Asbestos Siding Insulation

Covering old asbestos shingles with new siding may seem like an option too but it s not easy to do safely.

Asbestos siding insulation.

Exposure to and breathing asbestos fibers can result in lung problems and cancer. You can t drive screws and nails through them without pre drilling. Asbestos paper was used to wrap the exterior of heating ducts and their connection to heating registers. Asbestos shingles are relatively strong but brittle.

Vermiculite loose fill insulation is one of the most common household materials that contains asbestos. All materials containing asbestos must be soaked in water. But asbestos removal isn t as cut and dried as it may seem. Asbestos has been linked to asbestosis and mesothelioma lung diseases caused by breathing asbestos fibers.

Asbestos siding was made by adding asbestos a naturally occurring mineral to portland cement. Asbestos fabric was used to form the vibration damper at the connection between heating ducts and heating furnaces. The resulting product was very durable fire resistant and absorbed paint well. Vermiculite insulation has a pebble like appearance and typically is a grayish brown or silvery gold color.

Let the siding dry then prime and paint with the best exterior latex you can find. Due to its strength and heat resistance it. While not commonly found today asbestos use in building materials has only been partially banned specifically from spray on insulation paper materials and any new uses. Asbestosis irritates and scars the lung tissues while the more dangerous mesothelioma causes a type of cancer that is often fatal.

From 1930 to 1980 asbestos was used in a number of property building. Class i involves the removal of asbestos in thermal system furnaces and duct work insulation. It is made from a natural mineral material that is mined from the earth. See asbestos duct vibration dampeners.

With both classes projects must be completed in an enclosed and regulated area. For a century the naturally occurring fibrous silicate mineral asbestos was a mainstay of the building industry used to create products of all kinds. It is very brittle and has a tendency to crack and break when nailed which can release asbestos fibers into both the air and ground. Asbestos siding is composed of asbestos fibers mixed with portland cement.

Asbestos is a mineral fiber that in the past was used as a flame retardant strengthening agent that provided heat insulation. That cement was then pressed into siding shingles that came in a wide variety of sizes profiles and textures.
