The British winter is an unpredictable beast. There can be rain, there can be snow, there can be cold. But it can also be mild, dry, sunny and even relatively warm, and it is this uncertainty which drives homeowners wanting to replace their windows to look for an all-seasons solution.
This comes in the form of aluminium casement windows. In recent years they’ve become an extremely popular choice for both modern and traditional homes due to their versatility, durability and thermal efficiency. Unlike older window materials, modern aluminium frames provide superior insulation, helping to keep the cold out and the warmth in during chilly winter months, while helping to keep rooms cool in warmer summer weather.
Thermal break technology
One of the key advantages of aluminium casement windows is their thermal break technology. This creates a barrier between the interior and exterior surfaces of the window frame, significantly reducing heat transfer. The thermal break is typically made of a low-conductivity material such as polyamide, which effectively separates the inner and outer aluminium profiles. This separation minimizes thermal bridging, resulting in improved energy efficiency and reduced condensation risk.
The thermal performance of aluminium casement windows is often measured by their U-value, which indicates the rate of heat transfer through the window. Lower U-values signify better insulation properties. Our casement windows can achieve U-values as low as 1.4 W/m²K when double glazed.
Additionally, the glazing units in these windows often incorporate low-emissivity (low-E) coatings and argon gas fills between panes. Low-E coatings reflect heat back into the room, while argon gas, being denser than air, provides better insulation between glass panes. These features create a highly efficient barrier against heat loss.
Bespoke aluminium casement windows
Aston Architectural Aluminium offers a range of bespoke casement window options that cater to various architectural styles and requirements. Our Heritage 47 system, for instance, is suitable for a variety of uses including residential, retail/commercial, conservation areas and listed buildings. This product combines traditional aesthetics with modern performance, making it an ideal choice for installers.
In addition to their thermal properties, aluminium casement windows offer excellent ventilation options for UK homeowners. The casement design allows for easy opening and closing, providing efficient air circulation when needed. Aston’s flush casement windows are particularly popular, offering a sleek appearance without compromising on functionality. The manufacturing process of these windows ensures high-quality products that meet rigorous UK energy efficiency standards.
In addition to their thermal benefits, aluminium casement windows offer several other advantages for homeowners:
- Durability: Aluminium is highly resistant to corrosion, warping and fading, ensuring long-lasting performance and appearance.
- Low maintenance: Unlike wooden frames, aluminium windows require minimal upkeep, saving homeowners time and money in the long run.
- Security: Modern aluminium casement windows come with advanced locking systems, providing enhanced security for properties.
- Customisation: Aluminium can be powder-coated in a wide range of colours, allowing homeowners to match their windows to their property’s aesthetic.
- Sustainability: Aluminium is 100% recyclable, making it an environmentally friendly choice for eco-conscious homeowners.
