Composite Front Doors
Our composite front doors combine advanced security features with thermal efficiency. Engineered with 360 aluminium reinforcement and high-density PU foam, they offer 35% greater strength than standard GRP doors while maintaining A-rated energy performance. The patented S-Glaze technology permanently locks glass into the door structure, eliminating vulnerable glazing cassettes. Available in 13 colours and 30 styles, these doors provide lasting protection and style for UK homes.
Composite Back Doors
Specialised composite back doors address unique security challenges with reinforced aluminium frames and multi-point hook locks. Designed to withstand forced entry attempts, these doors incorporate the same S-Glaze technology as front doors while offering discreet aesthetics. Their thermal efficiency reduces energy bills, and customisation options ensure seamless integration with property design. Emergency services can access properties using specialist equipment without compromising daily security.
Door Customisation
Our 3D door designer enables complete customisation with 13 colours, 30 styles, and 100+ glass designs. Customers visualise their chosen configuration on their home before manufacturing.

Please DO NOT waste your money with a rock door. Its expensive yet bad quality. They look good and thats all. They say it has a energy rating of A or A+ HAHA yeh right absolutely nonsense more like A and A + to let cold air in your home. Dont bother with email or phone calls because you wont get a response.

Our first door developed some small bubbles a few years after installation and to be honest we were tardy in doing anything about it. It wasnt until the supplier visited our property for another reason and said this is faulty , you should get it replaced under warranty, that we took action. Less than two years later the replacement door (pictured) looks like this. Rockdoor wont replace it because the warranty starts from the installation of the original door. So Door 1 became faulty probably after about four years, door 2 after less than two years. Not a spectacular track record. The

DO NOT BUY A ROCKDOOR... Your old door will be less trouble!! I always read reviews, but very rarely leave them. But I feel I need to leave a review on Rockdoor. If you take notice of any reviews, please read all of these about Rockdoor and do not buy at Rockdoor at any costs.
Firstly, yes these doors are solid and they look great, but the quality is so poor. Based on my experience, I believe there is an inherent fault with these doors which is down to the sun. We have 2 Rockdoors which were both installed November 2018. We always use the side door and rarely use the front door at all

The design is lovely and door itself looked great when it was fitted. We went with a local Rockdoor approved installer and to be honest I cannot and will not fault them at all. We had a Rockdoor Ultimate Newark, installed in 2017. Within 12 months we had some bubbles appear in the door, this was replaced, door 2 had the same issues, door 3 arrived bent and was rejected prior to installation, door 4 developed the same "bubbling issue". We are now on door number 5 installed in Feb 2020 which again has the same issue and are waiting on door 6 replacement (delayed due to COVID). For anyone interested

My back door is well over 10 years old and has stood the test of time recently had my front door fitted and again the quality and security stands out a mile. You need a quality fitter for a quality door.
