ᐅ A 2-meter-wide patio door without a central mullion is recommended. Is there a warranty?

Hello everyone,
We are building a detached house with our general contractor. In the living room, a 2m (6.6 ft) wide terrace window / patio door (triple glazing) will be installed (profiles by Salamander). Our window installer wants to put a vertical post in the middle – he believes it won’t function properly otherwise.
A 2m (6.6 ft) wide roller shutter tends to bend and could be blown out during a storm (with a post, the roller shutter would be divided – that means two shutters, each 1m (3.3 ft) wide). We would prefer a design with a mullion instead of a post (we currently have this in our rental apartment, but without a roller shutter).
The installer does not refuse the installation completely but says that if we insist on not having a central post, he will disclaim responsibility for any defects related to the hardware, the frame, and the roller shutter.
Now I have the following questions for you:
1) What do you think about this? Is our window installer right, or is he just being overly cautious? We obviously do not want the fairly wide roller shutter to bend.
2) Do you have any experience with such a wide window? What should we ask the installer for during installation (reinforced profiles, etc.)?
3) Can the installer legally exclude warranty simply like that?
Best regards and many thanks,
Lacos

Bauexperte21 Jun 2014 21:38Good evening,
With all due respect, the window installer either didn’t get much sleep or is generally outdated in his thinking.
If you are building new, in my opinion, you should avoid the central mullion; there is nothing better than a full opening width. We have been installing mullion-free windows for several years already without any problems, whether Weru, Veka, or Kömmerling profiles. Especially with Veka.
He can’t do that, and if he tries, I would firmly call him out on it.

Our window installer wants to put a mullion in the middle – he believes that otherwise it won’t operate properly. A 2m (6.5 ft) wide roller shutter tends to sag and could be blown out during a storm (with a mullion, the roller shutter would be divided – i.e. two roller shutters of 1m (3.3 ft) each). We would prefer a mullion-free design with a narrow stile (currently we have this in our rental apartment, but without a roller shutter).

I have to join this discussion.
We also have some windows with a rough opening width of 2.01 m (height: 1.235 m). Our window manufacturer also suggested installing a mullion for this width to prevent the frame from sagging in the middle over time. We would prefer not to have a mullion, but we also don’t want the stability to decrease after several years. Is that actually the case?

I already mentioned in a previous post: No, it’s not the case; especially not with lift-and-slide doors (BRF). Up to a sash width of 1.135 m (3.7 ft) – this is absolutely no problem; anything beyond that, with triple glazing in particular, becomes quite heavy and should always be decided on a case-by-case basis – whether it is floor-to-ceiling or lift-and-slide doors (BRF).

We would rather not have a central mullion, but we also don’t want diminishing stability over the years. Is that really the case?

Sebastian7925 Mar 2015 20:55Construction expert, you made a little mistake – sashless would mean with a central mullion.
I just have the window contractor’s quote here, and we also have two sash windows.

Hehe... I’m reading the posts for the first time as well and I’m surprised because we also have with Stulp (if I remember correctly).
So without a mullion, double-leaf patio doors 2 meters (6 ft 7 in) wide, but... (I guess I’m the one who has now built with a rarity)... double glazing!
Our architect didn’t see any problem with any of it!
