Did the brand Texas Rockwool insulation ever contain asbestos?
Ldp, Best to get the info from sources who have a history in studying the question in detail. Here’s an excerpt on the subject with some references: Go to NAIMA’s website…you can also go to epa.org….and of course Amerrock.com…Rockwool is made of slag, which is a recycled steel product, and rock, a trap rock mined in Texas…those are the only raw materials in rockwool insulation..we use “coke” which is a recyled material from coal..it is used to make the heat hotter in the manufacturing process, in order to save energy.
