House construction, please provide decision aids for the details

Hello SierraSix,

We have a similar plan to you. We also have the roof open to the upper floor. However, our roof is still covered with "standard tiles." We have an asymmetrical roof, and on the flatter side, it is 18 degrees.

We have already lived in a similar apartment. The noise level is actually not so bad, as long as you don't plan roof windows or skylights on a flat roof (in my opinion). You can definitely hear the pattering of raindrops on roof windows.

I would forgo a roof window in the bedroom, despite the perhaps once-in-a-lifetime view of the starry sky. However, I could imagine that if you are building two stories, you probably have given up on roof windows anyway!?

Best regards

Fanta

Morning Fanta, we only have roof windows in the bathroom and hallway simply to provide "MORE" light there.. hmm as I said, with the roof pitch I really have to give up, unfortunately. I just couldn’t reach the architect today.
I know about the noise with glass, I also slept under a roof window for a few years.
That’s also why I “fear” that with the “resonating body,” meaning with an aluminum roof, practically the whole roof would be like a HUUUUGE window!! :)

And as I said, the architect said that due to the pitch, practically only these two systems are possible.

That’s why I thought maybe someone has had positive or negative experiences with this "fiber cement" or with the aluminum shingles..

What I also found out earlier is that with the aluminum shingles, you only need to ground the roof itself and so you can save the separate lightning conductor installation. ;-)

Hello Sierra,

is the roof pitch very steep or very flat? We have a roof pitch of 48 degrees - which is quite steep - and we have normal roof tiles (Harzer Pfanne). Just for your information.

Regarding your heating system, I would check locally to see which brands are available. We originally wanted Buderus, until we found out that within an 80 km radius there was not a single Buderus dealer. This makes the travel costs very high in case of need. So we decided on Viessmann, as we have a large selection of specialist companies nearby and, as the saying goes - competition keeps the business alive and lowers prices for the consumer ;-)
When choosing, also pay attention to the values. Do not undersize and make sure the modulation starts at a low value (around 2 or below). This saves heating costs - meaning gas - in the transition months, when you don’t need the heating that much anymore. A heat surface calculation provides good insight into what the minimum requirements will be. But always remember – this is calculated for about 20 degrees room temperature. So if you want more and choose a gas boiler that only covers the minimum, it can happen that it won’t get warmer. For us, a Vitodens 200 was supposed to be installed. After doing some research online and at trade fairs, I changed that to a Vitodens 300. Why? Different burner with a broader modulation range and better burner performance. I have never regretted spending the extra 500 euros to date.

Best regards
