Experience superior ROCKWOOL Comfortboard® in exterior-insulated stucco systems: safety, performance, and sustainability combined.
ROCKWOOL Comfortboard enhances stucco-clad building envelopes with fire resistance, moisture management, and energy efficiency. Compatible with one- and three-coat stucco assemblies, it streamlines design for new builds and retrofits.
Comfortboard's noncombustible composition ensures code compliance, including NFPA 285 and 1-hour fire-rated assemblies. Its vapor-permeable properties boost moisture resistance.
Versatile beyond stucco, Comfortboard excels in below-grade and sloped roofing applications. It minimizes thermal bridging, withstands UV exposure, and maintains performance through multiple recycling cycles.
- Fire-resistant: Noncombustible and code-compliant, with available NFPA 285 and 1-hour fire-rated assemblies for one-coat stucco systems
- Moisture-resistant: Vapor-permeable and quick-drying, enhancing the wall assembly's drying potential
- Durable: High dimensional stability and compressive strength to meet specific structural requirements
- Versatile: Suitable for both one- and three-coat insulated stucco assemblies, new builds or retrofits, and various other applications including below-grade, under concrete slab, floor-ceiling assemblies, and sloped roofing
- Energy-efficient: Minimizes thermal bridging and reduces heat loss, improving indoor comfort and energy savings
- Adaptable: UV-stable to withstand project delays and compatible with dark finishes
- Sustainable: Made from natural, recyclable materials that maintain performance through multiple lifecycles
