The majority of structures built before 1985 will contain products that have substantial amounts of asbestos.
Asbestos can be “friable” (easily crushed into dust with the fingers) and “non friable” (difficult to crumble into dust). They can be found on:
- Pipe and boiler insulation, ductwork, drywall and joint compound, plaster
- Sprayed on fireproofing on building beams, columns… or on acoustic ceiling
- Vinyl floor tiles, vinyl sheeting and mastic, glues, roof shingles, tar
- Transite panels and siding, lab countertop
- Windows caulking
- In attic insulation (Vermiculite)
