Disaster recovery and restoration can be veiled in mystery to the many who have not undertaken specific training. This glossary explains technical terms to assist both report writing and the understanding of those technical terms so often misunderstood.
Definitions
| Acoustic Materials: |
Building materials which absorb sound and noise, such as carpet and acoustic tiles. Education Note: Most sound absorption materials, besides being good sound insulators, are also highly absorbant, and they are capable of retaining unwanted moisture and humidity after a water damage. |
| Acoustic Tile: |
A formed material usually made with cellulosic substances and binders, that are compressed into a tile form. Acoustic tiles take many shapes, from 12"×12"×2" tiles that are stapled or mastic adhered to walls and ceilings, to 2'×2'×2' and 2'×4'×2" tiles for placement into a ceiling grid. |
| Asbestos: |
A family of silicate minerals that are non-conductive to heat and electricity. The minerals have been used extensively in insulating materials, including insulation, acoustic tiles and ceilings. Asbestos is a good insulator, but friable asbestos has been known to cause illness and death. health and Safety Note: damaging asbestos containing materials (ACM) from fire and water, may result in some of the mineral fibres becoming airborne and friable. Mitigation Note: a) Remediation contractors may be required to test fior the presence of ACM. If asbestos is suspected, air movement must be restricted and HEPA filtered negative air equipment must be properly installed. b) Asbestos requires sampling and testing to confirm the material(s) actually contain asnestos. depending on the amout of ACM to be removed, a licensed asbestos abatement company will need to be hired. |
| Hygroscopic Building Materials: |
Building materials which have a natural affinity to hold and retain water and moisture vapour, especially building materials when indoor humidity exceeds 70% for periods of time. Restorative Drying Note: a) Building materials, such as blown acoustic ceilings and acoustic tiles, drywall and wall insulation, which attract, readily absorb, and take up water and moisture vapour. b) Once saturated, hygroscopic building materials will not release their water and moisture vapour as fast as they retained it. c) Hygroscopic building materials when wet or damp, are typically those materials that aid in the distribution of spores.
