When it comes to controlling moisture and resulting mould growth, it can be hard to separate fact from fiction. But the bottom line is this: mould spores are everywhere, and they can grow on virtually any surface where moisture is present. Consequently, controlling mould growth begins with moisture control through best building practices.

Adding the right protection in the right places is a critical aspect of the equation. And that’s where CGC Sheetrock^® Brand gypsum panels with Mold Tough^® technology really make their mark. These panels come from a comprehensive product line of moisture- and mould-resistant solutions that meet ASTM C1396 specifications. This ensures that customers have the highest-performing materials in the fight against mould and moisture.

Manufactured with a proprietary blend of ingredients, Mold Tough protects the wallboard from moisture and mould that adopts the familiar appearance of the green board. Encased in moisture- and mould-resistant material, it’s made of 100 per cent recycled green face and brown back papers. The face paper is folded around the long edges to reinforce and protect the core and the ends are cut square and even.

Control Moisture, Control Mould

Even if your drywall contains moisture- and mould-resistant properties, it can still be at risk for mould growth if not for careful design, proper construction and thorough maintenance. These factors are meant to manage moisture, which is the only variable that can be controlled within the construction environment. The risk for mould growth can be elevated by:

• Product storage and installation conditions
• Poor execution of water control
• Energy-efficient buildings without moisture-management design.
• Snow and rain exposure during the construction phase
• Inadequate drying of concrete, plaster and paint as a building is completed
• Roof and pipe leaks
• Excess water penetration of the façade

Moisture is critical because mould is unable to develop and grow without it. When the risk of moisture exposure is present, be sure to choose products and systems that offer added resistance in conjunction with sound design and construction practices. Limiting moisture during the construction phase allows mould-resistant products to act as extra protection against mould growth when incidental moisture (condensation, steam or dampness) is present.
