Aluminium Sliding Patio Door Overview & Specifications

Capital Windows Sliding patio door is now established as a market leader and one of the most tried, tested and reliable  aluminium sliding patio doors on the market. It is a sliding door that will give you expansive glass views coupled with contemporary design and exceptional quality.

We manufacture our impeccable aluminium sliding patio doors under stringent manufacturing procedures to provide you with a high quality product that will give years of sterling service. Patio doors are particularly useful for flats and apartments or for small patio areas where you may not want any kind of outward opening door to take up any of your outside space. The slim design of patio doors means you enjoy more glass area, more visible light and less visible aluminium.

Also as all the panels slide within their tracks, all panels are inline ensuring they do not encroach into your room. Available with either single, double or triple track profiles, this means your sliding panels can open and slide exactly how you want them. This ultra reliable and smooth running sliding door system is particularly useful where space is at a premium such as apartments and flats including typical domestic applications.
