5. BASIC GROUPS OF MATERIALS WOOD ENGINEERED WOOD TILES GYPSUM/DRYWALL PLASTER/CONCRETE

6. BASIC GROUPS OF MATERIALS WOOD ENGINEERED WOOD Hardwood flooring and millwork will absorb moisture from the air and from a wet slab . Warping and bending will result if the moisture is not removed before installation.

8. Climate Control Drying purposes Desiccant dehumidification can provide warmer drier conditions for: Working personnel

15. HEAT VS. DEHUMIDIFICATION … does not decrease moisture content but does increase the ability of air to hold moisture. … decreases RH but does not change the dewpoint. … makes it difficult to maintain a proper dewpoint spread with heaters only. … may damage coatings and produce uncomfortable work environments. … is very important for moisture movement but … … too much heat may push moisture deeper into the materials. … hot moves to cold and can cause condensation issues . HEAT…

17. HOW DESICCANT DEHUMIDIFICATION WORKS? High volume desiccant dehumidifiers exhaust extremely dry air into the construction areas. The dry air lowers the vapor pressure and dew point of the building air, causing moisture in materials to pass from levels of high pressure to low pressure. Construction materials are dried out and mold is controlled, allowing the project to proceed without moisture delays.
