Looking for an actual number, not a quot;go call the builderquot; response. I already did that. Still looking for an actual savings amount though. Anybody do this and can give an example of energy savings?
How leaky are your windows? How many panes? Is there insulation around your windows? Are they caulked properly? What is the normal temperature outside? This is not something anyone can throw a number at you that makes any sense. There are to many contributing factors to come up with a savings number. Suffice to say if there is cold radiating in from the window - or heat in the summer your bill can only benefit from sealing them. The heat shrink plastic adds another thermal layer. It's like putting on a sweater under your coat if it's really cold. I live in Winnipeg Canada. In the dead of winter -40F is not uncommon. In this old house most of our windows are triple pane. The ones that are not actually get a layer of ice on the inside. We plastic those and plan to replace them.
Add figures for size of window, type of heating system, where you live, etc. Then the application will do the calculation.
