“…Insulation boards are produced either by using adhesives or by hot-pressing. In addition to conventional synthetic adhesives, natural binder, e.g., starch, casein, sodium alginate (Palumbo et al, 2015(Palumbo et al, , 2018, gelatine (Ismail et al, 2021) and natural rubber latex (Tangjuank, 2011), as well as inorganic binders, e.g., gypsum (da Rosa et al, 2015), lime (Ismail et al, 2020(Ismail et al, , 2021 and sodium silicate (Bakatovich et al, 2018;Bakatovich and Gaspar, 2019), were studied to produce insulation boards. Since the binding capacity of mineral materials like gypsum and lime is low, high proportions of these binders are necessary to ensure sufficient stability (Ismail et al, 2020).…”
