    As the weather cools, it's time to winterise your garage, especially if your home workshop is there. Metal garage doors block winds but don't regulate temperature. If you can't afford a new, pre-insulated garage door, consider upgrading your current one. We've gathered all the info you need to insulate a garage door, plus tips to maximise the project's benefits.

    Most homeowners struggle to keep their garage cool. Keeping a room at a constant temperature when the door is opened often or left open for hours can be difficult. Garage temperature swings can damage tools, cars, and toys. Uninsulated garages can also increase energy costs. There are ways to make your garage comfortable.

    Why Insulate the Garage?

    Insulating a garage has many hidden benefits. Energy conservation helps maintain a consistent temperature, for example. You won't have to overwork your A/C, lowering your energy bills. Insulation blocks sound. The buffer can contain street and home noise. Do you often use power tools in your garage? Soundproofing keeps neighbours happy.

    Areas to Insulate

    Insulating the garage is necessary for three primary areas: the ceiling, the walls, and the floor. If you are unable to properly insulate all three areas, you should at least address the ones that you are able to. Insulating even a single section is preferable to not insulating at all; however, if you are interested in taking care of the other sections as well, you should think about investing in a professional service that can assist you in reaching those sections.

    Garage Door

    The overhead garage door is typically the part of the garage that is the least thick and serves as the primary barrier to the outside world. The vast majority of doors are constructed from lightweight aluminium, which reacts to changes in temperature. As a consequence of this, we strongly suggest investing in some insulation, particularly in the event that the garage is connected to the house and shares a wall with it.

    Insulating the garage door is the activity that requires the least effort and the least amount of money. You can buy a variety of different types of insulation that you "stick on," as well as kits that include everything you might require. You also have the option of purchasing a brand-new door that already has insulation installed.

    The Attic/Ceiling

    The space above a lot of garages is used as an attic. The average homeowner utilises this wide-open, draughty space for the purpose of storing their belongings. However, what many people do not realise is that having an uninsulated attic wastes both energy and money. Similarly, if there is a bedroom above the garage rather than an attic, the same idea can be applied to that situation as well.

    In this scenario, it would be a good idea to insulate the ceiling of the garage. Installing insulation in this space presents a greater challenge for do-it-yourselfers, but the task is not impossible. If you don't feel comfortable tackling it on your own, there are many professionals available who would be happy to assist you.

    Garage Walls

    Easy wall insulation. Huge rolls of insulation can fit between studs. Assuming your garage's studs were properly spaced, the process is simple. Unroll insulation from ceiling to floor, staple, and repeat. Before buying insulation, make sure it has the right R-value for your garage's climate. R-value measures heat resistance. Higher insulation value. If you live in the north, a higher R-value will better insulate your garage from cold winters.

    Insulation is essential for energy-efficient homeowners. Insulation stops air from escaping stud cavities, attics, ceilings, and doors. This saves money on heating and utility bills. Before installing insulation in your home or hiring a professional, know the types and their benefits.

    Why Should You Learn How to Insulate a Garage?

    These are the top reasons homeowners insulate their garage:

    • To reduce the transfer of heat and cold from the garage to the house and vice versa. Insulation reduces the amount of work your furnace and air conditioner have to do, lowering your carbon footprint.
      to save money on utility bills
    • To make the environment quieter by reducing the amount of noise coming in from outside.
    • To help keep potentially hazardous gases out of the house (like solvent fumes).
    • To create a liveable space or workshop that can be efficiently heated in the winter or that, at the very least, does not experience the extreme temperature fluctuations that a garage without insulation does.

    It doesn't matter if your garage is attached or detached from the rest of your house; either way, it has the potential to become a very useful space. Insulating your garage on your own can be a hassle-free and relatively simple way to improve the space and make it more valuable — not only for you and your family right now, but also in terms of its potential resale value in the future.

    What Can I Expect from Insulating My Garage Door?

    Adding insulation to the channels on the interior of the door can help keep the temperature inside your garage 10 to 12 degrees warmer on average during the winter and up to 20 degrees cooler during the summer. Since insulation also lessens the transmission of noise, not only will you not be able to hear the street traffic when you are in your workshop, but you will also spare your neighbours the sounds of your son's rock band practising.

    Benefits of a Garage Door Insulation Kit

    Insulating a garage door with a kit that contains either vinyl- or foil-faced batts or foil-faced rigid foam boards is the quickest and easiest method. Kits are available at home improvement stores. Kits start at around $50, and as the price goes up, they typically include a complete set of supplies in addition to the insulating materials themselves.

    These supplies can include adhesive, tape, a utility knife, gloves, and possibly even a dust mask. However, the retainer pins in a kit are specially designed, which is the kit's primary advantage. The plates that are attached to the pins are made of lightweight plastic or metal and adhere to the back of the garage door channels to help anchor rigid foam or batts in place.

    The pins themselves are made of lightweight plastic or metal. Insulation is stabilised in this way, preventing it from falling onto your vehicle when the door is opened. Alternate strategies are available to you in the event that you decide against purchasing a kit to secure the insulation in place.

    Purchase the Right Rigid Foam Insulation

    Skipping the kit? Most DIY-ers opt for foil-faced rigid foam board panels that you measure and cut with a sharp utility knife or table saw to fit the channels inside your garage door.

    • EPS, XPS, and polyisocyanurate are the main types of foam board (called "polyiso" or simply "iso"). Any of these are acceptable as garage door insulation if foil-faced and fire-rated. Non-faced foam board is flammable and produces dangerous fumes when burned; it may violate local building codes.
    • Choose foam board thinner than door channel enclosures. A standard garage door channel is 1-3/4 inches deep, so you'd need 1-1/2-inch foam board.
    • Most garage door channels have "lips" that hold the boards, but rigid foam boards can rattle if not snug. Before inserting the garage door channel, apply foam-safe adhesive to its back. If needed, expanding foam can seal side gaps, but a little goes a long way. Some adhesives will melt foam board, so read labels before using.

    Working with Batt Insulation

    Standard batt insulation is readily available and often cheaper than foam board, but it's not the best choice for garage door insulation if you're not using a kit. The thinnest standard batt is too thick for most garage door channels, and compressing the batts reduces their insulation ability. If you want batt insulation, look for 1-12-inch foil-faced batting at plumbing supply stores or online (DIY stores don't carry it). To secure the batts, use the manufacturer-recommended adhesive and tape.

    How to Insulate a Garage Door

    Measure, mark and install the retainer pins.

    Find using measurement the point that is 12 inches away from each edge of the panel and that is in the middle of the space between the horizontal rails. Make a note of the location. After that, remove the backing paper from the adhesive, and adhere the retainer pin base to the panel by pressing it down. Each panel should have two retainer pins installed in it.

    Cut the batting

    While the vinyl-coated side is facing down, roll out the batting and mark the cutting lines. On a piece of scrap plywood, lay the batting. The insulated garage door should then be compressed with a straightedge, and a utility knife should be used to cut it.

    Lock the batting in place

    Put the insulation in place so that it is centred in the panel, and then press it against the retaining pin in such a way that it makes a hole in the vinyl facing. After that, place the retaining cap over the pin and push it down until it clicks into position.

    Because we opted to go with the R-8 fibreglass insulation kit offered by ADO Products for our door, we won't be walking you through the process of cutting and installing XPS foam panels in this narrative.

    Wash each door panel with spray and rags. Rinse and dry. Install retaining pins. For a snug fit, measure each panel's height and width and add 1 in. Measure each panel as you go rather than pre-cutting them based on one measurement. Insert insulation with the vinyl side facing the garage. Attach the retaining pins. Insulate all panels.

    Mount the doorstop weather stripping

    Put the doorstop against the top and side jambs and angle the vinyl weather stripping to a 45-degree angle before closing the door. To keep it in place temporarily, use nails that are only partially driven into the wood.

    Readjust to accommodate door movement

    Simulate wind by pressing on the door. Move the doorstop inward to seal it. Check the side gap in several places and adjust as needed.

    Tack the doorstop weather stripping to the top jamb. Same for side doorstops. Then press on the door to simulate wind movement. Adjust the doorstop so it seals in wind. Hammer in the nails. If the door has too much play to adjust the doorstop properly, replace the hinges with spring-loaded versions that press the door against the weather stripping at all times.

    Install a new bottom seal

    Insert a screwdriver with a wide blade into the crimped area, and then turn it so that the aluminium track is gently worked out. It will be repeated at both ends of the track.

    Slide in the new bottom seal

    Spread some dishwashing detergent along the slots that run along the bottom track, or spray some silicone onto the slots. After that, put the vinyl seal in place, and then pull it tight. Remove any excess vinyl using a utility knife, then use a pair of pliers to crimp the two ends of the track.

    The majority of vinyl seals for steel doors are held in place by a track that runs along the bottom of the door. The sun's rays can cause the vinyl to become brittle, causing it to crack or break apart in sections and let in chilly air. In order to keep the seal in place, track installers typically crimp the slots at each end of the track. Remove the old seal by loosening the crimps and sliding it out. After that, put the new one in place.

    Test the door

    If you lift and release a properly balanced garage door, it should stay in place. Insulation adds weight, which can throw off the door's balance. If your door falls when you let go, have the spring tension adjusted. Unbalanced doors can damage openers.

    Insulate your garage walls, doors, and ceiling if you plan to add a heating or cooling system. Remember flooring. An epoxy floor coating adds protection but not necessarily insulation.

    Use batt or blanket, blown-in, or spray insulation. Spray insulation should be done by a pro and requires preparation. Batt and blanket are discussed.

    Insulation can keep outside noise out of your garage and your activities from escaping to your neighbours or the rest of your house. New batt or blanket insulation adds soundproofing. This extra layer of vapour is no harder to instal than batt and blanket insulation. Higher R-values are better for insulation. This is limited by wall thickness.

    To prepare:

    1. Determine the area of the space you plan to insulate and add 10 to 20 per cent to account for mistakes and odd spaces you need to fill.
    2. Count the spaces above doors and windows.
    3. Measure the space between joists and studs to determine the width of the insulation you need.

    These are typically spaced at a distance of 16 inches on centre, but the exact distance between them can vary quite a bit.

    Choose the kind of insulation you want. Even though blankets and batts are typically made of fibreglass, there are many natural material alternatives that can be used instead. Finding one that isn't manufactured with formaldehyde should be a top priority regardless of the type you go with.

    Your total square footage should then be divided by the amount of space that is covered by a single roll of insulation or a single package of insulation. The number of insulation packages that you require will be determined based on this. Install according to the instructions, typically cutting the vapour barrier to size and using a staple gun to attach it to the studs.

    If you are replacing your garage doors, you should instal insulated doors if at all possible. Purchase a retrofit kit that will add insulating panels if you are going to be using old doors that are not insulated.

    During the winter months, installing interlocking foam or PVC mats can make the floor a little more bearable to stand on. They will provide some degree of insulation, but their primary function is to keep the floor warmer and cushier underfoot. They will also provide some degree of insulation.

    Maximizing Your Insulation Project

    Replace the rubber sweep that is located at the bottom of the garage door in order to get the most out of your garage door insulation project. Additionally, you should instal weather stripping around the sides of the garage door in order to stop frigid draughts from entering the building. Even though insulating the doors is a good place to start, you'll get the most out of your investment in heat retention by insulating the rest of your garage as well.

    Heat can still escape through a garage's roof or sidewalls if they aren't insulated. But regardless of the actions you take before Old Man Winter pays you a visit, your workshop will be warmer as a result of your efforts. However, we must caution you that there will be no room for you to make excuses once you are inside.

    FAQs About Garage

    Fiberglass roll insulation is the cheapest and easiest type to install, provided that your garage's interior walls have not been constructed. Unroll the insulation between the wall studs with the vapor barrier facing the inside of the garage.

    An insulated ceiling is especially important if you've got a living space above the garage. During the summer, the heat's inexorable journey upwards will find it creeping into the room above, undermining the air conditioning and raising its costs. Winters, in turn, will be cold and drafty.

    The bottom line is that insulating even an unheated detached garage can make it better by making it more livable and prolonging the life of your car and other precious belongings. It does not cost much and you can do it yourself.

    There are two main ways to insulate a concrete garage. The first is to use a fibreglass insulation much like the type found in any typical loft. The second is to use a coated foam sheet like the ones manufactured by Kingspan or Celotex.

    The most common types of insulation for garage walls are fiberglass batts (pictured to the right), spray foam insulation, and blow-in cellulose insulation. If your garage already has insulation installed, have a professional inspect it to determine whether an upgrade is warranted.
