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,
Thermal bridges are not dependent on the season. The same effect could be achieved with exterior insulation and additional partial interior insulation to reduce the cavity effect.

.. The reason for this is that the so-called thermal bridges (rafters) no longer hold up in summer.

Hello €uro,
Would you recommend the following insulation based on the topics mentioned above?
LINITHERM PAL N+F – efficient thermal insulation for new builds and renovation projects
LINITHERM PAL N+F features a double-sided coated aluminum foil facing – non-glare and tear-resistant. It acts as a vapor barrier, reflects the sun’s radiant heat, and protects occupants from electromagnetic pollution.
The high-performance rigid PUR/PIR foam insulation provides excellent thermal insulation not only in winter but also keeps heat out during summer. This ensures a comfortable indoor climate all year round, even under the roof.
Thanks to the specially designed all-around tongue-and-groove compression joint (N+F) and the additional longitudinal tongue-and-groove connection, each installed panel immediately creates a thermal-bridge-free, airtight and windproof underlay (seal transverse joints with joint tape). The robust edge profiles enable efficient and cost-effective installation even on complex roof structures.
Cut pieces formed around dormers and valleys can be rotated and reused.
Thank you very much for your advice.

Hello,
WB (wood-based insulation boards) are not limited to a particular season. You can achieve the same effect with cavity insulation combined with partial internal insulation to reduce the cavity effect.

Hello,
With exposed sunny locations, I would avoid a half story and build two full stories, if this is allowed by the building permit / planning permission.
If the half story as well as the above-rafter insulation are chosen for any reason, I would prefer products made of stone wool.
Best regards.

Hello €uro,
According to the building regulations and submitted plan, we are required to have a gable roof with a pitch of about 30-40 degrees. We have a knee wall of 120 cm (47 inches), which results in hardly any loss of usable space.
As already mentioned, we want to leave the beams exposed and cover the rafters (outer side) with tongue-and-groove boards, followed by insulation above the rafters. The roofer said that with the product "LINITHERM PAL N+F," no additional membrane is required.
Why would you prefer stone wool?

If the half upper floor and insulation above the rafters are already planned for, for whatever reason, I would prefer products made of stone wool.

dachspezi16 May 2010 23:01Hello home builders,
I am a roofer and always recommend LINITHERM PAL N+F to our customers because I can confidently stand behind it. I use it myself. I have also installed roofs where the rafters remain exposed. The customers, just like all the others, are 100% satisfied. Thanks to the aluminum on both sides, it provides protection in both summer and winter. You just have to install an airtight membrane for airtightness and connect everything properly; otherwise, no insulation makes sense. The membrane is mandatory but has only been required since 2009 by Linzmeier due to the new energy-saving regulations. So, I would say you are on the right track. For any other issues, there is a solution from Linzmeier or from your roofer.
If you have any questions about Linzmeier, feel free to ask—I have a lot of good professional and personal experience with their products.

Hello Dachspezi,
thanks again for your expert opinion. That helps me a lot. How should the insulation assembly and membrane installation be structured?
From inside to outside:
- Installation of tongue-and-groove boards on the rafters (outer side)
- Then the airtight membrane
- Linzmeier LINITHERM PAL N+F insulation boards
- Installation of counter battens and roof battens
- Then the roof tiles
Is this setup okay?
