Losses right foot crawling?

[dodo]

Hello,

In our house we have right feet at the level of the crawling at 1.60, which implies that behind the partitions it is an unused lost roof space.

I wonder if this type of roof space lost does not allow the house to overheat in summer and cool it in winter

How are they isolated, with care?
How does the air circulate outside and under the tiles?

for the moment it is insulated at the level of the concrete floor and at the level of the bulkhead on the roofed side.

I hesitate to redo the insulation as is where to recover this space and isolated at the level of the rampant.

insulated ... level of the bulkhead on the roof side.

And how many drafts destroying this insulation ???

and I do not understand his sentence very well, in particular the "allow"

should not read: "has no effect"?

I also think so: the smaller the isolated space, the less energy you use to heat it.

sentence too concise because true for the heat capacity by heating quickly, but a bad insulation makes lose the heat and therefore the nature of the insulator (thermal conductivity by surface on thickness) is more important than small or large; as well as the leaks by air current in the usual holes in the creepers insulated with the va va formerly (become invisible afterwards) !!

I say overheating because in summer the heat must rush into this part of the roof and vice versa in winter.

If well insulated like the rest, the heat or cold will not rush more than for the other rooms under the roof.

It all depends on the uniformity of the insulation and if it has faults !!

Certainly. My principle is of course "all other things being equal". (thickness and type of insulation)
