Hello
We are currently building with a developer and will have a roof window installed.
We want to retrofit a roof window blind later (which the developer does not offer).
All of our shutters are electrically operated with wall switches.
My question is: What is the best way to connect the roof window blind?
Our roof window will be Roto, so we should use the Roto roof window blind.
Should it be solar-powered with remote control or electric with a wired power connection and a wall switch?
Our electrician only wants to install the power connection in a junction box under the insulation and sealing. This means that later the insulation and sealing would have to be cut open to pull out the cable and then resealed.
This resealing would probably create a weak spot in the roof.
Solar:
Advantage: no need for a power connection and no need to cut through the roofing membrane.
Disadvantage: you are limited to the remote control and cannot integrate it into smart home systems.
How does the solar function work? Does the battery get enough power constantly (the roof window is on the north side)?
Electric:
Advantage: always has power, can be connected to the same switches as the other shutters, and can easily be integrated into smart home systems with flush-mounted actuators.
Disadvantage: the power cable must be routed through the roofing membrane.
My question is, what would you recommend?
Does anyone know how to restore the roofing membrane to 100% watertight after installation?

However, the developer categorically refuses to run any pipes through the roof covering.
They even reject installing empty conduits anywhere through the outer layer.
We are only allowed to make modifications after the house has been fully handed over.
Once the house is completely finished.
But after full handover, isn’t it too late to install the collar, or am I misunderstanding something?

borderpuschl8 Sep 2022 15:31Oh dear, that doesn’t sound good, but it is just a guess. My concern is that the builder might not properly connect the roof window to the airtight layer (vapor barrier). Penetrations through the roof or through the airtight layer or membrane are common, for example for chimneys, ventilation, cables, or solar wiring. There is always a collar or the correct tape, sealing system, or flashing system for this. How does he handle your other roof penetrations?

borderpuschl8 Sep 2022 15:34Conduits are also potentially hazardous, but not because of sealing issues. Rather, temperature differences—for example, between the roof and the basement—can create a kind of airflow that leads to condensation.
I am afraid that otherwise no cables will be installed through the roof.
The roof window comes standard without a shutter and only a solar shutter is available as an upgrade (1600€ net additional cost).
If cables are needed from the roof to the basement, they can be routed through the utility shaft.
For photovoltaic preparation, we have a 40mm (1.6 inch) empty conduit from the roof to the utility room (200€ net) with a pull wire.
No cable for a roof window shutter was planned by the builder.
Only the electrician suggested installing an outlet next to the roof window where the cable can be routed, including a wall switch for 100€.
We just need to hire someone who can run the cable through the roof covering to the shutter.
