Commercially available thermal barrier panels in the construction and building industry are typically made of glass fiber reinforced refractory materials (more commonly, magnesia and gypsum) or fiber cement boards. With high costs associated with these boards (in particular magnesia and fiber cement) along with their susceptibility to hydrolysis (water activity), there is a huge demand and need for alternate materials that can serve the purpose of fire barrier, have the desired levels of mechanical strength, moisture resistance, and acoustic performance, that are yet economical. This is the basis of this technology where the cradle-to-cradle concept is emphasised.
Natural fibers like oil palm fibers (OPF) are used in the development of these boards. OPFs or OPF mats are pre-treated with non-halogenated fire retardants before impregnating them with an organic and/or organic/inorganic binder to make boards. These boards upon exposure to direct flame or intense radiation (according to a standard ISO 834 fire curve) provides substantial protection. Based on different tests that were performed in the laboratory, the product complies with BS476 Part 4 and Part 22 along with other standards associated with mechanical properties. Apart from the waste management advantage, other competitive advantages of this technology include water resistance and sound absorption. As many developers are adopting the drywall systems based on boards instead of conventional brick walls in recent construction projects due to their simplicity and sustainability, there is a huge potential for these novel boards.
