Most heat escapes through gaps around windows. Failed sealant, gaps between the trim and the window, and bad window seals are the most likely culprits. With cracked caulk and missing sealant, a home becomes inefficient and may provide an entrance for bugs.
After finding the gaps, temporarily fix the leaks with caulk or weather stripping. For older windows that remain unopened, weather stripping can prevent leaks. (Hint: Be sure to measure the perimeter of the window and add at least 10 percent to account for overlap.)
For windows that open, do-it-yourselfers can replace the caulk themselves. Caulk does not completely seal the window, but it restricts air flow until the homeowner invests in a more permanent solution. After replacing the caulk, paint over it to complete the seal and protect the caulk. Caulking should be done annually.
Permanently fix drafts and increase home value with replacement windows. The most energy-efficient replacement window is made of insulated glass. Insulated glass units are multiple-pane windows with insulating gas between the panes. Thanks to the added insulation, insulated glass units reduce heat gain in the summer, and in the winter reduce heat loss. Plus, the energy savings pay for the windows over time.
For homes already equipped with insulated glass units, check for condensation between the panes. The “foggy” look of the windows indicates an insulation problem. Full-service glass shops can repair or replace bad units to restore your home’s energy efficiency.
