Aluminium Heritage Window – 1 Transom (Style 4)

Our Heritage Aluminium windows have been carefully priced to accommodate various budgets and crafted to appeal to a wide range of preferences. They replicate the appearance and slim sight lines of traditional Steel windows and come as close as you can get to a steel window, using a thermally broken aluminium profile. These steel look-a-like windows not only provide an authentic appearance, but they also offer much improved security, and thermal efficiency, and come at a fraction of the cost of steel. The inherent strength of aluminium enables the design of our windows while maintaining their durability, aesthetic appeal, and practicality. Aluminium is lightweight, easy to handle, and requires minimal maintenance. Our windows feature multiple robust rubber seals to ensure that the only thing passing through your window is sunlight. Our heritage window system incorporates cutting-edge polyamide thermal barrier technology, creating a barrier that prevents heat loss, minimizes condensation, and insulates your property from external noise and weather conditions.

We proudly manufacture and assemble all our products in the UK, ensuring quality, compliance, and security. Our in-house manufacturing, state-of-the-art machinery, and highly skilled staff guarantee that every window leaving our factories meets the highest standards of perfection. Our streamlined operations allow us to deliver quality products to you with both competitive pricing and efficiency.

We recognize that security is a paramount concern when upgrading any window system, which is why we source our hardware from internationally recognized and trusted brands.
