Preparation
Diagnosis
- How, exactly, can you identify whether your attic insulation is asbestos? Let's look at the particulars of loose-fill insulation that may contain asbestos.
Safety
- The main source of asbestos danger concerns vermiculite attic insulation, but not all brands or all sources of vermiculate pose a hazard. There is nothing inherently bad about vermiculite, which is a pellet-like mineral that expands at high temperatures and which is often used for gardening as an amendment that loosens soil and improves its ability to transmit water.
Other uses
- Vermiculite is also used for insulation, in particular, the vermiculite that was mined by the Libby company in Montana for about 70 years, under the brand name Zonolite.
Properties
- Although Zonolite is a mineral, it is lightweight, because during the production process it is subjected to high heat that causes the particles to puff up. If so, it is probably cellulose insulation. Cellulose has a high recycled paper content, no minerals. Close examination will show that this puffy gray material does not contain earth minerals at all, but will look like shredded gray paper. …
Types
- Another mineral-based loose fill insulation is rock wool, which frequently appears as bundles of fibers with a soft, cottony appearance. Rock wool is white, off-white or brownish-white. Rock wool is a manufactured product, made by melting basaltic rock and dolomite and adding binders. The raw material is heated to 2,750 degrees Fahrenheit until it ...
Risks
- If your loose-fill insulation fits the visual cues for vermiculite insulation, you can check to see if it is the asbestos-carrying Zonolite type by purchasing a DIY asbestos testing kit or seeking a commercial firm who can test for asbestos. DIY kits are usually available for less than $50. If you discover that you do have insulation containing asbestos, you are well advised to seek an abate…
