Aluminium office windows
Modern offices are defined by light and energy efficiency — The Heritage Window Company aluminium windows deliver both.
Our slim-profile commercial window frames flood workspaces with natural light, while superior glazing and thermal break technology help windows meet energy targets and reduce running costs.
Available in bespoke sizes, custom RAL colours and double-glazing configurations, our slimline aluminium windows are a natural fit for offices of all sizes.
Stronger than uPVC and suited to larger apertures, our aluminium office windows use advanced multi-point locking systems for enhanced security and peace of mind. For office refurbishments in or near conservation areas, our heritage architectural experience ensures the right specification from the outset.
