Having an attached garage can be a nice luxury, especially when it comes to accessing your vehicle without having to leave the house. Unfortunately, many attached garages are constructed with minimal insulation or no insulation at all. This can be detrimental to your indoor air quality, safety, and overall comfort. An insulation company can come out to your home and make recommendations for adding insulation to your existing garage--and for good reason.
1. Protect Your Indoor Air Quality
When you park your vehicle(s) in an attached garage, fumes from your car's exhaust inherently make their way into the air. Without proper insulation between your garage and home, some of these fumes are bound to make their way into your house. This is especially a concern if you have any bedrooms located directly above your garage. Adding insulation to your garage ceiling can help prevent exhaust gases and other fumes from affecting your indoor air quality.
2. Enjoy Added Comfort Inside
When an attached garage lacks insulation, this can also affect the comfort inside your home. During the cold months of winter, frigid air from the garage may make its way into adjacent rooms. During the summer, heat from your garage will rise into rooms located above the garage, making for an uncomfortable situation and causing your HVAC system to work harder than it should have to.
3. Potentially Save on Energy Bills
The harder your HVAC system needs to work, the more you'll also end up paying to keep your home comfortable during times of extreme temperatures. Adding insulation (including insulated garage doors and access doors) to your garage can help keep your home more comfortable, reduce wear and tear on your HVAC unit, and save you money on your heating and cooling costs.
4. It Might Be Required
Check your local building code--especially if you live in an older home. Many cities now require that attached garages be built with at least some insulation, regardless of whether the garage itself is heated. While it's unlikely your local code enforcement agency will find out if your garage isn't insulated, you may have a hard time selling your home down the road if it isn't up to current building codes.
Having your garage insulated will cost some money up-front, but when you consider all the benefits you can enjoy from a properly insulated garage, many homeowners would agree that it's an investment that pays off.
