subject: Storm Windows Keep Cold Drafts At Bay [print this page] Bay windows create three openings in the shell of your home compared to one opening for a standard window. If your bay windows are old, single-pane windows, your problems may be compounded by air leaks that increase monthly utility bills. Bay windows also are exposed on three sides to prevailing winds, precipitation, and expansion and contraction by daily temperature swings. Replacement windows would be the ideal solution, but if they simply aren't in your budget, installing storm windows on your bay windows reduces both draftiness and monthly costs. Be sure to repair and re-caulk old windows first.
Temporary Interior Storm Windows
Some storm windows fit inside existing windows. These are solid panels of glass, acrylic or polycarbonate which do not permit operating your built-in windows for ventilation. Often they are put up only during cold winter months, and are great for creating a dead air space which can increase insulation significantly. Properly installed they will reduce drafts and last for many years. Take care not to scratch non-glass interior storm windows.
Exterior Storm Window Options
Exterior storm windows fit snugly against the exterior frames of your bay windows. They can be installed permanently and caulked after installation. Many come with a movable glass panel and an insect screen panel so they can be opened for ventilation just like the underlying built-in window. They'll help preserve historic windows or may simply make that bay window's built-in window seat as comfortable to use in the winter as it is in the summer.
Accurately measuring and installing either interior or exterior windows is crucial to them performing their job. Ask your storm window dealer how it's done, and if you have the capability, the job doesn't take long. If you have any doubts, get the most from your investment with professional measuring and installation.
