Discover why our aluminium doors are so special

Exceeding expectations & regulations...

All RK aluminium front doors far exceed the current recommended energy efficiency regulations. Doors energy efficiency is measured as a 'U value' and new doors must have a minimum U value of 1.8W/m2K (1.6W/m2K in Scotland) or less, with lower numbers being better. A typical wooden door might have a U value of around 2.5W/m2K and a lot of new doors will be just meeting the basic requirement of 1.80W/m2K...

Our aluminium doors far exceed this level and our 'Excellence' Premium door has a U value rating at an amazing 0.67W/m2K* with our 'Excellence' Standard door has a U Value of 0.92W/m2K*, far better than many other doors on the market.

Enhanced security on all RK aluminium doors...

All our aluminium doors are very secure and benefit from "Secured by Design" and "PAS 24:2022" enhanced door security certification to ensure full compliance with UK Buidling Regulation and insurance requirements and giving our customers complete peace of mind.

You can even add our finger print entry system for added door security and convenience.

RK Door Systems can also fit ULTION CYLINDERS  if required, described as the most secure lock ever made, the Ultion cylinder has never been beaten in any test and achieved all leading security accreditations. We understand security is important thats why we offer these highly secure locks as an option.
