Single Glass Glazing
The single glazing is made up of just one layer of glass. It was very popular and used for many years, but global warming, the increasing costs for heating and cooling increased the need for efficiency. This level of efficiency could not be provided by the single glass glazing, as the single glazing provides very little energy efficiency with only an R-1 insulating value, and as a result of that its popularity dwindled. Generally, the thickness of the single glass ranges from 3/32” to 9/16”, and solar energy – both light and heat– easily passes through this glass making the energy loss considerable.
The single glazing is still in use, and people still buy it because it is cheaper to install. However, we would like to advise you not to get influenced by the pricing when planning the glazing of your windows and doors, as in the long run, the cheaper single glazing may cost you more to heat and cool your household.
