Product Overview
If your property has original steel doors, or uPVC replacements that don’t suit the building’s character, the Alitherm Heritage door offers a more appropriate solution. The 59mm sightlines match traditional steel proportions, and the aluminium frames won’t rust or require regular repainting.
Both single and double door configurations are available, with PAS 24 security certification. Hardware options include heritage-style handles to complement Victorian and Art Deco properties.
This product is part of the Smart Alitherm Heritage range, along with the Heritage Aluminium Windows.
Design and Configuration Options
Available as single or double doors, in both inward and outward opening configurations. Maximum leaf size is 900mm wide by 2100mm tall.
Frames can be finished in any standard RAL colour, with dual-colour options available. Metallic, textured (Sensations), and anodised-effect (Alchemy) finishes are also offered.
Hardware options include traditional Monkey Tail and Bulb-End handles, as well as Art Deco lever handles – all available in finishes to match the frames. Marine-grade 316 stainless steel hardware is available for coastal or exposed locations.
Glazing can be tape or gasket sealed, with units from 24mm to 32mm.
