Not necessarily. If one of the layers of the wall already provides an airtight seal, then the wind on one side cannot move the air trapped in the entire thickness of the straw, it can just quickly renew the layers of air close to the outside, which reduces the "real" thickness of insulation.fowleil wrote:Yes but you agree that the insulation could be great if the plaster is not there (which is the case) it would be a null result !!!
With 38 cm of straw, you must have boots placed on edge, I suppose?fowleil wrote:Walls = 38 cm approximately and for the already coated face 42/43 cm
Roof = insulation of wood wool panels 20 cm
Slab was carried out in a conventional way (ie not especially ecologically) and the floor of the floor is lined with hemp panels.
The interior partitions are insulated in cork.
The windows are double glazed 4/16/4 low emissivity and of course wooden.
If so, that gives you a fairly interesting thermal resistance, around 8 m².K / W.
For the low level, I don't know with the info you give me and for the roof, it is apparently the "weak point" since it will have a resistance of barely 5 m².K / W. Is it airtight?
Are your windows with an Ar blade?
I actually think that if the production is of good quality, you can switch to BBC, ie less than 50 kWh / m² / year.
