What is the rationale for the storm window? Energy Loss or Sound mitigation.
What is the rationale for the storm window? Energy Loss or Sound mitigation.
Ok, I'm not sure what I'm looking for - so far, I have not noticed any condensation on any of the south facing windows and only a small amount on the smaller double hung windows - all of which are on the north side.Before reaching too deep into your pockets I'd recommend doing a test on one window with a less expensive product like Visqueen and tape to determine how much or if any condensation forms because of moist gas and the window pane surface possibly being below dew point temperature.
Yes, they are.Are the existing windows double pane?
I have looked at these and a sample of their prices. Not sure I want to deal with a thin film that can be punctured on these large windows. Most of them are at a level that maximizes the view - which the grandchildren love year round. We have (5), ages 3 and under right now, and God willingly, there will be that many more! Telling them to "stay away from the window" is not an option.We put double glazed interior storm windows in our home a couple of years ago, our existing windows were only 4 years old but it was cold near them. The interior storms really did the trick, we couldn't be happier. These windows are manufactured using an perfectly clear film that has a 3/8" dead air space between the 2 layers of film. They look very nice and we didn't need tools to install or remove them in the spring. There was some condensation on my windows on extremely cold days but after installing these that problem was solved also. I just ordered more of these for my office. We bought ours from a company in Wisconsin called ....................I like their product and the price but the double glazing was the real selling point. Ad Removed

That being the case, are you certain that the windows are your primary energy loss?Yes, they are.
We can probably have the utility company come and do an energy audit and have them take a picture with an infrared camera to know that for sure. The house was built in 1965, but all the windows were replaced in 2004, as well as the house was wrapped, then insulation and vinyl siding.That being the case, are you certain that the windows are your primary energy loss?
There are usually a whole host of other locations to address beyond double pane windows and putting a storm on them may not improve the total R-Value as much as you are hoping for while they will impede the look.
We are in Minnesota - just north of the cities.Where are you located James?
We have triple pane windows on our house and Fairviews comment is quite valid. When the temps drop, we get a little condensation on all windows but especially on windows where the blinds are pulled down. So much so we have to wipe them with a towel when we lift the blinds. We try to keep our humidity inside the home high because of the wood floors and we can get some cold temperatures.
I wonder how much of the cold drafts you are experiencing are from the double pane glass as opposed to air flow infiltrating around the windows.
Oops, forgot to add that I wonder if condensation between the double pane and storm glass is possible when it get extra cold.
Good ideas.Not all double pane glazing are same. It is possible your windows are double pane, but only dry air in between. This doesn't do the job as well, and you may be feeling the draft created indoor side of the windows, not air infiltration.
With canned smoke, check around the window trim, around recessed lights (if you have them), around outlet/switch covers, around base molding. Having insulation done and house wrapped do not mean that points of air infiltration were taken care of. Without gutting the interior, blown in, dense pack cellulose gives the best value for air/insulation.
Plexi glass is expensive, and will not stay clear. Just cleaning the plastic will scratch it and dull it over the years.
If you have hot air furnace, cold spots in areas or between cycles could feel like draft.
