Low Embodied Energy Advanced (Novel) Insulation Materials and Insulating Masonry Components for Energy Efficient Buildings.

A review of the embodied energy values of the various building materials shows that the embodied energy of the most widely used insulation materials in construction applications is characterised by very high values. This mainly results either from the energy intensive conditions applied for the manufacturing of the mineral based insulation materials or from the high embodied energies of the oil-based raw materials used for the production of the organic based ones. Moreover, conventional insulating materials can suffer from various disadvantages including not stable thermal and acoustic performance overtime, combustibility, shrinkage and settling, and pollution of the indoor building environment. In this frame the objective of the project was the development of a new generation of inorganic insulation materials and building insulation masonry components, that have 70 – 90% lower embodied energy, 25 - 30% lower unit cost, than the synthetic organic and mineral based ones, like EPS, XPS, Stone and Glass Wool, and at the same time they do not present their technical, health and/or environmental drawbacks. New formulations and products are called “3I” materials, since they are Inorganic, Insulating and Incombustible. This objective was achieved through the development of innovative technological routes for the production of the 3I materials, combining: a) use of appropriate inert, natural alumino-silicate raw materials, originating from “zero-embodied energy” wastes of industrial mineral exploitation (i.e. perlite, bentonite, amorphous silica and other volcanic minerals) and other industrial wastes and by-products; b) application of novel low energy consuming synthesis processes based on inorganic polymerisation and thermal expansion that take advantage of the unique and favourable chemical and mineralogical composition of the above wastes; and c) addition of appropriate mineral by-products (fluxes) that easily react with the above wastes through highly exothermic reactions forming inert stable structures. The assessment of the environmental sustainability of each one of the new insulation components was performed with life cycle assessment studies.
