Only a minimal amount of insulation is required for your garage door in order for you to reduce the costs of your monthly bills. While the majority of garage doors are joined on to the main living quarters of modern homes, the convenience of having a garage attached can often be offset by the challenge of trying to minimize the effect that the garage temperature has on the temperature of the living quarters. Providing your garage door with the insulation it requires will aid in preventing the fluctuations in temperature that accompany both harsher wintery weather and hot summers.

Insulating a garage door is a fairly easy process. If the garage door is not insulated at all then one simple solution is to install foam panels on the inside of the door. Foam panels are simple to work with – they can be cut to size with a cutting tool – and they can be purchased at almost any home improvement store in your locality. Fasteners or adhesives will be required for permanent foam panel placement.

A basic insulation kit containing both foam panels and adhesive materials can be purchased for around $100. These kits have the added benefit of containing instructions. While you may not initially be willing to part with $100 for an insulation kit, remember that you will begin to make savings and recoup that investment as soon as your insulation has been installed.

While the task of insulating your garage may seem like a large one, do not be overwhelmed! It is actually a simple task! Furthermore, you will reap the benefits of making your property more energy efficient. A little money and time spent on garage door insulation will ensure that your home is more comfortable but cost effective for you to reside in.

There is no doubt that integral garages can significantly affect the temperature of rooms adjacent to and above the garage area. The garage door itself can represent the largest single source of heat loss in your home and this all mounts up in terms of additional heating in the winter and cooling in the summer.

Just as your garage doors are the largest, most visible, yet most frequently overlooked aspect of your property, so the garage space itself is almost certainly the largest un-insulated space in your home. Like many so-called “green” initiatives, insulating this large space helps conserve energy which is not only environmentally beneficial but also translates directly into saving quite a bit of money (as well as making your house more comfortable to live in).

If you live somewhere that is not susceptible to extreme climatic conditions then a wooden garage door provides much better intrinsic insulating properties than a steel door since wood is a very good natural insulator. However, extreme weather and large temperature fluctuations can mean that because wood garage doors are already quite heavy they are effectively impractical when it comes to adding heavy duty insulation. In these situations a well insulated metal door may be the better option (there are many considerations to weigh up in the debate over steel vs. wood garage doors).

There are several methods of garage door insulation that you can use. One of the best ways of providing good garage door insulation is to check with the door’s manufacturer. Some garage door companies sell kits that are designed to work with their doors, which can make insulating the garage door very easy and effective, although the overall price might be a little higher. But if you’re in the market to buy a new garage door rather than upgrade an existing one then it makes a lot of sense to have this option pre-installed for you.

An off-the-shelf insulated garage door will look better, last longer and out perform an after-market kit. It is also possible these days to purchase insulated wooden garage doors, combining the quality and good looks of a traditional wood panelled door with a fully insulated metal one. These comprise an outer skin of real wood that has been professionally treated and finished to resist the elements and look great. The inner skin is again real wood, which can be finished in any style you can think of (faux wood panelling, fake interior walls, etc). Sandwiched between these two layers of wood is a thick layer of polystyrene insulation which provides superb insulation (often better than the walls) and also reduces the weight that would otherwise be present in a solid wood door.

Alternatively, you can purchase garage door insulating kits that are not designed specifically for one brand of door, but which work well on most garage doors. These generic insulating kits are often a bit less expensive than those provided directly from the door manufacturer but are still quite effective.

Garage door insulation kits use one of 4 basic materials:

• Fibreglass panels are pre-formed units covered with a protective, washable vinyl finish. They usually come with an integral fastening system and you would typically use about 8 panels for a single door.
• Foam panels are similar but consist of an expanded polystyrene interior with a laminated plastic covering to protect the panel and make it easy to clean. These panels are fitted into the channels of the door frame rails and a typical kit is usually sufficient for a single door.
• Insulating foam (polystyrene) is injected behind a plastic membrane that is fitted flush to the inside of the door; the foam then bonds to the surface of the door which keeps it in place and ensure complete coverage.
• Reflective foil is for solid (i.e. wooden) garage doors that thus don’t have the integral space and cannot take the additional weight of panel inserts. It is a very simple system whereby the foil is cut to shape and simply stuck to the inside of the door. It is generally available in varying degrees of thickness o suit.

You can also purchase your own garage door insulation supplies and do the job yourself without using a kit. There are three main areas on a garage door that benefit from insulation.

• First, you can use foam panels on the inside surfaces of the garage doors to provide extra insulation to the door itself, especially if the doors have glass windows.
• Second, the weather stripping on the sides of the doors needs to be in good condition. If this weather stripping has pulled loose or is in poor condition, this should be replaced to keep cold air from getting in around the edges of the door.
• Third, the garage door should have a compression bubble on the bottom edge that will effectively seal the bottom of the door when it is closed, keeping cold air from getting in. This should be checked, and if it is missing or it has become stiff, brittle or cracked, it should be replaced.
