Hello dear all,
we live in an old building from around 1930 and want to convert the attic (living room/bedroom). Now I have already gone through various forums to learn more about the structure of roof insulation – and I am now totally confused.
I will write down how I would do it based on what I have read everywhere... from outside to inside
1. Tiles – they are all still good – some would need to be repositioned and any larger holes can be sealed with mortar?!
2. diffusion-open underlay membrane -- I have already bought...
...The diffusion-open high-performance underlay membrane is particularly breathable and can be laid directly from the roll, directly onto the insulation or wooden construction. Through the special functional membrane, a high water tightness with very good diffusion properties is achieved. Thus a DIN-compliant full-rafter insulation can be carried out. Product structure:
Material fleece: polypropylene Color: white Area weight: 105 g / m² Temperature range: -40 / +90 °C Sd value: <0.02 m Exposure to weather: 3 months
this is glued with this special adhesive between the beams and then wooden battens come on top (so: beam adhesive membrane wood batten) where the membranes overlap, connect with special double-sided adhesive tape
3. Insulation wool 200mm, cut, stuff in
4.1 wooden cross battens for stabilization? I know that the insulation wool is clamped between the beams; but can’t it still fall down? 4.2 Vapor barrier foil (does it then also have to be diffusion-open?) The wall connections of the foil are also glued with special adhesive for masonry.
So, is this correct now? Did I forget anything? Any tips?
We are not in a hurry with the conversion, but we would like to gradually get the materials and inform ourselves a bit more...
Many thanks for the following answers
