Hello
I'm studying how I will be able to insulate the attic of my house effectively.
My roof is about 120m². The insulation dates from about 1985.
There is glass wool between rafters on 8 cm thick.
No under-roof screen.
Photos while working in 1984 or 85
We live in this renovated house inside
Photos today
Not wishing to break all the placo I would like to do an isolation from the outside.
The big problem is that the ditrance between the tiles and the placo is only 10cm visible on the photos of time.
Can not accommodate two crossed layers of insulation without doubling the thickness of the rafters to reach a coef R of 5 see +.
I am thinking of the solution of self-supporting "sarking" insulating panels.

What do you think of this system?
I can also add my old glass wool in the concervant?
A priori it is necessary to count on 60 € the m² for the panels self-bearing there is solutionsd cheaper and equally effective?
A simple multilayer insulation also acting as screen under roof would it not be as effective and less expensive?
Should we strengthen the frame?
Is it possible to obtain panels without interior siding (economy of price and weight) since my placo is already existing?
Thank you for your help if there are specialists.
Need help with living space insulation (Sarking)
In any case these panels are very effective: it is what we put in a mezzanine and the room remains fresh at the moment (Martigues 30 ° and even end of August). I was really surprised (positively) at the time of the work we had removed the dubbing (directly under the tiles it was glass wool) and it was untenable in this same room

Yes it's the same at home with only 8 cm of glass wool is not much better than nothing.
I have already noted 31 ° C in the bathroom facing south.
In addition I have a large Velux facing south in a room.
I plan to replace it with a triple glazed Velux.
I wonder if it's even better to replace it with a smaller model.
How much did you cost this renovation?
Do you do it yourself?
As you used the Thermotile, I saw that it is very well adapted for verandas with tiles Romanes?

no, I did not do it myself, it's a mason who had worked for my in-laws whose work we knew
for the cost I must look because it is in a set of works: there was removal of the cover, some work of leveling of the wall of supporting the panels to pose, raises panels and delivery of the cover on 16 m2 on the ground (about 20 m2 on the roof).
These are 12 13 Compressed Foam Panels cm thick.
for the cost I try to look at it tonight, I go to the construction site to see the owner hands-dad (it helps that he built homes for 22 years!)
another significant advantage, this part of the roof becomes dust and rodent-proof (the glass wool was directly placed under the tiles)

small up to give the cost:
18m2 ground surface so a bit more for sloping roof:
the service includes the removal of tiles, the laying of plates and the laying of tiles + some masonry work at the level of load-bearing walls for upgrades: 2000 € HT.

I have not started work yet but I will not do the insulation with rigid panels.
My house has dogs sitting on the north facade so this prevents the panels from being laid.
The panels will raise the cover of 15 20cm, so we should raise the windows all the way and resume the frame. Without raising the dogs sitting the panels will arrive in the middle of the windows. It's a question of budget.
I will therefore opt for thin insulation.
Firstly turn the old glass wool, put a good modern insulation and eco kind of wood wool, put a thin layer of insulation under the roof, to avoid air infiltration when there is wind, change my old windows single glazed by triple.
I have already bought a window Velux comfort (not found in triple glazing) with awning.
I'll ask it in a few days.

I think dogs sitting at overheated level in summer is better than velux.
What does not you hear about thin insulation?

That's right with me there are 2 dogs sitting on the north side and a skylight on the south.
The velux in the south is not a good choice but I'm not going to redo a dog sitting, with an external blind I will reduce the magnifying glass effect of the velux window. The thin insulation is rolls with aluminum foil and multilayer insulation in white sheets in general. It is not really insulating but it will cut wind while letting the roof breathe.
