Aluminium Windows
Aluminium’s inherent strength allows windows and doors to be made with super-slim frames. And when there’s less frame, there’s more glass, more light and better views. Another benefit is that frames can be larger, without the need for expensive reinforcing. That’s why aluminium is perfect for today’s architecture and its wide expanses of glass. It’s simply ideal when there’s a large gap to span.
Aluminium frames are long-term performers. The material is resilient, durable and will last for decades without the fuss of constant maintenance. And if, eventually, the frames need to be replaced, the aluminium can be recycled.
All things considered there’s nothing to beat aluminium for windows and doors.
Benefits of Aluminium Windows
Aluminium windows, especially those from the Stellar range, offer a wide array of benefits that make them a smart and stylish choice for modern homes. One of the standout features is their ultra-slim profiles, which are up to 30% slimmer than those of competing systems. This design maximizes the glass-to-frame ratio, allowing more natural light to enter your home and offering clearer, more expansive views. The sleek look not only enhances the aesthetic of any space but also contributes to a brighter and more open environment.
In terms of energy efficiency, Stellar windows are built with advanced thermal break technology. This innovation helps maintain excellent insulation, enabling the windows to achieve impressive energy ratings—up to A++—and U-values as low as 0.9 W/m²K when triple glazing is used. This level of performance significantly reduces heat loss, helping to keep your home warm in the winter and cooler in the summer, ultimately lowering energy bills.
Durability is another strong point. Aluminium is inherently strong and corrosion-resistant, which means these windows won’t warp, rot, or swell over time. The Stellar system comes with long-term guarantees, including a 10-year mechanical guarantee and a 25-year powder-coated surface finish guarantee, reflecting its lasting quality and reliability.
Maintenance is minimal with aluminium windows. The powder-coated finishes are easy to clean, resistant to fading, blistering, and peeling, and require little more than an occasional wipe-down. This makes them ideal for homeowners looking for a low-maintenance yet high-performance option.
Sustainability is also a key factor. Stellar windows use around 30% less aluminium than comparable systems and are fully recyclable. Their responsible manufacturing processes and reduced material use make them a greener choice for environmentally conscious homeowners.
Security has not been overlooked either. Stellar windows feature multipoint locking systems, internally glazed frames, and high-security Yale locks. The entire system meets PAS 24 and is compatible with the Secured by Design initiative, offering excellent protection against intruders.
Style and customisation are central to the Stellar offering. Homeowners can choose from flush casement, fully flush, tilt & turn, fixed, and even sliding or bifold door styles. These windows are suitable for both contemporary and traditional architecture, and there is a wide choice of colours, finishes, and hardware to match any design scheme.
In addition to these benefits, aluminium windows help create a more comfortable and peaceful indoor environment. They can incorporate sound-reducing glass and offer strong insulation to keep outside noise at bay. Moreover, every window and door in the Stellar range can be tailored to individual layouts and lifestyle needs, offering both design flexibility and functional performance.
Finally, one unique feature exclusive to Stellar is the reverse butt joint. This patented design element allows for internal glazing without compromising the clean exterior look by avoiding unsightly external beads or dummy sashes. This clever detail maintains the system’s sleek aesthetic while improving ease of installation and material efficiency.
Overall, Stellar aluminium windows combine elegance, energy efficiency, durability, security, and design flexibility, making them a top-tier choice for homeowners who want the best in both performance and appearance.
