An attached garage is a nice place to park your car and store your stuff, but it can also create a health hazard for everyone living in the house. The simple act of starting your car in the morning produces harmful carbon monoxide; and storing chemicals, fertilizers and paints can generate harmful fumes. These gases and fumes can enter into the house and make people sick.
Traditionally garages weren't air-sealed for exhaust fumes. The small penetrations in the walls between the garage and the living spaces could add up and, over time, lead to lots of harmful fumes drifting into the home. The door between the garage and the living space was usually made of wood and lacked weather stripping or a self-closing device to block the exhaust fumes.
The problem with using a wooden door is that it can catch fire. And without a self-closing device, the door could be accidentally left wide open for an extended period of time, leaving the house vulnerable to the many harmful fumes and gases of the garage.
So how do you keep these fumes from entering the house?
The best practice is to create an air seal between the house and the garage, preventing harmful fumes from getting into the living spaces. Keeping these fumes out begins early in the construction process and is only slightly different from current practices.
When it comes to the safety of the homeowner, taking the extra step to properly air-seal the garage and install a self-closing, fire resistant door is definitely the best practice.
Frames prove stronger and more energy efficient than conventional stud frames.
