Our Aluminium Works Services

Aluminium Curtain Walling

Curtain walling is the non-structural outer covering of a building, typically made of lightweight aluminium frames filled with glass. It creates striking, light-filled facades that define the modern skyline.

Commercial Curtain Walls: Floor-to-ceiling glass facades for office towers, banking halls, and showrooms. We design systems that accommodate thermal expansion and building movement.
Residential Curtain Walls: Feature glass walls for luxury homes, offering panoramic views of the Kampala hills or Lake Victoria.
Recreational & Hospitality Curtain Walls: Impressive lobby entrances for hotels and lodges, creating a dramatic first impression for guests.
Structural Silicone Glazing: A frameless aesthetic achieved by bonding glass directly to the aluminium substructure with high-performance silicone.

Our curtain walling systems are designed for:

Superior thermal performance, reducing the need for air conditioning.
Engineered drainage channels that prevent water ingress.
Accessible maintenance from the inside where possible.

Aluminium Partitioning

Aluminium partitioning divides interior spaces without the permanence of brick walls. It is ideal for creating private offices, meeting rooms, and defined zones within open-plan areas.

Office Partitioning: Floor-to-ceiling or partial-height aluminium framed glass partitions. We integrate blinds within double-glazed units for privacy on demand.
Commercial Banking & Retail Partitions: Secure teller screens and cash office enclosures with specified glass thickness for security compliance.
Industrial Office Partitions: Dividing administrative offices from noisy factory floors, with acoustic-rated glass for sound reduction.
Healthcare & Clinic Partitions: Clean, hygienic divisions for consultation rooms and waiting areas.

Benefits of our aluminium partitioning:

Rapid installation with minimal disruption to your operations.
Reconfigurable layouts if your space needs change.
Excellent natural light penetration, reducing electricity costs.
Professional, contemporary appearance.

Aluminium Projected Windows

Projected windows are hinged at the top or bottom and open outward, providing excellent ventilation while protecting the interior from rain. They are a popular choice across Uganda for their practicality and clean lines.

Top-Hung Projected Windows: Hinged at the top, these windows allow air circulation even during light rain, making them ideal for bedrooms and living areas.
Bottom-Hung Projected Windows: Hinged at the bottom, often used in stairwells and high-level applications where cleaning access from inside is required.
Commercial Building Ventilation: Banks of projected windows for office corridors and staircases to provide natural smoke ventilation in compliance with fire safety.
Industrial Ventilation: High-level projected windows in factory walls and warehouses to release hot air and fumes.

Our projected windows feature:

Smooth friction stays that hold the window open at any angle.
Multi-point locking for security.
Heavy-duty weather seals that block draughts and driving rain.
Compatibility with mosquito mesh screens.

Aluminium Fixed Glass Installations

Sometimes the best view is an uninterrupted one. Fixed glass installations provide large expanses of glazing that do not open, maximising natural light and scenery.

Residential Picture Windows: Framing a perfect view of your garden or landscape. We install large single panes or joined panels with minimal sightlines.
Commercial Shopfronts: Full-height fixed glass shopfronts that display your products to passers-by. We use toughened safety glass as standard.
Hotel & Lodge Viewing Panels: Panoramic fixed glass walls in guest rooms and restaurant areas, connecting interiors with the outdoors.
Industrial Glazed Screens: Fixed glazing in administration blocks overlooking factory floors for supervisory visibility.

Our fixed glass installations deliver:

Maximum daylight entry with minimal aluminium frame obstruction.
High-specification glazing options including tinted, reflective, or low-emissivity glass for solar control.
Robust fixing systems rated for wind loads and building movement.

Aluminium Sliding Doors and Windows

Sliding systems save space. They glide horizontally along tracks, meaning no floor area is needed for door swings. They are perfect for connecting indoor and outdoor living spaces.

Residential Patio Sliding Doors: Wide two-panel or three-panel sliding doors that open your living room onto a veranda or garden. We offer lift-and-slide mechanisms for heavy-duty panels.
Apartment Balcony Windows: Horizontal sliding windows that provide ventilation without protruding into walkways.
Commercial Shopfront Sliders: Robust sliding entrance doors for retail shops and supermarkets, designed for high-frequency daily use.
Hotel Room Balcony Access: Smooth, quiet sliding doors leading to private balconies. We use lockable handles for guest security.
Industrial Sliding Gates & Access Panels: Heavy-duty sliding solutions for vehicle and personnel access points within factory compounds.

Key features of our sliding systems:

Stainless steel tracks and rollers for smooth, silent operation.
Interlocking profiles that create a tight weather seal when closed.
Anti-lift security features on external doors.
Low-threshold options for wheelchair accessibility.

Aluminium Casement Doors and Windows

Casement units are hinged on the side and swing open like a traditional door. They offer the best air seal when closed and are among the most secure opening window types.

Residential Casement Windows: Classic side-hung windows for bedrooms, kitchens, and bathrooms. They open fully, allowing maximum breeze and easy external cleaning from inside.
Casement Entrance Doors: Single or double side-hung aluminium doors for main entrances and back doors. We incorporate robust multi-point locking systems.
Commercial Office Casements: Durable casement windows for individual offices that require full ventilation control.
Recreational Casement Doors: Double casement doors opening onto pool decks or restaurant terraces, with panic bar hardware for emergency egress in public spaces.
Industrial Secure Casements: Heavy-duty, small-format casement windows for security-sensitive areas such as stores and plant rooms.

Our casement units provide:

The tightest compression seal when closed, offering excellent thermal and acoustic insulation.
Concealed or exposed hinges depending on the aesthetic requirement.
Compatibility with fixed fly screens and security grilles.
Long-term durability with minimal maintenance beyond occasional cleaning.

Reflective Glass: Mirrored coating for maximum privacy and solar rejection on commercial facades.
Low-E Glass: Microscopically thin coating that reflects heat while admitting light, improving energy efficiency.
Toughened Safety Glass: Heat-treated glass that is up to five times stronger than standard glass and shatters into small, blunt fragments if broken.
Laminated Glass: Two or more glass layers bonded with a plastic interlayer. It holds together when shattered, offering security and acoustic benefits.

Frequently Asked Questions

Are aluminium windows and doors more expensive than timber or steel?

Aluminium systems can have a higher initial material cost than timber, but they offer far lower lifetime costs. They do not rot, warp, or require repainting every few years. Compared to steel, aluminium is lighter, does not rust, and is easier to fabricate into complex profiles.

How long does fabrication and installation take?

This depends on the project scope. A standard residential installation of windows and doors typically takes two to three weeks from measurement to completion. Larger commercial curtain walling projects have timelines agreed upon during the quotation stage.

Do you provide a warranty on your aluminium works?

Yes. We provide a workmanship warranty on our installation and the system manufacturer’s warranty on the aluminium profiles and hardware. Specific warranty terms are detailed in your contract.

Can you replace old steel or timber windows with aluminium?

Absolutely. We regularly remove old window units and install new aluminium frames into existing openings. We take care to make good the surrounding walls and ensure a weather-tight seal.

Do you offer mosquito mesh screens?

Yes. We supply and fit durable aluminium-framed mosquito mesh screens for all our opening window and door types. These can be fixed or sliding to match the window operation.
