HOW MUCH BETTER WILL MY HOUSE RETAIN HEAT WITH DOUBLE GLAZED WINDOWS?
Depending on the type of windows we are replacing, the amount of glass your home has, and other potential heat loss causes, YOUR SAVINGS CAN BE VERY DRAMATIC!!! If you think your windows are drafty (which you can test by holding a lit match around the edges and watching the flame flicker or extinguish) there certainly will be considerable savings. Single pane windows transfer cold air by transmission as well as improper, old and broken seals that allow for cold drafts. You may be losing heat in many ways, so count on gaining efficiency in many areas.
