Just installed the very same, overall length of 320cm, with one half sliding over the other. PVC and triple glazed, height of 230cm. Great piece of engineering, as it slides open effortlessly.
Bought from an Austrian company via its Dublin based branch,
www.hrachowina.ie - it is called a lifting / sliding door.
The thing is heavy, which makes for some work for the installers, but it doesn't matter once installed.
Quality is excellent but you are looking at around 7-8K plus installation.
We got all other Windows and front door as well (renovation / extension) so price might depend on overall package.
No connection to the company beyond being a happy customer and having grown up Austria, so know the brand for decades.
