Vermiculite is another compound that was very popular a few decades ago for its fire-resistant and insulative properties. We often see the original vermiculite with six or so inches of blown-in cellulose insulation on top. Because the fine asbestos fibres have saturated the attic, we need to remove all added insulation to achieve a clearance. We have substantial experience with safely removing vermiculite from homes and businesses throughout Greater Victoria. If your hazardous assessment has revealed the presence of vermiculite, give us a call to see how quickly and easily we can take care of your problem.
Vermiculite is a mineral which expands when heated, much like popcorn.
Not all vermiculite contains asbestos. Asbestos, also a mineral, was often running through the mining area where vermiculite was found. The best known case was at the largest vermiculite mine in Libby, Montana. The vermiculite was branded Zonolite and sold for over 40 years.
Since vermiculite is typically found in attic insulation, there are a few aspects that need to be factored into the cost of removal. Effective planning on your part can reveal substantial savings.
Time of year (summer vs. winter)
Pitch of roof (how easy is it to move around in your attic?)
Amount and type of materials
Drywall vs. plaster ceilings
Presence of knob and tube wiring (rare, but we're still finding it)
