Types of Window Glazing
Types of Window Glazing
There is a number of window glazing options available. London Glaziers understand people often find it overwhelming when selecting window glazing because they are unaware about how each type differs. After a frame is chosen for the glass, you choose the type of glazing you want which will improve your property’s energy efficiency.
Factors which Affect Glazing Options
Customers should consider a number of factors before they select their type of glazing
– Climate
– Building design
– Location
– Window orientation
– Thermal properties of glass
– Style of building design
Types of Window Glazing
– Gas Fills
Some manufacturers fill the space between each pane with inert gas which is commonly krypton or argon. They do this to improve the thermal performance of windows so that it has a higher resistance to heat flow than air.
– Heat-absorbing Tints
Heat-absorbing window glazing can change the colour of the glass through special tints. Tinted glass reduces the solar heat gain coefficient, visible transmittance and glare because it absorbs a large amount of any incoming solar radiation. However, the window’s U-factor doesn’t decrease because some heat continues to pass through the window through re-radiation and conduction.
– Insulated
A window must have two or more panes of glass for insulated window glazing. The glass panes are spaced apart and hermetically sealed which leaves an insulated air space. As a result, the U-factor is lowered but it also reduces the solar heat gain coefficient.
– Low-emissivity coatings
The heat transfer through windows can be controlled with low-emissivity coatings on glazing. Low-emissivity glass often costs more than regular windows but they can reduce energy loss by up to 30%-50% which is well worth the higher price. The coating is placed directly on the surface of the panes of glass which lowers the U-factor of the window.
– Reflective coatings
Reflective coatings on glass can reduce the transmission of solar radiation but also block more light than heat. As a result, they gradually decrease the glare, visible transmittance of a window and the solar heat gain coefficient. Reflective coatings are common in hot climates because they can control the solar heat gain much easier.
