What makes a home green? Home Air Sealing and Weatherization.
Imagine if your fridge were full of holes. If it were, then the motor under your fridge that works to keep the air inside cold, would have to work 24/7 to try and keep your food from spoiling. Well, have you have ever noticed that the air conditioners of some homes seem to also work 24/7? They do that for the same reason, because their outer shells are full of holes and they are constantly trying to cool the interiors.
Home air sealing and weatherization is defined by the EPA’s ENERGY STAR program as sealing and insulating the “envelope” or “shell” of your home, just like you would plug up the holes in your fridge.
It consists of sealing all the barriers to your home’s interior heat or conditioned air from escaping to the outside, and also unwanted external air and temperatures from entering. The home envelope includes its outer walls, ceiling, windows, doors, and floors.
The main culprits are usually wall and ceiling penetrations for plumbing and electrical pipes and outlets, light fittings, and the spaces around windows, doors, fireplaces and air conditioner registers.
The better a home is sealed, the less drafty it is, which means less energy is needed to maintain comfortable interior temperatures, which then results in lower costs.
Another benefit of home air sealing and weatherization, especially in Florida, is that less moisture-laden air in the form of humidity enters the home, which reduces the chance of condensation forming and turning into unhealthy mold and rot which can cause illnesses for the occupants, and is expensive to remove.
Sealing up joints, holes, gaps, and cracks where air infiltrations occur is a tricky business, since leaks are “usually” hidden from view. Home air sealing and weatherization contractors have been trained to find them and then to seal them up using high quality acrylic-latex caulk, fire- rated caulk and special insulating foam sealers.
Once a home is air sealed, it can be tested with diagnostic equipment to ensure that the job was properly done, and that all the leaks have been taken care of.
