Aluminium windows are the premium choice for homeowners seeking slim-profile, high-performance windows with a contemporary aesthetic. Thermally broken and available in any RAL colour — including striking dual-colour combinations — our aluminium windows maximise the glazed area of your openings while delivering outstanding thermal efficiency, security and longevity. Ideal for modern new-builds, renovations and coastal properties across St Austell and all of Cornwall where salt-air resistance and long-term durability are essential. Every aluminium window we supply is Certass registered and backed by our 10-year insurance-backed guarantee.
All our aluminium windows feature thermally broken frames — meaning a non-conductive polyamide strip separates the inner and outer aluminium sections to prevent heat transfer and eliminate cold bridging. This delivers A-rated thermal performance without sacrificing the slim sightlines aluminium is known for.
Our aluminium windows are available in any RAL colour — giving you complete design freedom. Choose from classic anthracite grey, jet black or pure white, or specify a dual-colour frame with a dark exterior and light interior finish to suit both the kerb appeal and interior decor of your St Austell home.
Aluminium's inherent strength allows for much slimmer frame profiles than uPVC — maximising the glazed area of every opening and flooding your rooms with natural light. This makes aluminium windows particularly popular for large picture windows, corner glazing and feature openings across modern homes in St Austell and nearby.
Aluminium is naturally resistant to corrosion and requires no painting or sealing — making it an ideal choice for coastal properties across Fowey, Padstow, St Mawes and Falmouth where salt-air exposure can deteriorate other materials over time. With minimal maintenance, aluminium windows will look and perform like new for decades.
Aluminium windows offer slimmer frames, a more premium aesthetic and superior corrosion resistance — making them ideal for contemporary homes and coastal properties. uPVC windows are more cost-effective and offer excellent thermal performance. The right choice depends on your budget, property style and requirements. Our team will advise you.
