Shingle type siding

[gjoubert (Gideon J. Joubert)]

I have looked at a house with siding that seem to look like shingles but is actually panels that are 43 and 1/4 inch long by 14 inches wide and about 1/2 inch thick. It seem to be tongue and groove. The finish on it has granules like shingle but was done in a specific pattern with different colors. Where it has deteriorated it turns into a dark brown powder like substance if you break it down. Does anyone know what the product consist of. Is there a possibility that there could be asbestos in the product? I have attached 4 pictures.

YES! “Possible ACM”.

Does Old Asphalt Building Siding Contain Asbestos

I was just wondering if the Brick looking asphalt siding ever contained any asbestos or hazardous material. Your opinion would be greatly appreciated.
I need to remove some of this product but will use a knife to cut it into pieces and bag it appropriately. Also i am having a room demo that is 20x38 and the drywall joint compound is suspected to have chrysotile asbestos contained. I have taken appropriate measures and have sealed of the area with 6mil poly and taped the joints. Should this upon removal be sprayed with water or are the asbestos crystals encapsulated in joint compound. Have you come across this situation. Thank-You. D.T., Canada

I have asphalt faux brick Finnish shingles on the back of my house how can I tell if they are asbestos? The house was built in 1920 and the addition was later on. The owner said they were asbestos but with the seizures his memory is not there.
Reply: Maybe.

A competent onsite inspection by an expert might confirm the age and type of this particular asphalt-siding product, and also, based on the probable building age, it is certainly possible that other asbestos-containing materials are present. That said, here are some things to consider:
In general I think you are referring to an asphalt product that is made essentially of the same material as asphalt roof shingles, though some versions applied bituminous and asphalt and mineral granules to a hardboard base rather than a paper (“organic”) base.
Some asphalt roof shingle products, and therefore quite possibly some asphalt siding products, did indeed contain asbestos fibers in their substrate or coating. Roof shingles, even if the material contained asbestos (which it might) are rarely the only nor even the principal source of problem-levels of asbestos fibers in a building and I suspect the same is true of asphalt-based building siding. That’s because the asbestos fibers are encapsulated in asphalt or similar non-friable bases.
There might be a concern if building demolition is underway and the removal of old siding created dust - especially if power tools such as power saws or grinders were used.
Watch out: if that’s going on with your building it would be prudent to use appropriate dust control measures and to minimize the break-up of the material, and especially, to avoid using power saws. And there may be provincial or local municipal regulations that govern the demolition and removal of these materials.
Kent some old asphalt roofing and siding materials contained asbestos but to know for sure you’d need to send a small sample to a certified asbestos testing lab. If you can send me some photos I can comment further.

search insulbrick siding
numerous colors/styles were produced by different mfr from the 1930s-60s
it was the cheap siding of choice to cover aged/damaged wood siding long before aluminum & vinyl ever made the scene

if you know what celotex was
image it stamped with a brick pattern, coated in asphalt & colored granules added for the cherry on top
