How Tightly Should You Seal Your Home?
admin • March 22, 2012

More and more products, like high velocity heating systems , and solutions are available to Welches residents these days to help seal our homes off from the outside world. The idea is that by keeping outside air out, our homes are more energy efficient and healthier, because all pollutants and pathogens are barred from entry.

This is a good idea in theory, but it can have its drawbacks. Most notably, sealing your home up too much can be bad for your family’s health. If your home is sealed too tightly such that there is not enough air flow from within the home to the outside and vice versa, then the indoor air just…stays indoors.

That means that all the sneezes, coughs, dust, dander, smoke and carbon dioxide stay inside with it. All that stuff can make you sick, completely flying in the face of your efforts to stay healthy by sealing your home.

Now, that’s not to say that sealing your home is a bad thing. Using LEED glass in your windows does keep heat in and increase heating efficiency. Air cleaners do help eliminate pollutants and pathogens from the outside than can make you sick. Good insulation and intact ductwork do help keep your home comfortable and efficient in both the cold and hot months.

So, sealing your home is not a bad idea. The trick is to not go overboard and seal it up so tightly that you are crossing the threshold from having a healthy home to having a giant Petri dish. You want to have a home that is insulated, but not vacuum sealed. You want a home with filtered air, but still plenty of air exchange with the outside world.  Thankfully, mechanical ventilation is a way to both keep your home energy efficient and keep your indoor air from getting stale.

To help you with this endeavor, there are guides available online, such as at the ENERGY STAR website. In addition, it is a good idea to call The Clean Air Act  and ask plenty of questions when building a new home or making improvements to your current one. A qualified technician will know how to insulate and ventilate your home properly to protect your family’s health.
