Abstract: A masonry system having a primary masonry unit with final coating and thermal and acoustic insulation, with several derivations. The masonry system guarantees the construction of a wall providing final finishing and thermal and acoustic insulation simultaneously. The system is based on a primary masonry unit having a coating layer in its outer face and an insulation layer which, depending on the version adopted, can be situated in the inner face thereof or in the outer face, covered by the final finishing layer in the latter case. The primary units present a tongue and groove fitting system which allows an easy and quick fitting, allowing the placement of these same units by wet or dry process. The masonry system further foresees secondary units and metallic reinforcements, to prevent phenomena of cracks and fissures and to improve the anti-seismic behavior of the wall.

Abstract: A system for improving indoor air quality for shared and confined spaces with people. This allows an improvement in surrounding air quality in indoor spaces and interaction situations with (i) groups of people among themselves (inter-person transmission), (ii) between people and the above-mentioned indoor spaces (confined spaces, buildings and/or airborne and/or overland and/or seaborne passenger transportation systems and/or confined patient transportation systems such as pods/incubators and others similar thereto), and also (iii) for interaction between people and invasive and non-invasive mechanical ventilation systems. The system proposes the use of a system based on fluid mechanics and UV wavelengths for inactivating viruses and bacteria.
