Description of project idea incl. theme and activities

The principal objective of the project is to obtain a thermal envelope for buildings by injecting inorganic thermal and acoustic insulation (TAI) material between the skin of the outer and inner walls that form the thermal-acoustic insulation cavity. This gives an energy saving of 20% compared with traditional techniques, using a new and innovative product that is applied in a continuous process thus avoiding any heat bridging. This product is not based on petroleum (as are the products currently on the market). It is inorganic, recycled materials are used to produce it, it does not damage the environment, is non-combustible and of course thermally and acoustically efficient. And of particular importance for building at the present time, the initial inorganic raw materials are the cheapest on the market, which allows us to offer a price that is highly competitive and efficient for its introduction. Inorganic thermal insulation can achieve a saving of 20% on the average house’s energy consumption, so it is one of the most important ways of reducing overall CO2 emissions at a global level. In addition, thermal insulation accounts for 0.1% of the total cost of building a house and is the only material whose cost is recovered solely by the energy saving it permits. Its great efficiency as both thermal and acoustic insulation is due to its structure, which is similar to an inorganic sponge containing pockets of gas and air, and this enhances its insulating properties. It should also be emphasised that it is easy to apply, reducing labour costs, so its low cost makes it very competitive. For years attempts have been made to develop an inorganic foam that is not based on petroleum as an alternative to the products currently in use. This inorganic foam would have to contain pockets of air/gas to give it thermal and also acoustic insulation properties. Of course, as already stated, it would have to be inorganic, and thus environmentally friendly and not only flameproof but also non-combustible. Nueva Tecnología Rehabilitación y Reformas S.L, has researched this process by trying to generate an inorganic foam for thermal and acoustic insulation in order to produce a foam that would have greater capacity as a pore filler, increased thixotropy and greater adhesion when applied, which could be applied at up to double the required thickness, and above all, so that the inorganic foam would form well, not shrink and the gas/air would remain trapped inside it. In addition it is applied using a continuous process that requires practically no labour. Thanks to the great innovation achieved in obtaining an inorganic foam, which no-one has previously achieved with a minimum thickness of application of 5 cm more than satisfactory results are achieved compared with existing insulation materials, and without forgetting that it does not depend on fossil fuels, since none of its compounds derives from them. Its composition includes recycled raw materials of industrial by-products. All the objectives have been met and the results obtained are very good from the technical, environmental and economic point of view.
