AI Technical Summary
The adhesives used in existing roofing systems contain expensive and harmful substances, which reduces insulation and damping properties. Furthermore, formaldehyde-free adhesives are prone to aging under load and cannot meet long-term use requirements.
Mineral fiber insulating elements, formed using a water-based binder containing oxidized lignin, crosslinking agents, and plasticizers, have a bulk density between 70 kg/m³ and 250 kg/m³, providing excellent mechanical stability and anti-aging properties, while avoiding the use of expensive and harmful materials.
It achieves mechanical stability and low strength loss for long-term use in roofing systems, while reducing adhesive usage, maintaining insulation and damping properties, and meeting the fire resistance requirements of European standards.
