Single panel curtain for patio door

[Thatsbetter]

Sorry, bit of a boring question....

Our living room is open plan through to a draughty patio door so I want some a thermal curtain. For style and practical reasons I'd prefer a single panel curtain but the pole would be approx 2m wide and drop 2.6m.

Is it possible to purchase and fit something like this or amino unrealistic? I'm thinking maybe fabric doesn't come in widths big enough but two bits could be joined together? Also would a pole that width be ok with just two brackets as if it needs three then it wouldn't be possible to fit a single panel.

We have one similar size(ish). It's on a metal pole (around 2.5m long I think) with two brackets and the curtain itself is a very heavy thick velvet, weighs a ton!
The curtain is made from 5 vertical panels joined together.
So definitely feasible!

Thanks TheGreenNinja it's good to know that it's feasible. Did you get yours made locally?

It was here when we bought the house so no idea I'm afraid!
