AI Technical Summary
Existing roofing systems for flat and flat inclined roofs face issues with adhesives dispersing into insulation layers, reducing insulation and damping characteristics, increasing costs, and compromising fire resistance, while formaldehyde-based binders are harmful and costly, and formaldehyde-free alternatives lack durability and mechanical strength.
A roofing system using insulation elements made of mineral fibers with a binder comprising oxidized lignins, cross-linkers, and plasticizers, achieving a bulk density of 70 to 250 kg/m³, which are formaldehyde-free and provide high mechanical stability, low binder content, and improved aging resistance.
The system maintains excellent thermal and acoustic insulation, mechanical strength, and fire resistance over time, reducing adhesive dispersion and binder costs, while being environmentally friendly and safe to handle.
