ᐅ Temporarily sealing structural openings

Hello everyone!

For our new single-family house, the shell is mostly finished, and next week the roof frame will be installed and covered. Unfortunately, the delivery of the windows has been delayed, which means the building would remain open for about 4 weeks.

During this time, the electrician and drywall installer could still work. However, since the house would be easily accessible and this poses a security risk (theft, etc.), the question is how to temporarily secure the window openings? I was thinking of using OSB boards on the ground floor and plastic sheeting in wooden frames on the upper floor.

1. Do you know of any other methods for temporarily closing the openings?
2. Would it be too dark inside for the electrician and drywall installer, or can they still work under these conditions?

Thanks and good luck!

The electrician can come for at least 2-3 days to mark and chase the walls. Personally, I have also installed cables without the windows being in place. He doesn’t necessarily have to use the expensive CAT cable right away. In a standard single-family house, the electrical cables don’t cost more than 1000€ (about 1,100 USD). It’s usually not even worth stealing any of it.
Whether they do it or not also depends on their workload. I would just give them a call, but don’t worry too much.

Often the electricians don’t want to come inside yet because they want to leave their tools there to avoid carrying so much the next day.
I closed it up with OSB, but in my case, it was only about the front door, stairwell window, and guest bathroom window. So darkness was not the issue...
But yes, talking to them is the easiest solution.

Thank you for the answers! The craftsmen are in favor of a closure. The question about the closure method (next to OSB) is still on my mind... do you see any other options from your perspective?

We will at least secure and make one room airtight until the windows arrive. This way, tools and other equipment can be stored there.
