A recently granted patent (Publication Number: US11919283B2) discloses a method for providing thermal and/or acoustic insulation to a structure using a substrate comprising fibers blended with a binder composition. The binder composition includes at least one hydrocolloid derived from animal sources, along with phenol-containing compounds and enzymes such as transglutaminase. The method involves applying the substrate to the structure, blending it with the binder composition, allowing curing of the binder, and can be used on various building components like walls, ceilings, and roofs.
Furthermore, the patent claims specify that the substrate does not contain mineral wool but may include mineral fibers and particulate materials like aerogel or fire retardants. The curing process of the binder composition occurs at specific temperature ranges, and the method can involve or exclude crosslinking of the binder. The resulting insulated structure, obtained through this method, can have a loss on ignition (LOI) within a defined range, ensuring the effectiveness of the insulation. The use of formaldehyde-free binder compositions, along with animal-derived hydrocolloids like gelatine, collagen, or hydrolyzed gelatine, adds to the environmentally friendly and sustainable aspects of the insulation method. Overall, the patented method offers a novel approach to enhancing the thermal and acoustic properties of structures while incorporating eco-friendly materials and efficient application techniques.
