Hidden Air Leaks in Homes
More air leakage takes place in your home in areas that you don't know about. Usually, homeowners will have all the easily visible leakages fixed and think that their living area is fully protected.
Chimney Effect – There have been air leaks in your home and you have never known it, and you continue to lose energy to it through the chimney effect. So what is the chimney effect? Hint – it has nothing to do with your chimney!
Cold air will enter your foundation through leaks or cracks and start rising as it becomes warm inside your home. It will move to your attic because of holes, from leaking duct work, or because the attic floor has been poorly sealed. This movement of air will thus remove the warm air form within home and you don't even know about it. Your heating system will continue to work harder to keep up with the loss of energy.
Only an experienced air sealing and insulation expert will know how to fix the leakages and cracks in your foundation and attic floor to prevent the chimney effect from taking place.
What are the Benefits of Proper Air Sealing?
There are many benefits of having proper air sealing in your home.
Improved comfort – when the leaks are all sealed and the insulation is comprehensive, you will be improving the comfort within your home. Some of the additional benefits that come with include the following:
• Improved control over humidity (remember if there is no control over humidity, it can play havoc with the interior comfort)
• Minimized chances of having ice dams on your roof during the winters
• Lesser chances of pests, dust and pollen entering your home
• Reduction in outdoor noise from entering your home
Air Sealing Vs Insulation
I have been asked this question many times – what is more important? Air sealing or insulation? I will say that both are essential to creating a more comfortable, energy efficient and durable living space. But in the order of preference, I will say that air sealing comes first.
Improved Energy Costs – Proper air sealing improves comfort by reducing the drafty area in your home. It will improve the air quality by preventing outdoor air from entering your home through basement or crawlspace. Besides, there is lesser threat of mold development in your attic.
Most homeowners think that the drafts or air leaks take place around our doors and windows. But I can tell you that more leakage is taking place from your basement and attic than you know about. These leakages are adding up to your energy bills and you don't know about it. So when you hire someone to upgrade your home insulation, ask them to ensure total air leak in these two important areas of your home.
