Knauf Aquapanel Rooftop System

The Knauf Aquapanel Rooftop Board System is a specialised, high-performance solution designed to provide a durable, moisture-resistant substrate for rooftop applications exposed to wet and humid conditions. Central to this system is the Knauf Aquapanel Rooftop board, engineered to withstand the harsh environmental challenges of rooftop installations while ensuring long-term structural integrity and protection.

The Aquapanel Rooftop board is manufactured from a robust cement-based composition reinforced with alkali-resistant glass fibre mesh, delivering exceptional resistance to water ingress, mould, mildew, and weathering effects such as wind, rain, and temperature fluctuations. This makes it particularly suitable for use as a substrate beneath roofing membranes, green roofs, and other rooftop finishes where moisture exposure is frequent and prolonged. Designed for ease of installation, the board is lightweight yet strong, facilitating handling and reducing labour time without compromising on durability. Its flat, stable surface provides an ideal base for secure adhesion of roofing membranes and other protective layers, ensuring a reliable and long-lasting rooftop system.

The Knauf Aquapanel Rooftop Board System complies with stringent building regulations and standards for moisture resistance, fire safety, and environmental performance, offering peace of mind for builders, designers, and occupants alike.

Key Characteristics

• The Aquapanel Rooftop board is one of the lightest cement boards available for roof applications, typically 6mm thick, facilitating easier handling and installation.
• The board is completely waterproof, making it ideal for rooftop environments exposed to rain, moisture, and humidity.
• Designed to withstand mechanical stresses, the board is strong, durable, and impact-resistant, suitable for accessible roofs and areas subject to foot traffic.
• The board offers excellent compressive strength, ensuring structural stability and support under load.
• The cement board is reinforced with a two-dimensional grid of alkali-resistant glass fibre layers arranged longitudinally and transversely, enhancing strength and dimensional stability.
• The board maintains its integrity and performance despite exposure to wind, rain, temperature fluctuations, and UV radiation.
• Classified as A1 reaction to fire according to EN 13501-1:2019, providing excellent fire safety performance.
• Meets harmonised technical specifications and building regulations, including EN 12467 for mechanical resistance and durability.
• Suitable for use as a substrate beneath roofing membranes, green roofs, and other rooftop finishes, providing a reliable base for waterproofing and insulation layers.
