While we’re taking definitive strides in our quest to make our homes perfectly energy efficient, we’re not there just yet. In every aspect of home design and building, top priority is given to energy efficiency, and window glass is no exception. Traditionally, doors and windows have been two of the weakest points in home insulation.
Thanks to leaps and bounds in
window glass technology, this is no longer true. If you are remodeling your home, or building a new one, there are some important factors to consider when choosing the new doors and windows.
In terms of windows, glazing is a process when two separate panes of glass are hermetically sealed together, leaving a space for air between the two panes – like this:
The extra glass, coupled with the air space, resists the flow of heat – making the window energy efficient.
Two other important window glass considerations are R-value and U-value.
-
R-Value: This determines the amount of heat lost through the window. The higher the R-value, the more it prevents heat loss. Typically, a single-glass pane has an R-value of 1, whereas a double-glazed window has an R-value of 2, effectively doubling energy efficiency.
-
U-Value: This is a measurement of how much heat escapes in an hour. The lower the U-value, the more efficient the door or window is.
Window glass is definitely the crux of energy efficiency in your home so choose wisely. Ask your local
window supplier for advice to ensure that the money you spend is a valuable investment.
