ComfortAside from its economic and ecological aspects, another important goal of building with glass is the tangible improvements in the living and working environments.
EcologyEvery litre of fuel oil or cubic metre of natural gas that can be saved through using advanced glazing reduces CO2 emissions and benefits the environment.
EmissivityAccording to EN 12898, emissivity is the ratio of the energy emitted by a given surface at a given temperature to that of a perfect emitter (i.e. a black body with normal and corrected emissivity of 1,0) at the same temperature.
Our product: ClimaGuard®GUARDIAN provides a broad range of state-of-the-art thermal insulation layers normally applied to ExtraClear® float glass, which enable the realisation of a range of modern thermal insulation glasses by our customers.
Heat lossHeat loss is influenced by three mechanisms: radiation, conduction and convection.
U value - heat transmission coefficientThis value characterises the heat loss through a component.

Aside from its economic and ecological aspects, another important goal of building with glass is the tangible improvements in the living and working environments. Tinted float glass installed in insulated glass (See Solar Control Comfort Chapter) increases the glazing’s room-side surface temperature, thus minimising unpleasant air flows considerably in areas where glazing is present.
State-of-the-art thermal insulating glass increases this temperature to a near-room temperature levels and significantly improves the comfort level of a home. The decisive factor in comfort is the temperature difference between ambient air and the adjacent wall and window surfaces. Most people find a room to be particularly comfortable when the temperature differences between wall (glass) and room air is no higher than 5 °C and between foot and head height not higher than 3 °C.
The diagram above shows the range where ambient air feels most comfortable. Humidity should always be viewed as dependent on room temperature. When the air temperature is cooler, the humidity should be higher for the space to feel comfortable. Where the room temperature is higher, the humidity should be lower.
