Does Hardboard Siding Contain Asbestos

Although homes built after the 1980s are generally safe some newer builds may also have asbestos lurking in the siding.

Does hardboard siding contain asbestos.

Indeed some gypsum based drywall products did contain asbestos into the 1980 s. The siding may also contain asbestos if it is old with a wood grain texture to resemble cedar. Some gypsum board and plaster board products indeed contain asbestos as does some joint compound. Asbestos cement roof ing is described just below and cement wallboard and cement siding containing asbestos are described later in this document.

However fixer uppers and older homes with their original siding may still contain this dangerous material. Testing your siding for asbestos if your siding fits either of these descriptions you should consider having it tested. Most homes built after the 1980s no longer use siding that contains asbestos because of its obvious health risks. I was just wondering if the brick looking asphalt siding ever contained any asbestos or hazardous material.

Before 1978 in the u s. The common reinforcing fiber used was asbestos. These materials are known as fiber cement siding and they contain no asbestos. Manufacturers use asbestos in fiber cement siding although some of the earlier versions of fiber cement siding did indeed have some asbestos particles blended in fiber cement was actually designed to replace the asbestos siding products to create a safer environment for the installers and the home s residents.

These shingles are generally 12 by 24 inches and the bottom tends to have a wave like pattern though that is not always the case. Some manufacturers use the term fiber reinforced cement for these products. All of these products use some sort of fiber along with cement. There is no legal requirement to do so nor is there significant real estate benefit.

I have not however tested nor seen test results specifically for exterior wall sheathing using that material. As we note at hdf high density fiberboard synonyms or equal product names besides masonite include hernit karlit quartrboard treetex torex and pressboard. Your opinion would be greatly appreciated. Cement asbestos siding tiles do not need to be removed simply because they contain asbestos.

I need to remove some of this product but will use a knife to cut it into pieces and bag it appropriately. Cementitious siding installed after 1973 is very unlikely to contain asbestos. Siding materials that use fibers and aggregate other than asbestos are properly called fiber cement building siding products.
