Sealing windows for winter is a crucial task to keep cold air out and reduce energy costs. Begin by applying weather stripping around the window frame, and using caulk to seal any gaps. Window insulation film can also provide an added layer of protection from drafts.

Winter window sealing helps maintain a warm indoor temperature while reducing heating costs. Weather stripping and caulking fill in small gaps, while insulation films add an extra barrier to prevent heat loss, making these simple methods effective for keeping your home comfortable during the colder months.
