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.
Definition
| Absorbency: |
The moisture measurement difference between a dry porous material and a saturated material is a weight neasurement of the material's absorbency. Education Note: The ability of a porous building material, like drywall and some insulation, to absorb water, and very high humidity, rapidly. |
| Absorption: |
A process whereby a porous material extracts one or more substances present in an atmosphere or a mixture of gases and liquids, accompanied by the material's temporary physical and/or chemical change into another material. Education Note: Absorption in water damage building materials is the temporary entrapment of moisture into porous and semi-porous building materials, such as carpets, pad, drywall, and cellulosic insulation. See Absorb, Absorbency, Absorption |
| Adsorbent: |
The incorporation of a liquid or energy absorbed into another substance. Absorbent of a substance can be a permanent change to the building material, such as sewage contamination, fire, odour or pesticide exposure. Education Note: For example, the rate of absorbency of drywall to absorb a substance or a vapour will, most likely, cause permanent damage to the drywall material. Note: 'Absorbent' means to melecularly bond together. See Absorbent, Absorption |
| Flashing: |
Referring to a painted surface, flashing is the uneven gloss on the wall, particularly when viewed at a low angle. Education Note: High and low (sheen) spots (flashing), can be observed as small or large discolored areas on a flat wall surface. Flashing is sometimes caused by the premature painting over a wall that has not fully dried after a water damage, or a wall that has differences in its substrate absorbency. |
