Energy-consuming house: 65m2 to heat !!

multi-layer insulation techflex top with rain cover

we can know the characteristics of this famous insulation ?
the rain screen is integrated?

[helium]

that's where it got
it seems to me that it is thermoreflector end insulator
it is rather a complement with 5 9 films (mixture of wadding, foam, synthetics, wool of sheep ...)
the type of people we put under the roof ...
(my poser is a carpenter!)
it is between 5 and 12 € the m2 at LeroyM ...
forcing cheaper than hemp
but I see him next week to negotiate something else

quote cladding + insulation not encouraging: 25 000 €
(including 9548 € finished paneling (?))
supply and installation spacer 120 * 40
cellulose wadding Dammstatt Cl 40 ep 12cm
European approval number ETA04-080
fire classification M1 48kg / m3
iso high density wood fiber 15mm
finishing paneling ep 20mm

It was not bad, but:
- The FlexCl panel wadding (this is the panel that we propose?) It is horribly expensive ...
- € 9548 (or € 87 / m² if I'm well?) For "paneling" is port'nawak! Even for a good cladding it's far too expensive!

Otherwise the shot of the wood fiber board to close the frame is interesting: it is a rain-proof panel that will at the same time cut the bridges of the frame, for cons it is more expensive than a rain cover film (and it adds to the thickness).

For cotton padding under pressure, I would go much further than Jamo: I never put it in this form because to be really sure that it does not cup, it is necessary to go up to 70 kg / m3 and it's too much ... Too much matter, too dense (the lambda goes back up ...).
Suddenly, for cotton wool wall is wet projection or nothing!

and isover GR glass wool + aluminum in 100mm for a R = 4,55
that's good?

elio, if you want LV, take the rock wool because + dense
mechanically fixed.

55 kg / m3 no compaction, checked and reverified, 2 weeks without
siding, it did not move.

As a pro, I can not take that risk.
So be denser or not at all ...

NO ! The one who sells you this tells a huge stupidity, because it would be a lambda 0.022 which, unless to create a material that traps rare gas (argon ...) or vacuum (! ) is physically impossible!

Hello Woodcutter
these are the recommendations of TA, if you put more dense => + expensive.
so 55 kg (+ 10%) is more than enough, it should not be too dense either.

[helium]

you do not take the lead ...
the guy offers 40kg I'm going to ask him 70kg ...
he will double the bill and put me 50kg
and I would not have the means to control the dose

What TA are you talking about?
From an ETA or TA from a mark passed by CSTB?

This figure does not come from an AT at all, but from the experience of people who have been applying wadding for more than 10 years.

Two scenarios: either you are a professional and you do not take any risks (decennial insurance and not "in 2 weeks it does not move ..." ) so you put the density to guarantee a stability of the product, either you are particular and you do what you want!

I explain the pro positioning, a point is everything!

Elio, 40 kg are panels, but surely not insufflation.
