Should You Insulate Your Non-Insulated Garage Door?

Insulated Garage DoorYou’ve created the perfect space in your garage with insulated walls and ceilings and you’ve created a place where you enjoy doing your DIY projects or just hanging out. But, there’s one problem that keeps your garage from being a perfect project space – your non-insulated garage door. Is it worth it to insulate your garage door or should you just get a new one?

While a non-insulated garage door can be insulated, there are really only two ways to do it. You can get mineral wool blankets at a construction or renovation material store. They are typically $75 to $100 and the kit includes mineral wool rolls with a reflective plastic film.

Your other option is polystyrene insulating panels. These come from big box or chain hardware stores. However, because this material is flammable, you must also cover it with another material to keep it from igniting should there be a flame of some sort near it. These kits are typically made for a single door that is 8 or 9 feet wide and contain panels of insulation.

Disadvantages

Mineral Wool BlanketThere are a few downfalls to be aware of as well. Just because you insulate the interior side of the door, it doesn’t mean that it will completely stop the cold from penetrating. This is because a garage door is made from sheet metal and there’s no thermal break between the exterior and the interior. While it will likely help, don’t expect a huge difference.

Advantages

The one advantage though is that when you insulate a non-insulated garage door with a well-attached covering of mineral wool, you will improve the noisiness of a non-insulated garage door.

A Word of Warning

If you do insulate your garage door with either product, be sure that you do not add extra weight to your door. This can cause issues with your spring system. The spring system is calibrated based on the total weight of your currently non-insulated door. If you add more weight, the spring system must be adjusted accordingly.

Should You Do It?

Unfortunately, it’s really not worth it. If your door is noisy, then it may be. But if you’re trying to keep a garage cooler or warmer, then you’re better off changing out the door to one that is designed to protect you from the heat or cold.
