Browse Forums DIY, Home Maintenance & Repair 1 Sep 05, 2011 3:46 pm I know the true answer is that to be sure if something has asbestos, the only way to tell for sure is to have it tested. That being said, if your adult kid was going to be putting in R49 blown in cellulose into their attic, and these pictures were in their attic, would you have it tested or say go for it? I don't have much DIY home expertise at all. But, I think I'm looking at a bit of fiberglass batts with a small amount of cellulose blown in insulation on top of it. The only thing that concerns me is the appearance of a bit of gravel'ish substance on top. I know vermiculite often contains asbestos. But, it makes more sense to me that these bits are from shingles, because for some reason there's shingles up there too. I'm assuming the roof's wood may have been replaced along with shingles, and perhaps that got bits of shingle all over the place? (Click on any photo to enlarge it!)

We have learnt that the hard way, even with sheet materials. Our policy now is that if we don't know then we assume it is asbestos. The alternative as you rightly suggest is to have it tested and that is not all that expensive - I think probably under $100 which is a lot cheaper than getting an asbestos removalist involved! Builders are people too.... Re: Any (reasonable) chance this attic insulation has asbest 3Sep 17, 2011 10:00 am I too strongly suggest you have the material tested. I dont know where you are but in SA I had some eaves lining material tested for free. Arfur Seems good to me. I've been told $4-5k/sqm is reasonable in Perth. 2 11131 What you are looking at is fibrous plaster, true gypsum, it is cast on horizontal beds with fibers included to give strength. I has no Asbestos in it. Houses before 1985… 2 7113 4 1825 |
