Garage door insulation can be your survivor during the winter and summer times. It provides warmer, cooler, or even quieter space to your residential garage door. Moreover, it is designed to help you in lowering energy bills and street noise. Garage insulation cuts energy bills and street noise by serving as a barrier between you, your home, and outside noise. Also, garage door insulation is going to lighten your dark space.
Types of Insulation
Insulation, as well as garage door insulation, can be your best investment in a long-term residence. It can be such a budget-friendly project to apply an easy DIY garage door insulation, where it’ll cost you about $200 to insulate two 9-foot-wide doors (Home Advisor). Any insulation type will enhance the energy efficiency of your garage door.
The following are the most popular types to go for to the back of garage doors:
Ordinarily made of fiberglass, this kind of flexible insulation is frequently found attached into exterior walls. Commonly backed by paper or foil, it serves as vapor and air obstruction. Per inch of thickness, it has insulating values of R-3 to R-4. It will cost you about 30 cents per square foot.
Typically made from polystyrene, these rigid panels offer a high insulating value for relatively tiny thickness. Panels are mostly ranged from from 1/2 inch thick (R-3.3) to 1 inch (R-6.5). Foam board frequently is faced with aluminum or vinyl. The cost will be $20 for a 4-foot-by-8-foot sheet that’s 1 inch thick.
Reflective insulation, in rigid boards and rolls, provide highly reflective aluminum foil applied to one or both sides of insulation materials, such as cardboard and polyethylene bubbles. This sort of insulation reflects radiant heat, making it a good insulation choice for garages that heat up especially in summer or hot climates. It has approximate R-value of 3.5 to 6, depending on the way you apply it. (A 4-foot-by-25-foot roll is $42).
An uninsulated garage door definitely will cost you more money both in winter and summer. Studies done by garage door manufacturers prove that an energy-efficient R-18 insulated garage door can keep your garage about 12 degrees warmer in winter months and about 25 degrees cooler in summer. That lowers energy loss along the insulated walls and ceiling.
But, what exactly does R-value mean? According to Home Advisor, R-value is a calculative method referring to thermal resistance. It is also a thermal measurement unit for particular materials in association to how they insulate. Theoretically, a higher R-value means more heat resistance, which also means greater insulative qualities.
All insulation products have an R-value related to with them, and show it clearly on their packaging. Somewhat, R-value is a complex calculation, but the most important thing to know is what R-value you need, based on where you live and what type of space you are insulating, and select a type of insulation consequently. For instance, for you who live in colder climates require products with a higher R-value, while those in warmer climates need less R-value.
Indeed, insulating a garage door is worthy for many reasons. The main reason why someone might wish for insulating the garage is simply because they spend time in there. It can be ranged from woodworking, automotive tinkering or lifting weights on a home gym, etc. Those are some of many reasons why you wish for more comfy garage when you’re inside it. Opening a window or running a fan may help move air, but it won’t halt the heat from coming in which means only does little toward creating a comfortable space.
Steps prior to Insulating your Garage Door
Creating a more comfortable space for a garage which is attached to the house usually mean a bit more comfortable result for the room on the other side of the garage as well. Brief do-it-yourself steps to insulate your garage door are:
#1 – Gather Your Materials
You can shop two types of garage door insulation kits. As an example, a R-8 vinyl-faced fiberglass batting kit offers a relatively high R-value. It takes two kits to insulate a typical 16-ft.-wide garage door. Or you can buy precut R-4 expanded polystyrene (EPS) panel foam online. Simply cut each panel to length and bend and snap it into the horizontal rails on your door. However, at R-4 per inch, EPS has the lowest R-value, yet still it may enough for you who live in a moderate climate.
Then, you need to get doorstop vinyl weather stripping to seal the top and sides of your garage door. You may also require new vinyl bottom seal to fit your existing track, or purchase a new track if yours is battered.
#2 – Measure and Cut
After you have gathered all your materials, you have to measure the size of each panel frame in the door, namely the metal that frames the panel. Then, add about an inch to the shorter dimensions and cut the foil-faced foam board into the rectangles. The reason for adding an inch to the height of the rectangle is for obtaining panels that are somewhat larger than the real framing on the door, so that they are convex and curve outward when you put them in.
In fact, this step is definitely crucial because if you don’t make the air gap, then the foil will not function as a radiant barrier. This is particularly needed to primary reduce summer heat gain.
#3 – Finish It Up
Go on repeating step 2 for the rest of the panels. When it’s time to place the foam board into the frames, put the foam so the foil side is facing the garage door and the small air space you made from the convex shape. Begin by inserting the top edge in first, then “pop” in the bottom edge. The panels should be convex and have a curve outward that is visible when you look at them from the side.
When you’re finished, you will be benefited from a radiant barrier that acts as your first line of defense right after the metal door. Also the foam board will aid slowing down the little heat that makes it past the foil. As a result, you will have a brighter, more comfortable garage door, properly insulated to keep radiant heat out in the summer.
