Choosing the correct aluminium window typology has a direct impact on ventilation, security, weatherproofing and the overall look of a building. Impala Fabricators guides every client, whether a homeowner, architect, contractor or interior fit-out company, toward the aluminium typology that matches the application.
Aluminium Casement Windows
Hinged aluminium windows for maximum ventilation
Aluminium casement windows are hinged on one side and open outward like a door, using a handle and multi-point locking arm. They are one of the most widely fabricated aluminium window systems supplied by Impala Fabricators because the design is simple, strong and cost-effective to fabricate and install.
Best applications: Kitchens, bathrooms, bedrooms, independent houses, and any room that benefits from full cross-ventilation.
Why it works: A fully open casement sash gives 100% of the window opening for airflow, better sealing against dust, noise and water than sliding systems, and works well with insect mesh — making it a dependable, budget-friendly aluminium window system for Kenyan homes and rental units.
Aluminium Sliding Windows
Space-saving horizontal glide windows
Aluminium sliding windows run on horizontal tracks, with panels sliding past each other rather than swinging open. Impala Fabricators fabricates sliding window systems with reinforced tracks and rollers for smooth, long-lasting operation, an important detail in Nairobi’s dusty environment.
Best applications: Balconies, apartments, high-rise units, rooms facing walkways or roads, and spaces where furniture or curtains would obstruct an outward-opening sash.
Why it works: Sliding windows do not need swing clearance, so they save usable space both inside and outside the room, are easy to operate at any height, and give a clean, modern aluminium window design that suits contemporary Nairobi apartments and office buildings.
Aluminium Tilt-and-Turn Windows
Two-in-one ventilation and cleaning window
Tilt-and-turn aluminium windows combine two opening modes in one sash: a small tilt from the top for controlled ventilation, and a full inward turn on side hinges for cleaning or emergency egress. Impala Fabricators fabricates and installs this typology using the additional hardware it requires.
Best applications: Premium apartments, upper-floor bedrooms, noise-sensitive rooms, and buildings where safe child-friendly ventilation and easy exterior-glass cleaning from inside are priorities.
Why it works: The tilt position allows secure, weather-protected ventilation even when a room is unoccupied, while the turn position allows both faces of the glass to be cleaned from inside — a genuine safety and maintenance advantage for multi-storey buildings.
Fixed Aluminium Windows
Non-opening windows for maximum light and insulation
Fixed aluminium windows are glazed directly into the frame with no opening sash. Impala Fabricators uses fixed panels either as standalone feature windows or combined with an opening casement or sliding section within the same frame.
Best applications: Staircases, double-volume living rooms, feature walls, office facades and high-rise buildings where the goal is daylight and view rather than ventilation.
Why it works: With no moving parts, fixed aluminium windows give the best air and water tightness of any typology, require the least maintenance, and create the cleanest, most contemporary aluminium and glass look for a facade.
