2m wide terrace door without a central post recommended, warranty?

Hello everyone,

we are building a single-family house with our general contractor. In the living room, a 2m wide terrace window / terrace door (triple glazing) is to be installed (profiles Salamander).
Our window installer wants to put a post in the middle - he believes it won’t work properly otherwise.
A 2m wide roller shutter tends to bend and could be blown out during a storm (with a post, the roller shutter would be divided - i.e. 2 shutters of 1m each). We would prefer a design with [Stulp] without a post (this is how it is currently in our rental apartment, but without a roller shutter).

The window installer does not completely refuse the installation, but if we stick to our decision without a middle post, he would deny warranty coverage for the fittings, the frame, and the roller shutter.

Now I have the following questions for you:
1) What is your opinion on this? Is our window installer right or just being overly cautious?
We certainly do not want the rather wide roller shutter to bend.
2) Do you have any experience with such a wide window? What should be demanded from the window installer during installation (reinforced profiles, etc.)?
3) Can the window installer simply opt out of the warranty like that?

Regards and many thanks,
Lacos

My parents have had a 4m wide, floor-to-ceiling window with a large roller shutter for 30 years, and it is still the original one, so it has survived every storm (and even during the last severe weather—we live in NRW—there was no problem with it being closed). No idea, however, what brand is behind it.

I have an approximately 3 meter wide floor-to-ceiling window in my apartment (3-part with door) that has a roller shutter across the entire width and has had no problems so far. All other apartments in the building have similar window fronts, and each had a single wide roller shutter installed. The building has now been standing for 10 years.

The only thing that distinguishes these wide roller shutters from the other windows is that the drive is electric due to the higher weight.

Thank you very much for your contributions. It also seems strange to me. The question would be whether certain demands (of course associated with an extra cost for us – but that would be okay) can minimize the risk. Any reinforcements or thicker armor?! Maybe a professional will respond here who can give me certain specifications for the window maker. Changing the window maker is unfortunately not an option.

Hello,

that is strange! Why does the general contractor talk about bending the blind but wants to take away the warranty for the blind, fittings, and frame? Does the blind pull the frame away or what? We also have 2.40 meter wide floor-to-ceiling windows with [Stulp]. No problem at all! Well, we chose aluminum blinds to ensure burglary protection during vacation (takes longer than plastic) and so that they don’t sag after years.

Was the window with the blind already part of the contract at signing or was it added later? If it was planned that way beforehand, your general contractor should figure out how to manage it without any disadvantage for you. I would ask him why he wants to make his problem yours.
