Heritage Aluminium Casement Windows

Alitherm Heritage stands out as an ideal modern substitute for traditional building materials, especially in scenarios where planning or design guidelines require materials that blend seamlessly with the existing environment. This is even applicable to listed buildings. Various Local Authorities, including those in the London Boroughs of Islington, Camden, and Tower Hamlets, Watford Borough Council, and Essex County Council, as well as Cadw, the Welsh Government’s historical environment service, have approved the use of this system.
Both the door and window ranges in the Alitherm Heritage line showcase the slim profiles and fine sight lines characteristic of traditional steel doors and windows. However, they also incorporate the excellent thermal efficiency of a contemporary aluminium system, each achieving a ‘B’ Energy Rating.
They are designed to accommodate various sizes and come equipped with multi-point locking mechanisms and face-mounted finger thrown locking bolts. Both window and door systems offer a U-Value of 1.5 W/m²K when installed with an appropriate sealed unit. They are available in single or dual polyester powder-coated finishes.
The Alitherm Heritage balcony doors, suitable for both single and double door setups, are offered in a diverse range of configurations.
