Senior Architectural Systems has joined forces with composite door supplier Hallmark Doors and Panels to create a new residential entrance door that combines patented Pure thermal efficiency with PAS 24 security.

The two British based manufacturers have developed the robust external door option by combining Senior’s low U-value Pure commercial door frame with Hallmark’s aluminium doors panels.

The new front door option is available in a choice of designs from Hallmark’s range of over 50 aluminium door panels which includes both classic and contemporary styles. This design flexibility is supported by Senior’s patented Pure technology, with the door frame benefitting from an impressive thermal barrier created using ultra-efficient polyurethane foam.

The Hallmark door panels also feature an effective Raventherm thermal core for extra efficiency, with optional glazing trims.

Hallmark uses a four-stage pre-treatment process and cuts the door panels to size before powder coating to ensure a watertight seal to the edge of the aluminium skins.

Senior’s sales director, James Keeling-Heane, said: “By being able to offer an efficient and attractive aluminium front door system we are continuing the evolution of our Pure range and making stylish, secure and sustainable aluminium fenestration accessible to a wider market.”

The bespoke aluminium door panels can be ordered directly from Hallmark and then fitted into Senior’s Pure commercial doors. Customers are advised to clearly state their requirements at the specification stage as this is not a standard product. Senior’s in-house team is also on hand offer technical support and guidance on the new front door option.

Fabricators and installers are welcome to contact their local technical sales manager and specifiers, including architects, contractors, and developers, can speak with the regionally-based architectural advisory team for more information.
