Everything you need to know about insulated garage doors

Insulated Garage Door, Property insulation

You may think it odd to be thinking about insulated garage doors – after all, most people use their garages for their car or to store things they don’t need but don’t want to throw away! So why do you need to keep them warm?

Is your garage attached to your house?

If your garage is attached to your property, then it’s extremely important to insulate it as much as possible, and that includes fitting insulated garage doors. Your garage is part of your house and the colder it is, the more likely it will be to draw the heat away from your living areas and allow it to escape through any gaps in the doors. Not only will that make your house cooler, it’ll also mean bigger heating bills. A properly insulated garage will keep the cold out and the heat where it belongs – inside!

Additional advantages of an insulated garage door are that it will help keep your garage and house cooler in the summer, and also give you greater sound insulation.

Why protect your car and tools?

If you use the garage to park your car in, keep your tools or store things, insulated garage doors will help protect them all from potential damage because of the cold. By investing in a new insulated door that fits the space perfectly, you’ll also be protecting against rain damage – any gaps between the door and the wall will let in water, as well as allowing space for insects and mice to squeeze through with the consequent damage they could potentially do.

Insulation is also important in garages if you store a fridge or freezer in yours. In the hot weather, the door’s insulation will help to keep the garage cooler, which in turn will mean that the fridge or freezer won’t have to work so hard to keep your food at the correct temperature. This will not only save on electricity bills, it’ll also lengthen the lifespan of your equipment.

Added strength

Another advantage of insulated garage doors is that they’re stronger, meaning they offer increased security protection for you and your home.

The best doors for warmth

Sectional garage doors are the best ones to choose if insulating your garage is your top priority. The insulation is enclosed within the thick panels – where the panels are joined, there is no insulation, which means there’s more chance of heat being able to escape from the non-insulated areas.

The slats in roller doors are also insulated, but the number of slats means the insulation is less effective than a sectional door. Up and over doors and side-hinged doors can be insulated and if your doors are made of wood, that’s a pretty good insulation in itself. However, the way these doors are fitted are more likely to allow drafts in and the warmth out.

What’s your R-value?

In 2020, the R number has different connotations, but when it comes to measuring your garage insulation, the industry standard measurement is thermal resistance, also known as the R-value. Click here for more information and find out how to work out how effective your garage is.
