The Benefits of Air Sealing your Attic
Once the old insulation is removed, the next step is to air seal your attic, making it as tight as possible. The benefits of air sealing your attic are plentiful, and in this post we will highlight the top three advantages for the homeowner and inhabitants. During cold months, many of us use HVAC units to warm up our house. It is important to know that that heat rises up naturally to the top of the house, towards the attic. If your attic is air sealed, it will maintain the heat within the house, leading to a variety of positive benefits.
Provide cost savings by reducing energy bills
As noted, proper insulation will keep the rising heat in the house during the cold months, so that you will not have to spend as much money using the heater. But the same is true during the hot months. The air sealing the attic will actually improve the effectiveness of insulation installed and keep the hot air out of the house during these times, reducing your air conditioning bill. While you will have to pay some money upfront to properly seal your attic, in the long run, due to the above savings, you will end up saving a good amount of cash. It has been reported that proper attic insulation and air sealing can save you up to 50% on your energy bills.
Guards your house against potential moisture damage
This may not sound like that big of a threat, but it is actually quite serious. Rising heat which leaks out of a house can melt snow, which leads to ice dams, which in turn can cause long-term damage to your roof. Roof damage can be very expensive to fix. Furthermore, the insulation itself can become wet, which will lower its effectiveness, which in turn allows more heat through, exacerbating the problem. You can nip this potential cycle in the bud by properly air sealing your attic.
Improve overall air quality of the house
With a well sealed attic, you will not have to use your HVAC unit as much, since the heat will be maintained better within the house. Using your HVAC unit less will actually be better for the health of the inhabitants since heaters are known to have a carbon footprint that can be bad for your health. Furthermore, a properly sealed attic will also stop the house from having sudden changes in temperature, and will also block many potential drafts. With a properly sealed attic, inhabitants can enjoy a consistent air temperature, free from annoying, and even unhealthy, drafts.
