Disaster Advice Glossary

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 Ceiling: |
A ceiling that has the ability to absorb sound. |
| Acoustic T-Bar Ceiling: |
A ceiling made with metal wire hangers and metal T-bar assembly, and inserts of 2' × 2' or 2' × 4' acoustic ceiling tiles. Acoustic T-bar ceilings are usually found in commercial building and offices. |
| Blown Acoustic Ceilings: |
The adhesive and acoustic material sprayed on to a ceiling, giving the ceiling an even appearance and better sound absorption. Prior to 1980 and as late as 1994, some of the blown acoustic ceilings contained asbestos. |
| 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.
