My wife and I are doing some reno's in our house. It's a 1.5 storey, with the upper floor being added to the house sometime after WW2 (House built in 1918).
We're mainly tearing out the ugly tile ceiling and imitation wood paneling, adding insulation, new drywall where is needed, and some lighting.
After ripping off everything, we're down to the old drywall. I went in the crawlspace behing this drywall to see how everything looked. In there is lots of pink insulation, and also bags of insulation called:
Red Top Insulating Wool blanket
It is made by Canadian Gypsum Company, which these days is part of US Gypsum Company.
Anyone know if this stuff contains asbestos or other harmful materials? I called USGC's safety line but have not heard back yet.
This site lists "Red Top products" on their list of asbestos containing products but not the insulating wool specifically.
It looks like they also made a product labelled "RED TOP INSULATION BLANKET MINERAL WOOL US GYPSUM COMPANY" that apparently was an asbestos product. I would play it safe until you can find out for sure.
check out Pro Lab in Forida http://www.reliablelab.com/ While I do not use them for my testing they do have a pretty good price structure for homeowners and results of the test should be reliable enough for your needs. This typs of test is not very expensive. You pre-purchase a sampling kit from them. Place some of the product in the bag they send you and mail it out. In a few days, you will have your answer. But like LaMarlowe said play it safe and do not do anything with it until you know for sure.
Great thread ... very useful info from the posters so far.
I just wanted to point out that ReliableLab.com is a site for inspectors. If you're a home owner like me, you will want to go to the following site:
You can order the asbestos sample kit from this site.
FYI, Prolab and Reliable lab is the same company. Although both not very good, they should be able to provide the necessary information for the average homeowner.
Any lab that provides information on the results other then what was found goes beyond proper protocol. A proper lab should only provide the results of what was sampled, not tell you the conclusion if you have an issue or not. Its up to the person who takes the sample to determine this or not.
Just to follow-up on my earlier post, my results indicated that the insulation in my attic (Red Top Insulating Wool Blanket by the Canadian Gypsum Company) did not contain asbestos (e.g. Asbestos: none detected ... 95% mineral wool and 5% binding agents).
I was very happy with the service of Pro Lab. Highly recommended.
Thats good news for you and your family. Glad your asbestos free!
