Benefits of Insulating a Garage Door

1. Prevents Air Leakage & Saves Energy

Air leaks and holes in the garage cause high energy consumption by the HVAC system. Garage door insulation helps maintain a conducive temperature by preventing air leaks through the door, saving the energy consumed by your HVAC system. 

During winter, insulated garage doors prevent cold air from seeping through the door and entering the garage. 

2. Increase Door Strength

Insulated garage doors are stronger and more durable than uninsulated garage doors. Insulated garage doors are made up of multiple layers, there is a layer of insulation in between two layers of hard materials like steel. 

Unlike uninsulated garage doors that are made up of a single layer of hard material, insulated garage doors hold less heat and can withstand external impact more than uninsulated garage doors.

3. Reduces Street Noise

One significant advantage of insulation is that it dampens the noise coming from your surrounding environment. Insulated doors are tightly constructed and do not make rattling sounds like other doors.

4. Helps to Protect Your Car And Belongings

Cold weather conditions affect car battery performance and cause low pressure in tires. Garage door insulation prevents the garage from becoming really cold. Also, cars or belongings that are stored in the garage are protected from theft.

Radiant barrier insulation is made up of two layers of reflective materials, like aluminum, and another layer of air space. The function of the layer of air space is to trap the warm air in the garage from going out.

Unlike other forms of insulation, radiant barrier insulation does not slow down the convection process, so it does not have an R-value.

4. Cellulose Garage Door Insulation
