Called the world’s leading standard in energy efficient design, the German-conceived Passivhaus standard is increasingly specified by Architects and Developers in the UK. The PH standard is a building and construction concept, designed to dramatically increase the energy efficiency, comfort and longevity of a newly built property, compared to existing UK housing stock.
KAT aluminium K64 front doors easily qualify for Passive House designed homes as the solid designs are only 0.77W/(m²K). These fabulous KAT K64 Series doors are game changers for UK customers because they are priced at the same level as an equivalent composite door.
In today’s residential new build and home improvement markets, KAT is aware that customers are looking for doors that are a ‘step up’ from the ubiquitous composite or entry level timber door; a door that offers ‘fit and forget’ installation, security, style and energy efficiency. The K64 collection delivers all that and more. These very high-quality aluminium doors combine sleek aesthetics and outstanding performance, perfect for those that seek the best price to performance ratios.

Luxurious, Affordable Entrance Doors
These doors combine the strength and stability of a steel/timber hybrid door leaf with the reliability of an aluminium frame, all wrapped in Renolit Exofol. This high-performance Renolit surface treatment features Solar Shield Technology, which reflects infrared radiation to prevent heat build-up and preserve the stability of your door. KAT offers 18 exterior finishes, including dual colour options, helping you find the perfect match for your project.

Energy efficiency is crucial in combating climate change and reducing emissions. With an incredibly low U-Value of just 0.77 W/m²K for solid designs and 0.88 W/m²K for glazed options, the K64 collection of doors can handle the toughest weather conditions whilst meeting Passive House standards. Renolit foil is market proven across the world and performs reliably in all conditions, including Marine environments. Get in touch with KAT

Highly Secure, Low Maintenance, Long Lifespan
We are aware that homeowners require front doors that offer both premium quality and robust security and we are confident that K64 meets the demand.
All K64 models meet RC2 and PAS 24 security standards, providing our installation teams with a very high-quality front door, which meets regulatory requirements on new builds and renovations.
Affordable Aluminium Entrance Doors
For years, composite doors have been the go-to for budget conscious homeowners. But now, KAT offers you an aluminium option, for the same money as most mid-range contemporary composite doors. Plus, KAT can manufacture much wider and higher doors because of the strength of the door sash.

Go large with Easy Installation and Customisation
KAT’s K64 front doors are engineered with precision in a highly automated factory, meaning faster, hassle free installations. As standard, K64 doors come with a round pullbar externally and a lever handle internally, in either a contemporary textured Black or brushed Steel finish. Customisation options include larger sizes up to 1.1m mm wide and 2.2m high, plus side panels, top lights, and additional hardware, including a thumbturn, spyhole, and letterbox. This flexibility allows you to design each door to suit the needs of the individual project.
Sustainability and Environmental Benefits
Aluminium is one of the most sustainable materials being 100% recyclable without loss of quality. Whilst the doors will look good and continue to perform as designed for many years, the energy saving benefits at the end of their life supports broader sustainability goals, reducing carbon emissions and enhancing energy ratings for homes.
Capability
We produce 3000 of these front doors a month and they are sold all over Europe. Dubbed by many as ‘the future of affordable luxury front doors’, KAT can also arrange installation anywhere in the UK.
