Types of Aluminium Windows

 

Choosing the right type of aluminium window is not simply about deciding between sliding and casement. The opening style affects ventilation, available space, daylight, security, cleaning and also the use of the room.

The most suitable aluminium windows for modern-day Indian homes are the ones that best fit the opening and its purpose. OKNA offers multiple aluminium window configurations, including sliding, awning, casement, parallel, tilt-and-turn, vertical, fixed and bi-folding window system.

Types of Aluminium Windows

Window Type	Opening	Ventilation	Suitable For
Sliding	Horizontal	Medium	Balconies, bedrooms
Casement	Hinged	High	Bedrooms, kitchens
Fixed	Non-opening	None	Views, staircases
Bi-fold	Folds & stacks	High	Large openings
Tilt & turn	Tilt or swing	High	High-rise homes
Awning	Top-hinged	Medium	Kitchens, bathrooms
Louvred	Angled slats	High	Utility areas
Combination	Mixed	Varies	Large window walls
Bay	Projects outward	Varies	Living rooms

The choice should consider ventilation, available clearance, glazing requirements and cleaning access.

Sliding Aluminium Windows

Sliding windows slide horizontally along tracks, so they're especially useful in situations where space is limited for an outward or inward opening.

Key benefits:

• Space-saving operation
• Suitable for balconies and apartments
• Smooth horizontal movement
• Available in different track configurations
• Can accommodate mosquito mesh systems

Generally, a 2-track system uses two shutters, while a 3-track system can accommodate a dedicated mesh shutter, if required.

Casement Aluminium Windows

These window types open outward or inward, operating on side-mounted hinges. When both ventilation and sealing are priorities, they are a strong choice.

Best suited for:

• Bedrooms
• Living rooms
• Kitchens
• Study areas
• Independent homes

The opening mechanism can provide large ventilation more than sliding windows and appropriate locking hardware may support security.

Fixed Aluminium Windows

Fixed windows do not open. Instead, they maximize the glazed area as much as possible to let in the light and views uninterrupted.

They work particularly well for:

• Feature walls
• Staircases
• High-level openings
• Living rooms
• Offices and commercial spaces

Depending on the system you choose, OKNA fixed windows will allow glazing from 5 mm single glass up to 32 mm for DGU.

Bi-Fold Aluminium Windows

Bi-fold windows consist of number of connected panels that fold and stack to one or both sides for a wide opening.

They are particularly suitable for:

• Large balconies
• Wide view-facing openings
• Servery counters
• Indoor-outdoor connections

As the panels need to be stacked and require additional hardware, the opening should be planed accordingly.

Tilt & Turn Aluminium Windows

Tilt & turn windows do both functions in one single system. The sash can tilt to one side for a controlled airflow, or turn on its side for a wider opening.

Advantages include:

• Flexible ventilation
• Convenient cleaning access
• Multi-point locking possibilities
• Suitable for high-rise applications
• Controlled ventilation for spaces that need extra protection

OKNA offers tilt & turn aluminium system windows as part of its architectural window range.

Awning, Louvred & Ventilator Windows

They are hinged at the top and open out from their base. They can be useful for a kitchen, bathroom and high-level openings where controlled ventilation is required.

Louvred and ventilator windows consist of angled slats or compact ventilator pieces, allowing to maintain airflow. They are often used for bathrooms, utility spaces, staircases and exhaust-fan openings.

Combination & Bay Aluminium Windows

Combination window brings together various configurations into a single window, like fixed glazing with sliding or casement sections. It can also be said that it is used for larger openings where both day light and ventilation are required.

A bay window projects outward and can have both fixed and operable sections, efficiently extending the view-lines even further.

Aluminium Window Sections and Profiles

The window type is the way the window functions and the section is an aluminium profile system that builds the product.

Common considerations include:

• 2, 3 or 4-track sliding sections
• Hinged & locking hardware-based casement sections
• Slim profiles for bigger glass sizes
• Heavy duty profiles for larger spans & more demanding applications
• Thermally improved systems, which focus on improved insulation

This is why selecting an experienced aluminium window manufacturer in India matters. The profile should be chosen according to the wind load, opening, glass and purpose.

Glass Options for Aluminium Windows

When we speak about window you should take into consideration that a frame is just one element of it. Glass can also have a very large impact on safety, thermal comfort, privacy and acoustic performance.

Glass Type	Primary Purpose
Single glazing	Basic glazing requirements
Double glazing/DGU	Thermal and acoustic improvement
Toughened glass	Safety and impact resistance
Laminated glass	Safety, security and acoustic benefits
Frosted/textured glass	Privacy
Tinted/reflective glass	Solar control and glare reduction

Aluminium windows also need to be specified with appropriate glazing and hardware for their particular location and use; therefore, the most secure aluminium window will be the one that is made just for you.

Aluminium Window Sizes

Not every aluminium window will be of the same size. These limitations are real, based on profile strength and the weight of the glass, wind loads etc.

Measurements shall be taken at different points, before fabrication:

• Height: left, centre and right
• Width: top, centre and bottom

The manufacturer or fabricator should confirm the final dimensions before production.

Which Aluminium Window is Best For Each Room?

Types of Aluminium Windows in India

Sliding windows are still common to Indian homes due to space-saving and ability to have mesh. Casement windows are preferred where wider ventilation and sealing are required. Ventilators and louvred configurations work great for bathroom & utility areas.

For high-rise projects, window systems must be properly specified to meet relevant wind-load criteria.
