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 melts. The molten material is spun int…
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 asb...
