Marlin Windows

With our company founders' roots firmly grounded in precision aerospace engineering we apply exactly the same principles of meticulous care and attention to detail when manufacturing your aluminium windows and doors. Alitherm Heritage Doors have been designed to offer a cost-effective solution for period properties, renovation projects and contemporary buildings that require a modern high performance alternative to steel framework. Replicate the appearance of traditional steel doors from a bygone era with slim thermally efficient aluminium profiles, classic glazing bars and panels to create a vintage look.

Our showroom products are demonstrated by Marlin technical advisors who have considerable experience in the aluminium glazing industry. They fully understand system specifications and available options including any design limitations or restrictions that apply to each product range. Our showroom doors are displayed to indicate how to achieve a low or flush threshold and we are on hand to give building construction advice on how to achieve this for your project. This includes input on structural steel work, how to safeguard against cold bridging, damp protection measures and correct methods of frame fixing.
