Asbestos?

[Christopher Currins]

I know the only way to be sure is to test, but does anyone have information regarding Johns Manville "Spinusaltion" containing asbestos?

Since it is a mineral fiber, first produced in the late 50's, there's a good chance that it contains asbestos.

This is the first time I have heard of asbestos being found in a batt style mineral fiber insulation insulation. Have you ever had any tested and verified for asbestos?

Quite right - I didn't really look that close.

I remember the brand name (Spinsulation) from a conversation years ago. The brand name was trademarked from (roughly) 1962 to 1985, and the original product was a mineral based fiber, which was told to have contained traces of asbestos.

The product was discontinued (to the best of my knowledge) shortly after ACM's were prohibited in residential construction.

I would be very curious to know if this insulation is the same stuff.

I've tried to research and the best I can come up with is here. It doesn't include fiberglass, but doesn't say it's excluded either. I'm curious if the paper face may contain it.

Products from the Johns Manville name included asbestos paper, block insulation, cement board, cements, cloth, electrical products, gaskets, felt, floor tile, packing seals, pipe covering, piping, roofing products, siding and wallboard. The company also supplied the raw fibers.

Asbestos paper was used as pipe wrap.

Guess what? Johns-Manville manufactures fiberglass!!!! I worked at their Willows, Ca. fiberglass manufacturing plant back in 1980.

Copper pipes were not used mainly in homes until the mid 60's. How old is the home? Appears to be fiberglass insulation. Yep.
