By bringing more light into your home with an inline sliding patio door, it can make any room feel larger and more of an open area.

* in our opinion

Many customers tell us that they would like Patio Doors, and they actually have a vision of Double Doors, also known as French Doors. Whenever the term Patio Doors is used though, we get excited, because we love installing these amazing products.

PatioMaster has been manufacturing these industry leading products since 1988, so there is nothing they don't know about making the perfect patio door, and probably no design they haven't seen or produced. The potential to fill any gap certainly does exist, no matter how wide!

At Composite Doors Cardiff Limited we only ever provide PatioMaster inline sliding patio doors, as we know that they look great, feel great and just do the job!


By choosing a PatioMaster in-line sliding patio door, you are not only choosing style and security, you are also choosing warmth, more light and a greater feeling of openness and space. You are also choosing to add unsurpassed security - long gone are the days of patio doors being insecure or easy to break into. These uPVC patio doors are technically advanced, high performing doors! 


Despite the fact that these Patio Doors are absolutely solidly built, time served knowledge, experience and engineering excellence have ensured that they are sooth and easy to operate. All doors feel lightweight thanks to the easyglide technology, meaning they are smooth and effortless to open and close.

What our customers say

Kathryn, Cardiff

I found Rob to be professional and trustworthy and a fantastic communicator. He provided brilliant support from start to finish during the project he assisted me with. He also offered me a product which far exceeded my expectations. I am so happy with my 'stable' door' it fits the bill exactly! Rob kept in touch every step of the way and order to installation only took about a fortnight. Thanks Rob and your team for a VERY satisfied customer who would recommend you anytime.
