Garage Door Insulation

What Is Garage Door Insulation?

Like insulation elsewhere in your home, garage door insulation is material that reduces heat or cold transmission, making it harder for hot or cold air to escape or enter your home through your garage, depending upon the weather conditions. If you are trying to make your home an eco-friendly home, as many homeowners are in today’s world, energy-efficient garage doors are a great way to start.

Benefits of Garage Door Insulation

  • Garage Climate Control. As mentioned, insulation prevents heat from escaping from your garage in the winter, meaning it may require less energy to heat your home. By the same token, insulation prevents excess hot air from getting into your garage in the summer, meaning lower cooling costs and no need to worry about walking into a hot garage and hot car every time you want to go somewhere in the summer.

  • Sound Isolation. Good insulation also provides sound isolation in a garage. Your door will make less noise, those who are outside are less likely to hear what you are doing in your garage and you are less likely to be disturbed by sounds from outside while in your garage.

Types of Garage Door Insulation

The two types of insulation you will find in garage doors are polystyrene garage door insulation and polyurethane garage door insulation.

  • Polyurethane Garage Door Insulation: This insulation is a better and denser insulating product than polystyrene. Its strength also adds stiffness to the door, making it more resistant, quieter and less likely to vibrate.
  • Polystyrene Garage Door Insulation: This is an inexpensive, waterproof insulation that comes in a variety of thicknesses. It is a common choice for garage doors because of its affordability and ease of insulation.

Garage Door Insulation Terms

Some of the terms you will want to know when looking at garage door installation include BTU, R-value and U-value.

What Is BTU?

BTU stands for British Thermal Unit, and it is a universally accepted term for the amount of heat necessary to raise the temperature of one pound of water one degree Fahrenheit.

What Is R-Value?

When seeking insulation, you should be looking for a product with a high R-value. R-value represents the ability of a material to slow the transmission of heat.

What Is U-Value?

While you want to look for high R-values, you want to look for low U-values. The U-value represents the amount of heat, in BTU, transmitted through one square foot of material — the door — in one hour at a temperature difference of one degree Fahrenheit from one side to the other. The lower the U-value, the better the insulation.
