3G Patio Doors

[Onoff]

I'm in the market for a set of 3G patio doors. Yes the place is heat leaky like a sieve but I have to start somewhere. This as part of a lounge / diner knock through.

 

Very rough dimns of the patio doors are 2030h x 2070w. The height will need to increase as the lounge floor is at the moment much too high compared to the dining room (floor), in fact there's a ramp. (It's a lot more than a simple knock through tbh). 

 

 

 

Ideally I'd like to up the window width to circa 2400mm but I'm not sure how wide the lintel is above. 

 

Should I look at "off the peg" or go bespoke once I have a size?

 

I've heard 3G patio doors are rather heavy on the rollers?

I have 3G sliding patio doors and a set of bifolds made by a local company. They are Aluminium and work very well, nice clean to move. Not fingertip light but very easy. I went to look at the showroom where they had double glazed samples but were confident they would work properly.
