Spray foam insulation
Yes its not very breathable falls off pushes off tiles and pongs lot as
well. bah humbug. My loft however is open to the elements, ie you can, if I could see see out between the times. It seems that no lining was ever fitted as there is no evidence of fixings. The good thing is that it does not have rot, the bad thing is the wrong type of snow powdery, gets in. And muck. Brian -- ----- -- This newsgroup posting comes to you directly from...

Mike If its the foam that you refer to is the one that is sprayed to the back of the roof, tiles and lath, it will be the biggest mistake you'll make. If you ever have to do a repair or a slate or tile gets broken, its a very expensive job to do, that if any roofing company will take it on. |

But probably not wood and tiles which it what the foam destroys. trapped water rusts steel as well as rots wood. Wood & steel covers most roofs. NT |

It also traps water against the timbers & makes them impossible to inspect. A crazy idea. NT |

[1] Foam sprayed to the underside of the slates gluing them to the rafters/purlins Same situation with my brother's roof - neighbours had been sprayed with this stuff, but fortunately my brother's hadn't. When the roofer did my brother's, he warned him that if he spoke to the neighbour about having his done, it would be *much* more expensive. Reason is that it apparently takes 10 times longer to strip the roof, and only then will you find out how much of the structure (e.g. rafters) needs replacing. Also, old roof tiles can't be used as hardcore as they can't be separated from the foam and battens, and you end up paying to landfill them, and the volume is always very large. -- Andrew Gabriel [email address is not usable -- followup in the newsgroup] |

Mike I don't think anyone here has been unwise enough to use it NT I had my corrugated cement / steel purlin roof of my barn, which I was turning into a workshop, foam sprayed 9 years ago and it has been absolutely excellent. We aimed for 100 mm on the roof and 75 mm on the walls, which were then faced with 18 mm OSB3. about 40 x 40 foot and it was around £4K then. My only regret is that they failed to seal the apex properly leaving a gap that the occasional bird gets through. It has made an enormous difference to the comfort level. Andrew |
