  1. Slight thread drift but.........we bought some, 6 for 18 euros and one for 50 euro. There was no difference in longevity or performance price wise but overall they were less than promised on the packaging in terms of lighting.

    Successful use of solar lighting ? Anyone got any comments ?

  2. Araucaria i stand corrected thanks, I put it down to the Fen pronunciation of the word as i have never seen it written down. Having googled a load of stuff re this i think that our build is almost like cob construction ......see here:

    Be fascinating, not to mention cost effective, to build a house like this nowadays...almost a Passivhaus !!

  3. Hi

    We own an old mas in Provence. The way it was built was basically a mixture of earth, stones and lime, shuttered up to a metre, let go off, then continue...........it is typical of the area........it's a bit like clunge build in the UK.

    It is most effective........I can testify... if you try to jack hammer it is exraordinarily tough.

    Does anyone know the french for this type of build. Google doesn't translate clunge !!

    Thanks W
  4. Hi.........need a bit of advice. I need to install some sort of pump to augment the pressure in domestic water system. We have a B&B and when all 5 showers are on the go I have no-where near enough pressure.

    Any advice on installation, can it be installed outside to cut noise ?, make and types of pumps and ball park prices

    Cheers Wilko
  5. Théière........where on Superquilt's site does it say it has passed the hot box test ? i can't find it.

    It still needs to be used in conjunction with other insulation and when doubled up they don't show any thermal figures.

    you have to install with a 25mm air gap either side and when you staple it to the beams you create a cold bridge.

    I think the Germans have got it absolutely right right.

  6. The download form the link below

    Conclusions 6.3

    A model developed for the prediction of multi-foil system thermal behaviour indicates that the level of performance achieved even if the best possible materials were used in its construction, silver coatings with an emittance of 0.02 and foam core materials with a thermal conductivity equivalent to aerogel blankets 0.012W/mK, they do not obtain a lower U value than 200mm of mineral wool insulation.

    Yet Actis/Trada says:

    The assessment indicates that when TRISO SUPER 10 is used as specified in the

    manufacturers “Fixing Instructions” (Product Application Guide, Ref: PZ182 and

    Technical Data Sheet, Ref: PZ177), the thermal insulation value is equivalent to

    mineral wool (glass) of 210 mm thickness.

    I guess it’s up to the reader as to what you believe but I won’t be using multifoil in any build soon.

    Spot on. If we are to assume that people use the products that they make and/or sell does this mean that the workers who make Rolls Royce's or Ferarri's should all be driving around in them, of course not.

    Thanks for that very valid and relevant point Quillan bit like all the people that work for NASA flying around in space shuttles.

  7. The link is to a thread on the Greenbuilding forum which has been running for 4 years re multifoil insulation.. This link should show the last page and a couple of guys have posted an overview, saves reading the previous 800 posts. It doesn't appear to fulfill it's promises.

    Incidentally one of the posts said that the Actis factory wasn't insulated with their own product.
