Achieved through the reduction of solar heat gain without the need for significant additional reflectivity, EnviroTone also reduces both UV penetration and glare to the inside of the building. Manufactured by adding different chemicals and metal oxides to the batch during the float glass manufacturing process, the EnviroTone range of toned glass reduces the solar heat gain by absorbing solar energy within the body of the glass. Different colours absorb solar energy to different levels; the darker the glass, the more heat that is absorbed. As such, it’s often the case that toned glass products have to be heat treated (either toughening or heat strengthening) to avoid breakage through thermal stress.
