Question: Which type of drywall is specifically designed for use in areas with high moisture, such as bathrooms and laundry rooms, due to its specialized paperless or treated core?
Answer options:
- Regular gypsum board
- Type X fire-rated drywall ✅ Moisture and mould resistant gypsum board
- Sound-dampening drywall
Correct answer: Moisture and mould resistant gypsum board
Explanation: Moisture and mould resistant gypsum board is specifically manufactured with additives in its core or a fibreglass mat facing to retard moisture absorption and prevent mould growth, making it ideal for high-humidity environments. Regular gypsum board is not suitable, Type X is for fire resistance, and sound-dampening drywall focuses on acoustic properties.
