    After much searching last year I found a manufacturer of PIR panels in Spain (Gerona), Poliuretano S.A. When I phoned them I was given one of their retailers in France, Roofmart, who have several outlets here.

    Roofmart in Toulouse quoted 18€60 per m2 for 70mm panels of 600x600mm (R=3,05m2ºK/W)

    The stock name for the panels is PIR 5C, with the thickness required in mm.

    Well you have nearly halved the cost, now only €2249.86, I will still stick with 100mm fibreglass.

    In case it’s of any interest I just found the following company http://www.isolext.com which is quoting a price of €34.96 m2 for Recticel Eurotoit (minimum order 120.96 m2)

    The Eurotoit listed is Poyurethane (PU), not polyisocyanurate (PIR).
    Almost twice the thickness is required compared with PIR insulation.

    If anyone is interested, Googling “isolation pir 5c” produces several suppiers.

    Thanks nomoss. I hadn’t had time to check out all the details on the link I found – I’d started by looking at Tout Faire’s site which had Recticel Eurotoit 120mm with R5.2 but no prices.

    I’ll certainly follow up on the info you’ve given.

    I hate working with fiberglass, but having used the silver plastic sheeting a few times now in my opinion nothing can touch fiberglass. I do not care what the manufactures say like, this is space age tested by Nasa and caravan owners.
    If you want a warm cosy house get yourself down to brico and buy some rolls of fiberglass insulation and do not fit it wearing a tee shirt. :D

    nomoss – I’ve just had another quick look at the site I mentioned and it was 120mm Eurotoit with an R of 5 – this is the same R value as Celotex PIR (checked on a UK site)

    Still twice as expensive though so I’ll search as you suggested

    Sorry. I confused polyurethane with polystyrene, I haven’t really thought much about insulation since last year.

    I happened on this useful comparison http://www.starch.dk/private/energy/insulation.asp

    I ended up insulating between the rafters with extruded polystrene for the one small mezzanine room.
    For the the loft floor I blew in 30cm of cellulose insulation and floored it over with OSB panels.
    The house walls have 4cm EPS within the cavity walls plus 4cm XPS and 4cm GW on the inside.
    The house was incredibly warm last winter. We maintained a temperature of 20-22º in the main living spaces, using only our 9KW pellet stove, mostly on its minimum setting of 3KW.
    We shut down the stove every night about 11pm; by 8am the bedroom was around 16º and the living room 18º on the coldest days.
    We are currently using about 140m2 of the (single storey) house with the door closed to the part not in use.

    That silver multi layer insulation has had a bashing from the RICS, its members have been advised to re evaluate any inspection prepared using this insulation in a buying report and to downgrade accordingly.

    Although I have used it in my loft over fibreglass as a vapour barrier on the rafters.

    You have to order by the pallet, EG:  22 sheets 2.4m x 1.2m 100mm Kingspan 1116euro, or same dimension Celotex 990euro. unclear if this includes delivery…..
