Frequently Asked Questions

What styles and profile configurations of aluminium windows and doors do you engineer?

We supply an extensive portfolio of custom-engineered aluminium door and window systems tailored for high-end residential villas, commercial towers, corporate offices, and institutional developments. Our core system options include:

• Aluminium Sliding Windows & Sliding Patio Doors: Space-saving configurations equipped with heavy-duty stainless steel rollers, multi-point locks, and ultra-slim interlocking sightlines.
• Aluminium Bifold (Accordion) Folding Doors: Multi-panel folding systems designed to create seamless spans up to 10+ meters with flush threshold options.
• Aluminium Casement & Awning Windows: Top-hinged and side-hinged systems providing maximum weather seal performance, acoustic insulation, and controlled natural ventilation.
• Aluminium Jalousie & Louvered Systems: Adjustable and fixed louver blades engineered for optimal solar shading, airflow control, and privacy.
• Frameless Glass & Glass Swing Entrance Doors: Heavy-duty tempered glass entrance portals fitted with patch fittings, hydraulic floor springs, or concealed overhead closers.

Do you provide custom tailor-made dimensions and engineering shop drawings?

Yes. We do not restrict project designs to standardized modular sizes. Every structural aperture is laser-surveyed on site, verified against structural CAD drawings, and custom fabricated in our dedicated workshop.

Our engineering team assists architects, general contractors, and developers with custom extrusion profile selection, wind load safety calculations, drainage channel designs, and hardware specifications prior to mass fabrication.

Can architectural aluminium rust or corrode over prolonged environmental exposure?

No. Aluminium is intrinsically non-ferrous and cannot form red rust like steel or iron. Under ambient conditions, aluminium forms a natural self-passivating oxide film that protects against atmospheric corrosion.

To withstand severe UV radiation, high humidity, dust, and industrial pollution, we utilize certified Pak Alco and Chawla extrusion profiles treated with electro-anodizing (15-25 microns) or durable electrostatic powder coatings. This finish guarantees long-term color retention, salt-spray resistance, and zero structural chalking.

What is the engineering difference between rooftop glass railings and terrace glass railings?

While both systems prioritize safety and clear sightlines, they differ significantly in structural load design and environmental safety parameters:

• Rooftop Glass Railings: Installed at elevated heights subjected to severe wind suction forces. They utilize heavy-gauge continuous base aluminum U-channels, 12mm to 17.52mm toughened laminated safety glass (PVB/SGP interlayers), and stainless steel top caps to meet high-altitude structural safety codes.
• Terrace & Balcony Glass Railings: Designed for mid-level residential living spaces, utilizing side-mounted spigots, point-fixed standoff pins, or top-mounted channel profiles fitted with 10mm to 12mm single or laminated tempered glass.

Are aluminium architectural louvers effective at noise attenuation and solar heat reduction?

Yes. Properly engineered aluminium louvers serve as efficient solar and acoustic barriers. Aerodynamically angled louver blades dissipate direct thermal radiation before it reaches the building envelope, significantly lowering HVAC energy loads.

When specified alongside double-glazed insulated glass units (IGU) or acoustic laminated glass, louvered facade assemblies reflect external traffic and urban noise, ensuring a quiet interior environment.

Can overseas property owners and international contractors manage projects remotely?

Yes. A substantial portion of our client base comprises overseas Pakistanis, expatriate investors, and regional general contractors. We offer complete digital project management:

• Laser-surveyed site measurements and digital CAD shop drawings shared electronically.
• High-resolution material sample photos and video inspections of extrusion gauges and glass specifications.
• Mill test certificates for aluminium profiles and thermal temper certification for safety glass.
• Real-time progress tracking, workshop assembly videos, and full installation supervision on site.

What routine maintenance and care do aluminium glazing systems require?

Maintenance is minimal due to the inherent durability of high-grade architectural aluminium and tempered glass. Recommended maintenance includes:

• Washing profile frames and glass surfaces periodically with clean water and mild non-abrasive soap to remove airborne particulate matter.
• Clearing sliding track channels of dust and debris to prevent roller drag and seal wear.
• Inspecting EPDM weather gaskets, silicone perimeter seals, and lubricating mechanical lock gear boxes once or twice a year.

Do you provide after-sales support and replacement components?

Yes. Al-Karam Aluminium maintains a full inventory of replacement hardware, EPDM rubber gaskets, heavy-duty rollers, friction stays, floor springs, and locks. Our technical field support crew is available for recalibrations, glass replacement, or system upgrades.
