Definitions

• the present invention concerns the covering elements for buildings and in particular it concerns a new covering with refracting and reflecting upper surface, suited to be used for buildings in general.
• coverings for buildings like coverings consisting of tiles or bent tiles made of burnt clay or cement, coverings consisting of asbestos cement sheets, plate, insulating and waterproof elastomeric sheaths, etc.
• the known sheaths being usually made of dark or black materials, however, are particularly subject to deterioration because of the high absorption of sun rays that is typical of black bodies, even if they are protected by an upper layer of paint or granulated material.
• Sheaths are generally covered with silver or chrome paints that reflect at least partially the incident sun rays.
• the subject of the present patent is a new covering with refracting and reflecting upper surface, suited to be used for buildings in general.
• the main object of the present invention is to carry out a new covering for buildings, whose external surface has a high coefficient of reflection of incident light in order to reduce the absorption of sun radiation and thus to limit the transmission of heat through said coverings.
• Another object of the present invention is to obtain a covering that can be applied to any type of material commonly used for making covering elements for buildings, like tiles and bent tiles, asbestos cement sheets, waterproofing sheaths, etc.
• the new covering comprises, like the known coverings, a plurality of elements like for example:
• Each one of said components of the new covering comprises, on part or preferably on the whole of its upper surface, at least one layer of spheres or microspheres, made of plastic and/or glass and/or ceramic, suited to reflect the light that is incident on them, and wherein said spheres and/or microspheres are made adhere to said elements through the application of paints and/or binders and/or bonding agents and/or other products suitable for this purpose.
• the process for making the new covering comprises the following steps:
• Said spheres or microspheres are constituted by pieces of glass or ceramic and, in particular in the case of said microspheres, have typical dimensions in the order of tenths of a millimetre, or even smaller.
• spheres or microspheres made of plastic material may be used.
• spheres or microspheres may be used, that is, spheres or microspheres having a silvery hemisphere, and therefore suited to lend a chromed hue to the surface of said support, thus further enhancing the reflecting effect of the spheres.
• Said elements for making coverings, treated as described above, can then be installed and their external surface, partially or completely covered with said spheres or microspheres, is characterized by a high coefficient of reflection of incident light.
• the process includes the following steps:
• Said tiles, bent tiles and/or said sheets substantially comprise at least one layer of paint, for example silver or chrome paint, and/or at least one layer of bonding agent and/or binder, suited to ensure the adhesion of at least one layer of said spheres or microspheres.
• paint for example silver or chrome paint
• bonding agent and/or binder suited to ensure the adhesion of at least one layer of said spheres or microspheres.
• Each one of the elements that make up the new covering thus features a reflecting surface, which considerably limits the transmission of incident sun radiation through the covering itself, and therefore minimizes the transmission of heat.
• Said process can be applied also to insulating and waterproofing sheaths and comprises the same steps described above, that is, the spreading of a binder and/or bonding agent and/or paint, transparent or coloured, on the upper surface of the sheath and the successive application of said spheres or microspheres.
• said spheres or microspheres can be applied to other types of support, like for example sheets or layers of paper and/or plastic material, suited to be successively associated with said elements making up the covering and in particular with said waterproofing sheaths.
• Said spheres or microspheres can be sprayed onto the surface to be treated together with said paint, in a single step.
• said spheres or microspheres can be applied after a transparent binder and/or bonding agent.
