Insulation questions, answered by experts

While the ideal temperature for your garage is partially based on your preferences for a comfortable garage space, you'll still want to maintain a temperature between 40 degrees and 68 degrees Fahrenheit to protect your belongings and vehicles. If you are unable to maintain temperatures that fall within this range, then you may want to consider installing a heater in your garage to prevent temperatures from dropping below 40 degrees.

As long as your existing insulation isn’t compromised, you can add new insulation directly over them. Inspect your insulation thoroughly and make any minor repairs. Then, add new insulation on top of it. You must be completely certain that there is no contamination or mold growth before doing so. That said, when unsure, consider removing old insulation and lay down fresh ones.

Insulating an unheated garage can still be worth it. For instance, insulating an attached garage can help with heat loss from your house in general, and it can also make it easier to store electronics in your garage without worrying about them being exposed to extreme temperatures.

If you use your detached garage as a workspace, insulation can still make a difference. Plus, you can use space heaters and a window unit AC to help condition the space while you work without installing heating.

Yes, many professionals offer insulated siding for improved energy efficiency.

As long as a licensed professional installs your gas lines, you don’t have to do anything extra to prepare for cold weather. If there are pipes that require a wrap, your installer should have done it for you already. If you want to be absolutely sure your gas system is good to go for winter, the best option is to schedule a gas line inspection.
