Should I Install Insulation in My Garage?
Insulating your garage depends on a couple of different possibilities. So before carrying on with the decision of whether or not you should insulate your garage here in Colorado, consider the following questions:
- Is your garage attached to your home?
- Is your attached garage under a finished room?
- Do you use your garage for activities including:
- Mechanic work
- Any other activities
If the answer to any one of these questions is yes, then you may want to consider adding some insulation to your garage. We will get into specifics later, but to put it simply: if you have a finished space of your house above the garage, you should think about insulating the ceiling of your garage.
Additionally, if you do not have a finished space above the garage, you should consider insulating the garage’s exterior walls (the ones that line the inside of your home).
Lastly, if you use your garage for recreational purposes (like the ones outlined above), you may want to consider insulating the interior and exterior walls. Insulating both would allow for year-round temperature control (interior) and temporary control while working (exterior).
Garage Insulation Challenges
People encounter many challenges when trying to decide whether or not to insulate their garage and rightfully so: garage insulation can be an exact science. Some of the challenges insulating garages stem from:
- Garages in Denver are rarely finished with the amount of attention that is paid to the rest of your home. Because of this, a garage almost never has a quality air barrier like the rest of your home.
- Garages are usually built or placed upon concrete slabs that are rarely insulated underneath. Insulating a garage by trenching around it and installing edge insulation is usually ineffective, very challenging, and extremely expensive. Because of this, the slab tends to be a huge cause of lost energy and heat within the space.
- Garages (even when connected to the home) are rarely connected to the duct system of the home. Because of this, the garage doesn’t experience the same treatment as the rest of the home.
- Because most garage doors are uninsulated, it makes it nearly impossible to air seal and insulate the space. Some preventative measures like foam board insulation can be taken to try and seal as much of the space as possible, but are usually not completely effective.
Insulating Garage Walls or Ceilings?
Whether or not you choose to insulate the walls, ceilings, or both in your garage depends on what you plan to use the space for. For example, if you plan on using the space solely for storage; such as for things like your car, tools, and others, insulating the outside walls may not make the most sense.
However, if there is a finished space above your garage, or if you plan on using the space for hobbies like workshopping or mechanic work, you may want to consider insulation along the exterior, ceiling, and interior walls. Bedrooms over the garage need insulation in the floor-boarding above the garage because they are heated and cooled.
If your garage is not below a finished space but borders a wall of the home, the same steps should be carefully considered. The same basic insulation challenges come into play, so your solution would be to insulate the wall that borders both the garage and the home. Due to CO2 concerns, this wall needs to be carefully and precisely sealed.
