All that you need to know about garage door insulation


Insulating your garage door in simple words means keeping your garage warmer, cooler, quieter and protecting your space from external elements.

If energy costs are burning a hole in your pocket, it is time to decide on whether or not you wish to install a good insulation for your garage doors. The garage door is probably the entrance used most frequently to access your home. In that case, every time the door is opened or shut, it can lead to temperature changes inside your garage. If your garage is attached to the rest of the house then it makes sense to insulate your garage door as well in order to avoid temperature fluctuations. Insulating the garage door maybe a good idea to lessen the noise level if your garage is attached to the rest of your living space.

The purpose of garage door insulation

In regions where the natural elements are extreme, like excess heat, cold or windy weather, it makes sense to have an insulated garage door. But if your garage is just a place to park your car or used as storage for your other belongings, insulated garage doors may not be a necessity. It makes sense to look at other viable options.

Wherever insulation is required for a garage door, it is lined with insulation in order to slow down or reduces the conduction of heat or cold from outside and vice versa. Insulation acts as a barrier to the heat flow keeping your garage warm in winter and cool in the summer months.

There are several choices available in the market today. The broad categories are:

Batt insulation

This is a fiber glass material. It is relatively easy to use. This is a flexible insulation stuffed into exterior walls and uses paper or foil as back up. This enables the batt insulated doors to have vapour and air barriers. The batt insulation is usually considered economical and cost effective.

Reflective Insulation

The solid and rigid boards of reflective insulation has aluminium foil applied to one or both sides of the insulation materials. This type of insulation reflects heat and hence is a good choice for garages facing extreme weather conditions.

Polystyrene Foam

This type of foam insulation is sold in large sheets which need to be cut according to the panels and attached to your garage doors in individual sections. This is water proof and comes in various thicknesses. The installation process is simple. This is a good value for money option.

Polyurethane Foam

This has comparatively more density and is a better insulator. The installation process remains similar to the polystyrene foam. It is directly bonded to the garage door. This makes it more resistant and is a quieter option when opening and closing the garage door.

Points to be noted when you install garage door insulation

Decide on your budget. Check if the insulation is compatible to your garage door. Keep in mind whether your garage door can bear the weight of the insulation. Further, check for fire proofing, water proofing and other aspects of the material. You also need to check whether the doors’ springs need to rebalance after the installation. Once the installation is complete check if a proper sealing has been done. Check for gaps and weather proof the garage door which also provides access to the insides of your house. Take a close look at all electrical outlets for any leaks. This could save you on unnecessary energy costs.

However, one also needs to keep in mind that the garage door insulation is effective and efficient depending on whether the rest of your garage is insulated or not.

Further, functionality and performance of your garage door after insulation is an important factor to be considered before deciding whether the insulation was worthwhile or not. Insulated doors maybe more sturdy than non-insulated doors.


One needs to know that insulation by itself does not generate heat or cold. Insulation only traps the air and safeguards your garage space from all weather extremities.
