Shell Busey Blog - Upgrading WindowsJuly 5th 2017
Consider replacing single glazed windows with high performance windows. Major technological changes extend beyond glass itself to low-conduction spacers and frames. In the average home with conventional windows half the heat loss through windows goes out the cracks; much of the rest goes straight through the panes and frames.
Don't confuse standard double glazed windows which cost about 8% more but are twice as effective. Triple glazed are twice as good again. Low-emissivity windows (known as low-E) use an almost invisible metal coating to reduce heat loss, reflect outside heat in summer and block ultraviolet light which fades draperies, carpets and furniture. Best of all: two low-E panes with an insulating gas like argon between them. i.e. Smart Glass Low E with argon gives an R-value of 4.17
Budget first for your homes biggest problem areas: north facing windows (heat loss), large south facing windows (sun traps in summer) or windows in line with the prevailing winter wind.
