Alithem Heritage Residential Doors

Elevate your heritage project with the Alitherm Heritage Residential Doors from CBP, combining classic design with modern thermal efficiency. 

Product Overview 

Alitherm Heritage offers a modern thermal aluminium solution perfect for both heritage and refurbishment projects, especially where the replacement of old steel windows is essential. Designed for applications such as listed building renovations and large-scale replica-refurbishment projects, these doors respect planning constraints while providing outstanding performance. The Alitherm Heritage profiles utilize Smart’s innovative polyamide thermal break technology, significantly reducing thermal transmittance and enhancing overall U-values, ensuring compliance with Document L 2010. 

These doors are available in a range of standard and non-standard colours, including metallic, dual colour, Smart’s Sensations textured, and Alchemy anodised effect finishes, offering extensive customisation options to match any design vision. 

Product Features

The Alitherm Heritage doors are designed to emulate the slim sightlines and elegant contours of traditional steel doors while delivering modern performance and security. Available in single or double door configurations, they feature multi-point locking and face-mounted shoot bolts for enhanced security. The polyamide thermal break provides superior thermal performance, ensuring that your home stays comfortable in all weather conditions. 

With a choice of single or dual colour finishes and marine-quality polyester powder coating as standard, these doors are both durable and visually appealing. The inclusion of 316 marine-grade stainless steel hardware and heritage or Art Deco hardware options allows for a high degree of personalisation, ensuring that your doors fit perfectly with your design aesthetic. 

Design and Engineering 

Alitherm Heritage doors are engineered to meet the highest standards of design and performance. The slim sightlines, at just 59mm, provide an elegant and unobtrusive appearance, making them ideal for heritage and conservation areas. The innovative polyamide thermal break technology creates a barrier between the cold air outside and the warm air inside, enhancing the overall U-value to 1.6 W/m²K when using a 1.0 W/m²K glass unit. 

The doors are designed for flexibility and can accommodate glazing units between 24mm and 36mm, whether double or triple glazed. With maximum sash widths of 900mm and heights of 2100mm, Alitherm Heritage doors can be tailored to fit a wide range of openings, ensuring a perfect fit for any project. 

Security and Energy Efficiency 

Security is a paramount feature of the Alitherm Heritage doors. They are rigorously tested to PAS 24:2016 standards, ensuring that they provide robust protection for your home. The doors also comply with BS 6375 for weather testing and performance characteristics, ensuring they stand up to the elements and provide long-lasting performance. 

Energy efficiency is another key strength of the Alitherm Heritage range. With a B Energy Rating and an impressive U-value of 1.6 W/m²K, these doors help to reduce energy costs and maintain a comfortable indoor environment. The thermal break technology significantly reduces thermal transmittance, making these doors a smart choice for both heritage projects and modern homes alike.
