Thermal bridges and wooden frames: insulation pub




by I Citro » 03/09/07, 00:06

I have just received a bundle of advertising coupons with my new directory.

This caught my attention:

I thought that wood was one of the best insulators and therefore did not cause thermal bridges ... :?:

If anyone can explain to me ...

: Cry: Sorry, my image does not want to be displayed ... if a modo goes there ...

In the ad it says:
"Blowing rock wool is the best insulation for remove the thermal bridges caused by the wooden parts of the frame."

What do you think? :?:

:? Thank you camel!

It was the spaces.
By cons I also find that the image is too large ...
it weighs, however, not heavy; only 130kb

The latest news is that wood is an insulator. Therefore, I do not see how it causes thermal bridges ...
Maybe because it is less good insulator than rock wool ?!

In any case, I have never heard of a thermal bridge with materials other than metals ... Could I have been lied to ?! : Mrgreen:

I have the impression that these rock wool suppliers say anything to sell their products ...

Such incompetence (at this level it is not a mistake it is a professional fault) discredits the Qualibat logo right next to it ...

Hello

A frame constitutes only a framework (beams, purlins and rafters ...) capable of accommodating a roof (tiles, thatch, slates ...)

and as it is the whole even in wood is not really at the top level insulation.

And it is for this reason that we mainly isolate according to the two processes mentioned

Panels placed against the frame
Loose wool on the floor of the "attic"

We agree: the attic (whatever their structure) constitutes a very important part of the heat losses (30 to 40%) there is not the debate.

What shocks us is the fact of citing "wood" as a thermal bridge.

Besides if we think a little and following the very definition of a thermal bridge, in the attic it simply does not exist since the beams are covered by the roof ... am I wrong?

hi Christophe

The thermal bridge that hurts, it is clear that it is:
indoor air + roof + outdoor air and in no case the wooden beam.

So two observations:

The guy who spawned the text or doesn't know much about thermal bridging

The two solutions he offers are valid

if he masters the laying techniques
better than the thermal bridge : Mrgreen:
