Raffstores - which manufacturer? What differences?

You can't name prices per m2 there, I've learned. It depends on too many factors how the surcharge turns out. You definitely save money if you have as few blinds with few motors as possible. For example, if the fixed element of the sliding door and the fixed glass next to it only had one common blind (if the width allows) and also only one motor. I just went through the upgrade myself and would say roughly around 350€ net surcharge per blind. But I don't need a wind sensor; if you want one, certainly 500€ more plus electrician. I previously had roller shutters, electric, plastic (large glass fronts were already calculated with aluminum) in the plan and offer. They are made of aluminum anyway. The color was freely selectable from the RAL palette with no extra charge. Unfolded is the cheapest; I would choose folded and guided on rails. To prevent twisting/damage and to avoid rattling in front of the glass. You have to think about the box. The roller shutters were planned with a top box, so it was obvious to do the same with the venetian blind. Because it does not require any structural changes to the building itself. For the surface-mounted box, you need masonry behind it, I assume. We were also offered boxes integrated into insulation, but then the glazing would have become floor-to-ceiling. We lacked the money for that, and plastic as a system would also have reached its limits. Basically, I find top-mounted good because the thermal insulation is best preserved that way. We have the manufacturer Climax with T slats. A kind of middle ground between round and Z. Climax, by the way, manufactures the slats for the big German brands ...

I don’t think that will work. Connected it would be 7.3m.

I don’t need a wind sensor, if you want one it will probably be 500€ on top plus electrician.

I asked my neighbor earlier. He hasn’t had a rain sensor for 2 years but will probably get one soon. We’ll see, maybe retrofit then.

You have to think about the box. The shutters were planned with a top box, so it made sense to do the same with the venetian blind, because this doesn’t require any structural changes to the building itself. With a front-mounted box you need masonry behind it, I assume. We were also offered boxes integrated into insulation, but then the glazing would have been floor-to-ceiling. We couldn’t afford that and plastic as a system would have reached its limits anyway. Basically, I find top-mounted good because the thermal insulation is best preserved.

We are still free here. I have to tell the shell builder in 2 weeks where I want the shutters and venetian blinds. Something is missing in this dull anthracite/white concept (plaster/windows) that breaks the visual boredom.

What is the cheapest overall package of the components?

- Unrolled
- for now without wind sensor
- rail-guided unplastered

Honestly, I don’t find it unattractive at all that neither the guide rail nor the box are plastered.

I have scheduled an appointment with my window maker for Monday. I would still be grateful for further input.

Just stick to mounting boxes. Then you can have roller shutters as well as blinds without changing the building. The window manufacturer will tell you the additional costs.
If mounting boxes are interesting to you, you have to hurry and shake the window manufacturer to get prices.

Unboxed without rail is the cheapest. Two out of three window manufacturers contacted only offer rails now; everything else just causes trouble.

The rest is a matter of taste. Apart from the fact that we take a lighter gray instead of anthracite, we also have panels on the facade, and in the front garden area with carport/garage we clad with wood.

What is more cost-effective, a flush-mounted or surface-mounted box?

I can't say. The roller shutter box was my starting point and the upgrade to [Aufsatzkasten Raffstore].

The facade builder wanted about €280 net per piece for the thing integrated into the insulation. So just the installation box with labor. Something from Brillux.
