Host Kevin O’Connor, contractor Nathan Gilbert and tech expert Ross Trethewey share some cost-effective ways to seal and insulate existing windows without replacing them. The team discusses efficiency ratings for older single-pane windows compared to today’s options and offers tips to seal your drafty windows from the inside.
They explain different insulating techniques, including using shrink wrap, weather stripping, and caulk. Anything you can do to decrease airflow and leakage will drastically increase comfort and energy savings.
在升级窗户之前,请尝试密封空气泄漏
视窗usually have an R-value of 1 to 2—walls generally have an R-value between 13 and 20. Before incurring the expense of buying a new window, homeowners should try to seal any air leakage around the existing window’s frame.
Traditional New England homes usually have storm windows to create a bigger barrier during winter. Nathan also explains a newer style: screw-in aluminum with removable glass for spring and summer.
How to Check for Window Air Leaks
- Look and feel around your windows.You can walk around your house and see any obvious cracks or holes where the building materials from your siding and window meet.
- Turn off your lights.See If there is any daylight coming through the sides or bottom of your window. Also, on a cold day, you can hold your hands an inch away from the window to feel for any drafts.
- You can rent a thermal camera从当地的硬件商店中,可帮助您检测窗户,管道和屋顶的能量泄漏,以及房屋周围的绝缘材料。
How to Seal Window Air Leaks
- 清洁所有要用肥皂和水填缝的区域,用腻子刀去除油漆或旧填缝。等待该区域干燥,以免在水分中密封。
- 在连续流中以45度角密封的区域涂抹填缝。确保填缝粘在接缝的两侧。如果填缝从裂缝中泄漏出来,请用腻子刀将其推回去。如果填缝缩小,请在平滑的线上重新涂抹,以完全密封裂缝。
How to Seal Leaks Between the Lower Window Rail and the Windowsill
- Clean the area where you will apply weatherstripping with soap and water. Let it dry.
- Measure the window width and cut the weather-stripping to size.
- 应用程序ly the weather-stripping to both surfaces and ensure that the material compresses to form a seal when the window is shut.
