Hello,
I am currently in the process of doing the metal strips for our insulation, suspents/furreurs.
We are going to be using 20cm insulation, as that is what a lot of people around where we live have and was also recommended for us.
I am just wondering what other people used, and whether ifferent parts of France differ to what mm of insulation they use.
I am also wondering, proberly a silly question, does it matter what side of the insulation goes where? Is the paper type side just for handling, so you dont get more ichy?

Shezzar, 1. I've once found recommended insulation thicknesses for different regions of France. 2. The paper provides a certain vapour barrier and must therefore placed on the inner (warm) side of the insulation to prvent condensation in the insulatioon. 3. I've placed a rudimentary description of roof insulation on my website, in text (dutch) and photographs and drawings. |

We are in the looonnggggg process of insulating our loft area (after having re-opened all window openings and fitting Chesnut window frames/double glazed and a few Velux). We went for "Laine de Bois" (manufactured by Holsflex a German Company) which in our part of the world (Tarn & Garonne) will keep the heat out during the day (called dephasage). 80mm sheets cut-to-size between the rafters and 200mm on top of that. As our rafters are non-standard and bend all ways, it was tedious work to check the distance between joists every 30cm in order to report this dimension +20mm on the new sheet to be cut to shape (using a basic electric carving knife to carve a neat line of cut through the wood fibres) then forced between the rafters. The 200mm Laine de Bois will (should) be easier to put in place but project stopped this August when I noticed I needed to buy 200mm screws to hold the sheets in place before we instal the railing, plastic sheeting and plasterboard go on.
Always very hard to plan a job many miles away and I'm not buying 200mm screws in France, I would need a Bank loan !

Yes we are using 200mm laine de verre for out job, I have already got the metal feurrurs up just straightening and strengthening them at the minute.
Than its time for the ichy job of getting it all in place.
Yes I have found a slight difference in price of screws, but I have only had to get small screws so not worth getting them imported,so to speak.

Where to find the relevant info? It's the opposite of finding a needle in a haystack: so much information around, on the internet specialised websites and forums, an increasing amount of books and the regular special issues of French magazines as SytèmeD. For books you could do some windowshopping at the website of the Eyrolles publishing company. Because everybody wants his or her information for free in these internet days, there is another option I should mention. There is a more than excellent Scientific and Technical Center for Building here in France, the CSTB. Wide range of independent research, books and freely available online information. This study about Isolation thermique des combles is one of the many examples of what they can offer. With a google search you waist a lot of time in filtering, separating the good, the bad and the ugly. Starting your search in such a center of excellence can be a shortcut. RA |
