There are a few areas around a home where air leaks 和 gaps can be easily identified 和 fixed by yourself. Some of these common areas include:

  • 视窗 和 doors. 嵌缝 and weather-stripping are two simple 和 effective air-sealing techniques that offer a good ROI. Caulk is generally used for stationary cracks 和 openings around doors 和 window frames, 和 挡风雨条 is used to seal components that move, such as doors 和 operable windows. 
  • 电源插座. Outlets located on outside facing walls are commonly overlooked when it comes to finding air leaks 和 gaps, but they are notorious for air leakage. A simple 和 effective fix is to install foam gaskets behind the outlets 和 switch plates.
  • 风管. Conditioned air escapes through incorrectly sealed joints 和 is lost to the unconditioned space where the duct is located. Duct mastic is inexpensive 和 easy to apply 和 can be used to seal these joints to prevent air leakage 和 increase efficiency. 
  • 阁楼舱口. Adding 挡风雨条 around the frame of your attic hatch as well as a foam board can help reduce any energy loss. And, if your attic hatch has attached stairs, an attic tent is also an effective option.



Some examples of air sealing 和 insulation issues that should be looked at by a professional contractor include:

  • 屋顶漏水导致水饱和绝缘
  • 将潮湿或潮湿的空气释放到阁楼而不是室外的通风孔
  • The presence of knob 和 tube wiring, which creates an elevated risk of fire if it lies within close proximity to fiberglass insulation
  • Recurrent ice dams in gutters 和 attics during the winter
  • Attic rafters 和 floor joists which are showing signs of rot or mold infestation
  • 阁楼通风不足
  • 嵌入式灯具,需要绝缘
  • 吹入式保温或大型泡沫气密性工程需要昂贵的专用设备,并且需要接受广泛的培训才能操作。

Calling in the help of a professional contractor will not only greatly improve the energy efficiency of your home but it will also raise the overall resale value of your home 和 make it more appealing to future buyers.
