Aluminium is well-known for its incredible durability and strength, boasting a lifespan of 30 to 40 years. This makes it a solid, long-term investment for your home. Unlike uPVC, which can warp or fade over time, aluminium keeps its shape and color even when faced with tough weather conditions.
Our fixed aluminium windows come equipped with cutting-edge InsuLock multi-chamber thermal break technology, achieving impressively low U-values—down to 1.5 W/m²K for double glazing and 1.0 W/m²K for triple glazing. This not only meets but exceeds building regulations, helping you save on heating costs.
Absolutely! The sturdy nature of aluminium combined with the non-opening design of these windows means there are no vulnerable points like hinges or locks. This makes them highly resistant to forced entry, making them perfect for high-security areas such as ground-floor installations or commercial spaces.
Absolutely! You can choose from a range of frame profiles (like flush or stepped), a selection of nine powder-coated colors plus three premium anodised finishes, and various glazing configurations (double or triple). This makes it easy to find the perfect match for your style and enhance your home’s aesthetic.
Aluminium needs minimal upkeep. It’s resistant to corrosion, UV degradation, warping, and fading and holds its finish well over time. A simple routine—wiping with warm soapy water every few months—is all it takes to keep frames and handles in top condition.
