The physics of heat loss through glazing has long challenged architects and homeowners alike. Yet in our sliding door systems, we’re witnessing a genuine breakthrough in thermal technology. These aren’t just glass doors – they’re sophisticated thermal barriers that happen to offer panoramic views and seamless access to your outdoor space. At Aston Architectural Aluminium, we’ve engineered these systems to tackle Britain’s complex climate head-on while delivering the clean lines that modern homes demand.
Superior thermal efficiency
Modern aluminium sliding doors are engineered with advanced thermal break technology, creating a barrier between the interior and exterior frames. Our AS-20 and AS-25 systems feature multi-chambered profiles and high-performance weather seals, significantly reducing heat transfer and helping to lower energy bills.
The AS-25 system achieves impressive U-values as low as 1.3 W/m²K when specified with triple glazing, whilst the AS-20 offers excellent thermal performance with double glazing options. This thermal efficiency means your home stays warmer in winter and cooler in summer, providing year-round comfort.
Maximising natural light
Both our AS-20 and AS-25 sliding patio doors feature slim frames and minimal sightlines, allowing large expanses of glass to flood your living space with natural light. The AS-20 system boasts incredibly slim 20mm interlock stiles, whilst the AS-25 maintains sleek aesthetics with marginally deeper profiles for larger openings.
This abundance of natural light not only creates a beautiful indoor environment but can also reduce reliance on artificial lighting, contributing to lower energy consumption.
Durability and low maintenance
Aluminium frames offer superior strength compared to uPVC alternatives, allowing for larger glass panels without compromising structural integrity. Our sliding door systems are powder-coated to provide exceptional resistance to corrosion, requiring minimal maintenance to maintain their appearance. The lightweight nature of aluminium, combined with precision-engineered running gear, ensures smooth operation for years to come. This durability makes aluminium sliding doors a great investment for homeowners seeking long-term efficiency.
Customisation options
Our sliding patio doors are available in a range of sizes and configurations to suit different property styles. Popular finishes include anthracite grey aluminium, which complements both traditional properties and contemporary homes. We also offer various glass options, including safety glass and integral blinds, allowing you to tailor the doors to your specific requirements.
Meeting building regulations
All our aluminium sliding doors are manufactured to meet or exceed current UK building regulations. The AS-20 and AS-25 systems are tested to the highest standards for weather resistance, security, and thermal performance, providing peace of mind for homeowners.
The perfect solution for modern living
Whether you’re creating an open-plan kitchen that flows into your outdoor space or simply wanting to improve your home’s energy efficiency, our aluminium sliding doors offer the perfect solution. The combination of slim frames, large glass panels, and exceptional thermal performance makes them an ideal choice for homeowners looking to create a more efficient and visually striking property.
