A premium insulation material made from natural volcanic rock, processed into high-quality mineral fibers with a density range of 60–100 kg/m³. Its balanced and stable fiber structure provides excellent sound absorption and thermal resistance, while remaining lightweight and easy to install. With high heat resistance and non-combustible properties, Duorock Rockwool is ideal for ceiling and wall partition applications across various building types.
Made from high-quality materials, long-lasting, and resistant to damage.
Lightweight and dense structure allows for easier and more efficient installation.
Free from harmful substances, safe for skin contact and respiratory health.
Effectively reduces noise with high sound absorption performance (NRC 1.2).
Reduces external heat and helps maintain indoor temperature stability, including in air-conditioned spaces, while maintaining structural stability in humid conditions.
High performance with a more efficient and competitive price point.
1. Lay the roof mesh over the purlins. This wire mesh functions as a support to prevent the Duorock insulation from sagging. Secure it using screws at every purlin intersection point.
2. Install the aluminium foil layer over the roof mesh. Ensure all joints overlap by approximately 10 cm, then seal them using aluminium tape to prevent any air or vapor leakage.
3. Place Duorock insulation over the foil layer, ensuring each board is tightly fitted without gaps. Cut Duorock using a sharp saw according to the spacing between purlins.
4. Once the insulation is properly installed, install the battens or roof framing according to the design plan, then secure them using screws.
5. Install spandek or metal roofing sheets on top of the battens. Use SDS (Self-Drilling Screws) with sufficient length beyond standard requirements to ensure the roofing sheets are firmly and securely fastened.
