The term 'glazing' refers to the glass component of a building's facade or internal surfaces.

Historically, the external windows of buildings were generally single glazed, consisting of just one layer of glass, however, multi-layered glazing system were developed such as double glazing and triple glazing.

Single glazing comprises off one layer of glass, bedded into the window frame. Single glazing is usually fixed with linseed oil putty and secured with glazing nails into the frame. Glazing beads can further secure the glass and is usually screwed and glued to the frame. If the window frame is timber it must be painted to avoid water ingress.

U-values (sometimes referred to as heat transfer coefficients or thermal transmittances) is used to measure how effective elements of a building’s fabric are as insulators. That is, how effective they are at preventing heat from transmitting between the inside and the outside of a building. Typically, the U-value of single glazing is around 4.8 to 5.8 W/m²K, whilst double glazing is around 1.2 to 3.7 W/m²K. NB Triple can achieve a U-value below 1 W/m²K.

Thermal performance is affected by the quality of the installation, the inclusion of thermal breaks in the frame, suitable weather seals, and the type of glass used. Low-e glass has a coating added to o its surfaces to reduce its emissivity so that it reflects, rather than absorbs, a higher proportion of long-wave infra-red radiation.

The sound reduction achieved by single glazing (6 mm thick) is typically around 27 dB, whilst double glazing (100 mm air space) is around 42 dB.
