    What materials are used to make these curved windows?

    Our curved windows are crafted from high-quality aluminium, chosen for its durability, resistance to corrosion, and minimal maintenance requirements. Aluminium also allows for slim frames that retain strength over time.

    How do curved aluminium windows improve energy efficiency?

    Curved aluminium windows are fitted with advanced thermal insulation, achieving U-values as low as 1.4 W/m²K. This design helps maintain stable indoor temperatures, reducing the need for heating and cooling, and lowering energy bills.

    Are these windows suitable for conservation areas?

    Yes, our curved windows blend traditional aesthetics with modern performance, making them ideal for conservation areas. They maintain the character of heritage buildings while offering energy efficiency and safety.

    Can I customise the design of my curved windows?

    Absolutely. Each window is custom-made to fit your specific requirements, from exact dimensions to unique design features. Aluminium’s flexibility allows for bespoke shapes, including true arches and custom curves.

    What safety features are included in curved aluminium windows?

    Our curved windows feature safety glass, which is designed to hold together if broken, reducing the risk of injury. This is especially beneficial for family homes where safety is a priority.
