What makes Smart’s Alitherm Heritage doors suitable for heritage and conservation projects?
These doors are specifically designed to meet the stringent requirements of heritage and renovation projects. Their slim sightlines and elegant profiles closely replicate the appearance of traditional steel doors, ensuring that the door maintains the architectural integrity of historic buildings.
The door profiles feature the Heritage system’s signature slim frames and clean lines that complement Smart’s Heritage windows, offering a complete solution for large scale replica-refurbishment projects. Additionally, the door has been approved for use in various conservation areas and by local authorities, making it an ideal choice for projects where preserving historical aesthetics is crucial.
How does the Alitherm Heritage door contribute to energy efficiency?
The Heritage door is designed with advanced polyamide thermal break technology, which significantly enhances its energy efficiency. This allows the door to achieve a U-value of 1.5 W/m²K when combined with a suitable sealed unit. This feature ensures that the door can meet modern building standards while still maintaining an authentic look.
What are the advantages of aluminium doors over traditional steel doors?
Aluminium doors offer several advantages over traditional steel doors. Aluminium frames are able to provide superior thermal efficiency due to polyamide thermal breaks that reduce heat transfer. They are also more durable, as aluminium is resistant to rust and corrosion, requiring less maintenance than steel. Additionally, aluminium doors provide greater aesthetic flexibility, with various colour and finishing options, and their lightweight yet strong nature allows for larger glass areas with slimmer frames.
