Seal out the cold around windows Seattle Times
Q: I have a suspect about the newer Anderson windows with double-pane glass. Should one still hang a storm window to hinder further insulation?
My husband and I have a home that was built in 2003 and we would like to lower our utilities bills any way we can.
We have walls with extraordinarily insulation, but we realize the windows and doors are a great energy zapper.
We have noticed that some of the windows have mildew around them during some seasons. We have an Aprilaire system on our fervour pump system with UV light. It helps considerably.
Please give any additional advice to keep our environment and home safe and cost-effective.
A: Anything you do to add a thermal barrier between the inside air and the outside air or to simply prevent air infiltration to the home helps to spare energy.
Adding storm windows is both economical and energy-efficient as a thermal barrier even for new windows. The windows you have might have weighty air leaks, which allow condensation to promote mildew and mold growth.
