FAQs

What are the main advantages of choosing aluminium windows for a home in Johannesburg? 

Aluminium windows are highly durable, lightweight, resistant to rust and warping from weather fluctuations, and require very little maintenance. They also offer a modern, elegant aesthetic and can be customised for various architectural styles.

Are aluminium window frames energy efficient? 

Modern aluminium frames, especially those incorporating a “thermal break” technology, are very energy efficient. When paired with double glazing, they significantly reduce heat transfer, keeping your home cooler in summer and warmer in winter, thus lowering your energy bills.

What is double glazing and how does it benefit my property in Johannesburg? 

Double glazing consists of two panes of glass separated by a sealed space filled with air or an inert gas. This acts as an extra layer of insulation, improving energy efficiency, reducing noise pollution, and minimising condensation.

How does double glazing in aluminium windows save money on utility bills? 

By providing superior insulation, double-glazed windows limit the amount of heat that escapes in winter and heat that enters in summer. This means your heating and air conditioning systems don’t have to work as hard, leading to significant savings on electricity consumption.

What is a thermal break and is it important for aluminium windows? 

A thermal break is a non-conductive material (like a special plastic resin) placed between the inner and outer sections of the aluminium frame. It is essential as it prevents heat or cold from transferring directly through the highly conductive aluminium, drastically improving the frame’s thermal performance.

What is the typical lifespan of a quality aluminium window in a climate like Johannesburg’s? 

High-quality aluminium window frames are exceptionally durable and resistant to corrosion. With minimal maintenance, they can last for many decades, often exceeding a lifetime guarantee from reputable manufacturers.

What different styles of aluminium windows are available? 

Common styles include casement windows (which open outwards like a door), sliding windows (which slide horizontally), tilt-and-turn windows (which open in two ways), and fixed-pane windows (which do not open). The best choice depends on your space and ventilation needs.

How much does a standard aluminium window cost in Johannesburg? 

The price varies significantly based on size, style, and glazing. A standard aluminium window (e.g., 900×900mm) without installation can typically range from R1,300 to R2,500, with installation adding R1,500 to R2,500 or more per unit.

How much more expensive is a double-glazed aluminium window compared to a single-glazed one? 

Double-glazed options generally cost between 35% and 50% more than their single-glazed counterparts. However, this higher initial investment is often offset by the long-term energy savings.

What factors primarily influence the final price of aluminium window installation in Johannesburg? 

Key factors include the window style (casement, sliding, etc.), size and degree of customisation, type of glazing (single, double, or low-emissivity), quality of the aluminium profile (with or without a thermal break), and the complexity of the installation process.

Can I use the bulkhead to hide the curtain rails for my large aluminium stacking doors?

Yes, this is a very popular design choice. An L-shaped or U-shaped bulkhead is often installed a short distance from the window/door reveal to create a recess (or “pelmet”) perfectly sized to conceal the curtain tracks, creating a very neat and high-end finish.

Can I install the new aluminium windows myself? 

While simple products like some casement windows and sliding doors can be installed by an experienced builder, it is generally recommended to use a professional installer. They ensure correct fitting, sealing, and compliance with building regulations for optimal performance and security.

How long does an aluminium window installation typically take for a residential property? 

The duration of the project depends on the number and type of windows being installed. A site assessment is required for an accurate estimate, but a typical full-house replacement for a standard three-bedroom house usually takes several days.

Are aluminium windows a good choice for security in Johannesburg? 

Yes. Modern, high-quality aluminium windows and doors are very secure. Look for products that feature multi-point locking systems, robust hardware, and security glazing options to ensure they meet the highest safety standards.

What types of glass can I choose for my aluminium windows? 

Beyond standard glass, you can choose from energy-saving Low-E (low-emissivity) glass, toughened or laminated safety glass for security, or acoustic glass for enhanced sound reduction, which is beneficial in busy urban areas.

Do I need special cleaning or maintenance for aluminium window frames? 

No, aluminium is very low-maintenance. The frames can typically be cleaned simply by wiping them down with a soft cloth and a mild soap-and-water solution every few months to remove dust and debris.

Can I get custom-sized aluminium windows for unique openings in my home? 

Yes, aluminium is an extremely versatile material, and manufacturers in Johannesburg regularly supply custom-made windows and doors to fit non-standard or oversized openings and bespoke designs.

What colour options are available for aluminium window frames? 

The frames can be finished in a wide variety of powder-coated colours, with popular options including white, charcoal grey, and black. A natural anodised (silver) finish is also available and is often a cost-effective choice.

Do aluminium windows require weatherproofing? 

High-quality, modern aluminium window systems are designed to be weather-resistant and feature integrated seals and weather stripping to prevent water and air leakage, even in adverse weather conditions.

Which must be done first: Glazing (installing the glass) or applying RhinoLite?

The glazing (windows and frames) must be installed and properly sealed first. RhinoLite (or any interior plaster) should only be applied once the building is “closed in,” meaning the roof, windows, and external doors are complete and watertight. This prevents moisture damage to the fresh gypsum plaster.

Should I choose casement or sliding aluminium windows? 

Casement windows generally offer superior ventilation and better seals for energy efficiency. Sliding windows are excellent space-savers as they do not project outwards and are a popular choice for large openings or restricted spaces.

Do suppliers offer a guarantee or warranty on their aluminium windows and installation? 

Reputable manufacturers and installers in Johannesburg typically offer a guarantee on both the product quality (the frames and components) and the installation workmanship, providing you with long-term peace of mind.
