Walking out to a garage on a freezing January morning in Billings, MT often feels like stepping straight onto the open plains. Homeowners in Billings already know how brutal winter cold snaps and summer heatwaves can be for local properties. Apex Insulation Co receives many calls from residents trying to figure out the best way to tackle garage temperature issues. Homeowners in Billings often have questions about garage insulation.
Do I actually need to insulate my garage if it isn't heated?
Even if you do not run a heater out there, insulating your garage makes a big difference. An uninsulated garage acts like a giant thermal sink, bleeding heat right through the common walls and floor of your actual living space. When the wind kicks up off the Rimrocks, that uninsulated box pulls heat straight out of the rooms adjacent to or above the garage. Plus, if you store gear, paint, or canned goods out there, you will avoid that harsh freeze-thaw cycle.
Should I worry about insulating the garage door too?
Yes. Putting insulation in your walls and ceiling does not do much if your garage door is a thin sheet of single layer metal letting all the air slide right through. Homeowners need an insulated garage door or a retrofit kit. Without it, you are leaving the biggest opening completely unprotected against the weather in Billings, MT.
Can I use fiberglass batts, or do I need spray foam?
Both work, but they serve different purposes depending on how you plan to use the space. Fiberglass batts are a common, budget-friendly way to fill up standard wall cavities between the studs. However, if you want to stop air drafts entirely and get a higher R-value in a tighter space, closed-cell spray foam is very reliable. Here in Yellowstone County, where temperatures swing wildly, spray foam handles moisture and sealing better than anything else.
Will insulating my garage cause moisture or ventilation problems?
It can if you seal everything up tight without factoring in ventilation. Garages see a lot of moisture, including melting snow dripping off your truck in the winter or heavy humidity in the summer. If you use spray foam, it acts as its own vapor retarder. If you go with batts, you might need specific vapor barriers depending on how your garage is framed and whether there is a living space above it.
How long does a typical garage insulation project take?
Most standard two-car garages can be wrapped up pretty quickly. If Apex Insulation Co is installing batt insulation or putting up blown-in material, our crew usually knocks it out in a single day. Spray foam applications might take a bit longer depending on prep work and curing times, but you will not be displaced from your house for a week either way.
Does insulating the garage actually lower my energy bills?
Yes, absolutely. Because most attached garages share walls and ceilings with the main house, any conditioned air leaking into the garage, or cold air pushing inward, directly affects your HVAC system. Homeowners routinely notice their living spaces hold temperature much better once the garage envelope is properly sealed up, which takes the heavy load off your furnace and air conditioner. For homes in Billings, Apex Insulation Co is here for all your garage insulation needs.
