In extremes of temperatures where AC or furnace are used in huge amount, energy consumption is heightened to a great deal. If any way of saving energy bills can be invented in such cases, it can be a real big help. Insulation can serve this purpose. Though insulation is a process to be executed with utmost care for your entire house, the garage insulation is a different story altogether. It is really very tough to make proper insulation in garages. In places where temperatures can fall to single digits, it becomes extremely important to keep the garage above a certain degree of heat to keep the car engine, paint and other stuff like caulking tubes in proper condition. However, attaining quality garage insulation is a bit easier in warm climates.

    The best way to make your garage a little more comfortable is to prevent the cold or hot air, moisture and unwanted noise from infiltrating into your garage from the outside. Hence, it is very important to insulate the walls of the garage along with the doors. The garage walls facing outside or the inside of your house can also make your garage lose ample heat thus causing harm to your car and other necessary parts. Hence, the roof and walls have to be installed with perfect insulation for securing the best effects. The need for a heater or cooler to keep the garage temperature correct is also reduced which saves a lot from your pocket.

    Though various materials can serve the purpose, a great way is to go for expanding foam. Since, they are built up with technologies that harden them even more when they come in contact with the air, they serve as amazing insulators for the garage which is opened wide apart every time that you get inside or outside it. Another solution is to have a small door entrance from outside that will not make you open the entire door wide apart except when you take your car in orout.

    Garage insulation especially for the doors can be achieved with the help of great insulation kits containing already cut insulation, fasteners or tapes and gloves with utility knives. It has become a Do-It-Yourself job in most cases but it is still advisable to take up a garage professional to make your garage insulation defect-free.


    There are various types of garage insulation that can be fitted to your garage. The most popular among them are:-

    1. Batt insulation-This is the flexible fibreglass insulation stuffed into exterior walls and backed by paper or foil. With an R-value of R-3 to R-4 per inch of thickness for garages, its cost comes to 30 cents per square foot.
    2. Foam board insulation-Typically made from polystyrene, these rigid panels can provide a high insulating value for relatively little thickness. They are often faced with aluminium or vinyl. With R-value ranging from R-3.3 for ½ inch to R-6.5 for 1 inch, this type of insulation cost $20 for a 4 by 8 foot sheet with 1 inch thickness.
    3. Reflective insulation-In this type, highly reflective aluminium foils are applied to one or both sides of rigid boards and rolls such as cardboard and polyethylene bubbles. This is great way for reflecting radiant heat. With an approximate R-value of 3.5 to 6, it costs you $42 for a 4 by 25 feet roll.

    Of course, budget is an important factor. But since, the door comprises the major part of a garage, what becomes more vital for choosing your garage insulation is the material by which you garage door is made. The aim is to install a matching and suitable installation for your door that will be appropriate to the climate. Here are given the best ways to match your garage insulation to the door:-

    1. For steel doors-These are the best for insulation as they can accommodate any type of insulation. All you have to do is to stuff the flexible insulation in the frames around the panels in case of fibreglass insulation or squeeze cut-to-fit foam board insulation into the frames. Having steel doors can undoubtedly provide your garage with the most effective garage insulation.
    2. For wood-frame and panel doors-In this case, you need to cut and fit rigid insulation into the recesses between the door frames. Since, wood and panel doors in garage cannot accommodate as much insulation as steel doors can, you may need to install two layers of garage insulation for better and more effective climate control.
    3. For flat garage doors-If your garage has a door without panels, the most appropriate insulation for it will be foam board or reflective insulation. In this case, the need is to simply glue or tape the insulation to the garage doors. However, this may require maintenance at regular intervals for keeping up the effect.
