Strong, durable, and sleek aluminium entrance doors in Norfolk & Suffolk

Hallmark’s Aluminium Doors utilise Smart Alitherm door profile designed to provide superior performance solutions for today’s specification demands. Our Aluminium doors perform well against the rigours of the Great British weather, reducing draughts and providing excellent weatherproofing. This enables the doors to maintain their high performance even in the most extreme locations.

Security concerns are alleviated by the use of the superbly engineered and ‘Secured by Design’ approved Winkhaus Key-Wind Lock – a multi-point locking mechanism allowing our doors to exceed the requirements of PAS 24 (Enhanced Security). To complete the collection, the Alitherm Door range is available with various threshold and cill options including low-rise for compliance with the Disability Discrimination Act (DDA).
