"superquilt" roof insulation.
I have just seen some 25mm quitled roof insulation, that says it acheives 0.2 U value, its about the same price as 100mm kingspan, which is also about the same U value. Does it work ? Its goona be much easier "materials handeling" than kingspan, and thinner. Neither product I have seen claims a BBA certificate. I am not sure a BBA certificate means much, I have had products with certificates fails, and the BBA arn't intereted ... Rick |
I too was interested in this last year. However I'm yet to be convinced.
The opposition don't agree.... see.. http://www.celotex.co.uk/pdf/Multi-foil_Bulletin.pdf In response to this the company in question had some independent testing done. Last December I asked them for details of how the test were done. They sent me ... http://makeashorterlink.com/?K6DA127EA and http://makeashorterlink.com/?R6EA537EA However these do not describe the test in detail or how it's performed... When I pressed them for details they said.... "Sorry, no, these are not for public release" I have no idea if there have been any further developments dince Dec 04.... Roy |

Does it work ? not bubblewrap is it? Put it this way, you know insulation works by trapping air and keeping it still... what is so vastly superior about this product compared to glass wool? How exactly does 1" of it trap and keep still more air? NT |

There's been a lot of debate about this stuff and the methods used for testing it. A lot of heat loss is by radiation and the multilayers of foil separated by foam cut this rather dramatically. It's not cheap but if your space is limited it could be a good option. In the cryogenics field where vessels containing liquid nitrogen or even colder substances need to be kept very insulated from the environment, multifoil blankets consisting of 30 layers of foil and paper per inch are used. |

Yes.. What concerns me is that it does not seem possible to get details of exactly how they do the testing of this stuff. If they published the details of the method and the results it would help me make up my mind. See my earlier post.. Roy |

It's called Tri Iso Super 9 made by a French company called Actis. The previous owners had boarded under the rafters and partially insulated with polystyrene, but it was freezing in the winter. I didn't fancy ripping it all out and installing celotex between the rafters, or installing celotex under the rafters as that would have lost too much height. Then I found out about the Tri Iso Super 9. I just stapled it to the existing plasterboard, put battens on top, then more plasterboard. I've only lost about 3 inches of height and the room is significantly warmer than before. To be fair, the extra warmth is probably also due to better draught proofing and repositioning the radiator.

A lot of money for bubble wrap. _________________________________________ Usenet Zone Free Binaries Usenet Server More than 120,000 groups Unlimited download http://www.usenetzone.com to open account |

bubble wrap. But Tri Iso Super 9 made by a French company called Actis is not bubble wrap. If you study it from the point of view of a theoretical physisist you may conclude the manufacturer's claims are likely to be correct. Making your own with several layers of cooking foil and craft paper would, of course, be much cheaper. |

If you study it from the point of view of a theoretical physisist you may conclude the manufacturer's claims are likely to be correct. They claim the equiv of 200mm of Rockwoll in performance. No independent test confirms this. A foam maker slags it but will not give full details of their test. The jury is out. One organisation in Florida concluded that radiant barriers are good for keeping heat out, in the attic. Other tests in the US say is performs badly in cold climates. Any benefits are likely to be draft proofing and a small amount of insulation from the bubble wrap. Very expensive for so little. Beware!!!! Making your own with several layers of cooking foil and craft paper would, of course, be much cheaper. And probably as effective as the vastly overpriced Tri Iso. If this stuff does what they say, It would have it in the loft tomorrow. _________________________________________ Usenet Zone Free Binaries Usenet Server More than 120,000 groups Unlimited download http://www.usenetzone.com to open account |

But if the main loss mode is through convection it won't. In a vacuum the first is true and I would imagine some satellites are insulated with something like this. |

It is not independently tested and verified by a credible organisation. Just wild claims. _________________________________________ Usenet Zone Free Binaries Usenet Server More than 120,000 groups Unlimited download http://www.usenetzone.com to open account |

The Celotext description of the NPL test showed that it actually did work (for some value of work). |

Price/performance. If it does what you want going by these Cellotex test, then if the price is right, then it is fine. Currently it is "very" expensive for what it is. _________________________________________ Usenet Zone Free Binaries Usenet Server More than 120,000 groups Unlimited download http://www.usenetzone.com to open account |

I'd guess it's as good as 200mm rockwool when used under the floor, but only as good as 90mm rockwool when used in walls and as good as 60mm rockwool when used in ceilings. OTOH for preventing solar gain in ceilings it would be as good as 200mm rockwool. All these would require ~25mm airgap either side. Probably comes into it's own for insulating uneven or odd shaped gaps and cavities, especially where a vapour barrier is also required or a gap for ventilation. cheers, Pete. |

When that's off it does nothing. but only as good as 90mm rockwool when used in walls and as good as 60mm rockwool when used in ceilings. |

A builder has just installed this stuff in the roofs of two new houses next to me, interesting looking material, the builder hasn't spared any expense on the rest of the build and had plenty of celotex on site which he used for the floors. He's convinced that the quilt is the dogs gonads as far as over the rafters type of insulation goes. Bertie, has he any figures to prove the performance? Or does he just wave his arms when explaining things? _________________________________________ Usenet Zone Free Binaries Usenet Server More than 120,000 groups Unlimited download http://www.usenetzone.com to open account |
