Benefits of Garage Door Insulation

Posted by Guardian Garage Doors on 19th February 2021 -

You probably know all about the benefits of insulation, but how can it be applied to your garage door? In this article, we’ll be going through the benefits of garage door insulation and how to go about it.

How insulation works

Heat flow involves three main processes: conduction, convection, and radiation – we are dealing with the first of these three. Conduction refers to how radiant heat moves from hot to cold through solid materials, e.g. the way heat moves through your garage door to the outside of the home.
So, heat flows to wherever it is cold – insulating materials work to slow this process down by providing a thick barrier between the hot and cold areas.

Advantages of garage door insulation

The obvious benefit of garage door insulation is warmth. If you’re the type of person who always has some sort of project on the go, insulation means you can tinker away in the garage without feeling the chill. If you keep your car in the garage, insulation will protect it a little more from the elements, preventing its battery and fuel from being affected by the cold.

Less heat escaping from the garage also results in better energy efficiency for your home. This means you will be spending less money on heating your property.
Another benefit of a layer of insulation is the fact that it provides a level of soundproofing. Of course, for most people, sound pollution is not an issue that tends to stem from the garage – but if you’re doing work that makes a lot of noise, or your band has evening jam sessions in the garage, it might be an advantage.

Types of garage door insulation

Foam insulation is made from polystyrene or polyurethane and comes in thick sheets or a spray form. Foam insulation has a high level of thermal resistance. It’s important to remember not to buy non-faced foam board as it’s dangerously flammable.

Batt insulation is flexible so it can be stuffed into exterior walls. It’s usually made from fibreglass and backed by paper or foil to prevent heat flow. This isn’t the best material for garage doors though, as it’s often a little too thick.

Reflective insulation is made up of a layer of bubbles sandwiched between single or double foils. They essentially reflect radiant heat rather than absorbing it, but at the same time don’t get too hot in the summer. This makes it a great material to insulate garage doors.

Opting for a new garage door is often the most effective way to insulate your garage. Older doors tend not to have been built with the same insulation technology we have now, whereas new ones are made with materials such as steel and GRP, with options for sectional and roller doors, all of which can enhance insulation.
