Hello
we want to insulate our roof ourselves. We have a few questions.
1. What materials are needed, and what is the typical roof construction (from outside to inside)?
2. Which type of insulation wool should be used if we plan to convert the attic into a room later? There are different thicknesses and some have aluminum foil on the back, while others do not.
3. How much did it roughly cost you? We need to insulate about 223m² (roof area to be insulated).
Best regards

Hello KPS,
Thank you very much for your reply.
The aspect of sound insulation you mentioned has not been taken into account by us so far. OK, we also live in a rural area, so external noise levels are limited.
Is there a calculation method for this, and how does it manifest specifically?

However, the chosen option is expected to have higher costs as well as poorer sound insulation performance compared to insulation installed between rafters.
Kind regards,
KPS

Hello,
Yes, summer heat protection is mostly neglected.
Best regards.

...Possible alternative options (for sound insulation and summer heat protection along with their respective costs) can certainly be presented by the planner.
Yes, summer heat protection is mostly neglected.

Hello €uro,
what exactly do you mean by that? What do you mean by summer thermal protection?
I can’t gather any constructive insights from your comment!

6Richtige11 May 2010 14:27€uro thinks, in his opinion, that while new buildings usually focus on minimizing heat loss from the house, less attention is paid to preventing the house from overheating in summer. This is especially important for prefabricated houses. Window shading, appropriate wall construction, and issues in the attic caused by condensation, etc.
Hello,
It was simply a reminder of an important aspect to consider! As 6Richtige mentions, everyone focuses on thermal insulation in winter. The summer heat gain, especially in the attic, is often overlooked. Current verification methods generally exclude opaque building components from this assessment.
This issue is particularly relevant for pitched roofs and locations with strong sun exposure.
In 2008, I conducted measurements on a sloped roof (west-facing). Temperatures above 60°C (140°F) were recorded above the insulation between rafters. This represents a significant "heating potential," considering the surface area involved.
Best regards.

haeuslebauer11 May 2010 19:11Which option is better now
Hello €uro,
which insulation is better to properly address the issue of "SW"?
As a layperson, I would choose exterior rafter insulation. The reason is that the so-called thermal bridges (rafters) no longer exist in summer. Or am I mistaken?
