conditioned buildings.
Custom CAD Fabrication
Every profile is cut and machined on precision CNC equipment. We issue complete shop drawings, glass schedules, and anchoring details for architect sign-off prior to production.
Export-Ready Packaging
Consignment units ship in custom steel-reinforced crates with corner protection. Insulated glass units travel in A-frame crates with detailed packing lists for smooth clearance.
System Benchmarks
Aluminium Casement Series Specification Matrix
Compare key technical parameters between Tejjsons PS45 and PS56 series casement systems. Custom glass and thermal configurations are calibrated per project requirement.
| Parameter | PS45 Standard Series | PS56 Heavy-Duty / Thermal Series | Engineering Impact |
|---|---|---|---|

System Typologies
Custom Opening Configurations for Every Architectural Layout
From classic French doors to advanced tilt-and-turn windows, we engineer casement hardware layouts matching exact spatial and ventilation requirements.
Side-Hung Casement Windows
Traditional outward or inward opening windows hinged along the vertical axis. Ideal for bedrooms and living rooms where clear sightlines and maximum ventilation are required.
Aluminium Casement Doors
Robust entrance and patio doors featuring heavy-duty hinges, low threshold seals, and multipoint locks. Designed to connect interior spaces smoothly with balconies, decks, and courtyards.
French Casement Windows & Doors
Dual-leaf opening systems without a central vertical mullion. When both sashes open wide, they leave a completely unobstructed panoramic opening for grand European aesthetic appeal.
Tilt & Turn Windows
Dual-action European mechanism allowing the window to tilt inward from the top for secure, rain-proof ventilation, or turn inward from the side for complete opening access and easy glass cleaning.
Top-Hung (Awning) Windows
Hinged at the top and opening outward from the bottom. Awning windows permit continuous airflow even during light rainfall, making them ideal for high-rise stairwells, restrooms, and commercial facades.
Bottom-Hung (Hopper) Windows
Hinged at the bottom and opening inward from the top. Popular in institutional developments, basements, and commercial spaces requiring controlled ventilation with enhanced child safety.
Surface Engineering
Durable Surface Coatings for Extreme Climates
Exterior window finishes must endure UV solar radiation, coastal salt air, and airborne pollutants without chalking or peeling.
Anodized Finish (15–25μm)
Electrochemical conversion coating that integrates into the aluminium alloy structure. Exceptional resistance to abrasion, scratch, and salt-mist corrosion with a metallic luster.
PVDF Fluorocarbon Coating
Advanced resin coating formulation recommended for tropical, humid, and beachfront environments. Delivers 20+ years of anti-fading color stability under intense sunlight exposure.
Wood-Grain Sublimation
Heat-transfer technology producing rich, natural timber aesthetics on structural aluminium profiles. Gives the organic warmth of real wood with zero warping, swelling, or maintenance.

Procurement FAQ
Frequently Asked Questions for Project Buyers
Technical, logistic, and performance queries answered directly for overseas project consultants and buyers.
Yes. Our aluminium casement windows deliver high acoustic attenuation due to their rigid multi-chamber profile geometry and continuous dual EPDM compression gaskets. When configured with double-glazed units (e.g., 6mm toughened + 12mm Argon spacer + 6mm laminated glass), noise levels are reduced by up to 42 dB, providing a quiet interior environment even in dense urban settings.
Yes. Constructed from 6063-T5/T6 architectural aluminium and treated with QUALICOAT-approved powder coating or 25-micron anodising, our systems will not rust, pit, or warp in saline coastal environments. Built-in pressure-equalized drainage slots prevent water ponding and leakage under heavy tropical rainstorms.
Security is integral to our profile design. Sashes are fitted with European multi-point shoot-bolt locking hardware that secures the panel into the outer frame at multiple locking points. Heavy-duty stainless steel 304 friction stays, anti-lift pins, and key-locking handles ensure robust protection against forced entry.
Every system is manufactured to custom project specifications. We work directly from your CAD architectural drawings to adjust profile depths, mullion reinforcement, opening styles, and frame colors (RAL colors, PVDF, anodised tones, wood grain). Glazing options include Low-E, reflective, tinted, Georgian bar, and smart privacy glass.
Profiles and assembled frames are wrapped in protective PE film, lined with thick foam corner guards, and packed inside fully enclosed, fumigated wooden crates. Glass units are packed separately in heavy-duty A-frame crates. Hardware schedules, installation manuals, and shop drawings are included in every container load for smooth site handling.
