GYPROC products provide high levels of airtightness and moisture protection to a building envelope. Their thermal qualities help protect and extend the life cycle of the building.
To limit the potential for bacteria and mold growth within buildings from water infiltration and condensation.
Part 1: Exterior Liquid Water Management
A point-by-point narrative describes how liquid water from outside the building is addressed; responding to the nature and intensity of wetting based on the project's site and climate, and includes the following leading concerns:
- Site drainage, including the impact of any site irrigation.
- The local water table.
- Building penetrations (especially windows and plumbing/electrical/mechanical penetrations).
- Porous building materials connected to exterior sources of liquid water.
Part 2: Interior Liquid Water Management
A point-by-point narrative describes how liquid water from interior sources is addressed, including these leading concerns:
- Plumbing leaks.
- "Hardpiped" plumbing appliances (appliances such as clothes washers exposed to building water pressure even when not in use).
- Porous building materials connected to interior sources of liquid water.
- New building materials with “builtin” high moisture content or building materials wetted during construction but now on the inside of the building.
Part 3: Condensation Management
A point-by-point narrative describes how condensation is addressed, including these leading concerns:
- High interior relative humidity levels, particularly in susceptible areas like bath and laundry rooms and belowgrade spaces.
- Air leakage which could wet either exposed interior materials or interstitially “hidden” materials.
- Cooler surfaces, such as basement or slabon-grade floors, or closets/cabinets on exterior walls.
- Oversized air conditioning units.
Part 4: Material Selection and Protection
A point-by-point narrative describes how moisture-tolerant materials have been selected and/or moisture-sensitive materials (MSP) are being protected, considering these leading concerns:
- Exposed entryways and glazing.
- Porous cladding materials.
- Finished floors in potentially damp or wet rooms such as basements, bathrooms and kitchens.
- Interior sheathing in damp or wet rooms.
- Sealing and storing of absorptive materials during construction.

PARTS 3 a, 4 c and d:
GYPROC offers a range of moisture resistant gypsum and plasterboards that are ideal for damp and wet environments such as basements, bathrooms and kitchens. Their efficient water repellent properties offer superior protection from moisture damage, providing a system that can be installed on its own or that may provide a suitable base for ceramic tiles. The frequency of inspection and maintenance is reduced, avoiding or completely omitting water damage, surface discoloration, mold and other bacterial issues.
