Heritage French Doors In Slough & Berkshire

Heritage French doors are produced using thermally broken polyamide. Our heritage French doors are ideal for period properties but are more than capable of adding character to a new build with their stunning industrial-style look. These doors are the perfect replacement for traditional steel doors as they replicate the design of said doors with the added advantage of contemporary manufacturing through advanced technology. Heritage French doors are especially ideal for heritage building conservation areas where building regulations require a like-for-like replacement to steel doors. New Look Double Glazing’s heritage French doors possess and ultra-thin lightweight and high-strength frame alongside the aesthetics of a traditional steel door. However, these doors trump traditional steel doors with their exceptional lifespan, improved thermal efficiency, and reduced maintenance as well as their cost-effectiveness.

Why choose Heritage doors?

Heritage French doors are influenced by a magnificent style, made famous in the 19th century. This style allows you to divide your door into sections using aluminium frames without disturbing the outdoor view. Here at New Look Double Glazing, we incorporate the traditional design of heritage with modern aluminium window technology to manufacture these magnificent doors. The slim aluminium frames on these doors means that you won’t be compromising on light or space.  

Increased lifespan

Because aluminium does not rust or rot, door frames provide great longevity and can last indefinitely. This also means that the aluminium windows have the longest lifespan of any door framing material, with typical replacement periods of 40 years.

Excellent thermal performance

Modern heritage doors are thermally broken using state-of-the-art polyamide, an excellent insulator that helps to insulate doors against heat loss. The thermal conductivity of polyamide is 160 times better than steel, which for a typical terraced house would provide a saving of around £95 each year in fuel costs. In addition to these energy savings, the polyamide also raises the internal temperature of a house, helping to reduce the risk of condensation. This technology significantly reduces thermal transmittance and enhances the overall u-value of a product. Therefore, our heritage doors have exceptionally low u-values of 1.5 W/m2 k when installed with a suitable sealed unit.

Low maintenance

Maintenance for heritage French doors is simple and straightforward, with a routine ‘wipe-clean all that is required to keep them looking their best. With no requirement for re-painting or re-varnishing, heritage doors will never fade, deteriorate, or rust, even in harsh environments, such as coastal locations, where steel doors can be particularly prone to rust, requiring regular maintenance and eventually, replacement.


We understand that you would have second thoughts about installing a door with complete visibility into your property. New Look Double Glazing places a high value on the security of your property, which is why we have installed advanced multi-point locks onto our Heritage French doors to ease your worries.
