BS EN 1096-5 is part five of a multi-series of European standards on glass in building — coated glass which covers test method and classification for the self-cleaning performances of coated glass surfaces.
BS EN 1096-5 defines a test method to establish the self-cleaning performances for coatings on glass which utilize sun, rain or a combination of sun and rain to enhance the cleanliness of the glass.
BS EN 1096-5 applies to class A coated glass as defined in EN 1096-1 and EN 1096-2 for use in outdoor building applications. The test is designed to be applicable for coatings on glass which use hydrophilic or photocatalytic active functionalities to enhance the cleanliness of the glass.
BS EN 1096-5 on coated glass is useful for:
Coated glass is an industrial glass product onto which metal oxides are sprayed in the form of thin coatings (0.01 µm to 0.8 µm). The coating is thus composed of a stack of sub-coatings of different types and thicknesses. It modifies the behavior of the glass with respect to solar radiation, in the visible and infrared domains. On distinguishes between pyrolitic and magnetron coatings. The latter can only be used on the internal surface of insulating glazing.
A photocatalyst coating is a coating that contains photocatalysts as ingredients. To explain it another way, it is very similar to Photosynthesis where light energy is transformed to a chemical energy.
BS EN 1096-5 walks us through the self-cleaning performances for coatings on glass that utilize sun, rain or a combination of sun and rain to enhance the cleanliness of the glass. Self-cleaning glass can save you time, work and the cost of cleaning supplies. It is low maintenance, but only if it receives sunshine and rain on a regular basis. Owing to the above reasons BS EN 1096-5 can help you reduce costs and increase efficiency.
