Why Should You Insulate Your Garage Door?
Insulating your garage door prevents any heat loss from outside to your garage. Consequently, without proper insulation, your garage doors made out of metals will easily catch the temperature from outside.
Some reasons to insulate a garage door include:
-For attached garages
-For garage doors that are under living rooms
-Gym rooms or workshops
-Areas with extremely hot or cold weather
Advantages of Insulating Garage Doors
Energy Saving
The primary reason why homeowners insulate their garage doors is because of energy bills savings.
Insulation reduces pressure on your HVAC system by regulating temperature around your wall and rooms close to it.
The U.S. Department of Energy reports that sealing gaps and adding insulation increases energy efficiency within a house. For further tips on saving energy, refer to the U.S. Department of Energy Insulation Guide.
Improved Indoor Environment
Insulating your garage will result in an increased level of comfort throughout the year, which is very important if you use your garage as:
-A work place
-A gym
-A laundry room
-Storage facility
Noise Reduction
The insulation of garage doors helps to minimize vibrations and any external noises.
Along with proper maintenance and efficient functioning, such an insulation can assist in creating less noisy movements of your garage door. People who face noisy operation of their garage doors can even avail the services of Garage Door Repair.
Increased Durability
Certain types of insulation make the door more rigid which helps reduce vibration and damage over time.
The best way to insulate a garage door depends on:
-Climate
-Budget
-Type of garage door
-Desired insulation performance
Garage Door Insulation Materials
| Material | Best For | Advantages | Drawbacks |
| Foam Board Panels | Most homes | Lightweight, high R-value | Requires cutting |
| Reflective Foil | Hot climates | Reflects radiant heat | Lower cold-weather performance |
| Fiberglass Batt | Detached garages | Affordable | Can sag or absorb moisture |
| Spray Foam | Professional projects | Excellent sealing | More expensive |
Foam Board Insulation
The most effective type of insulation used on garage doors is foam board. It is also an effective type of insulation material for sectional garage doors.
Advantages include:
-High R-value
-Water resistant
-Low weight
-Simple to install
Common materials include:
-Polystyrene
-Polyisocyanurate (Polyiso)
Reflective Insulation
Reflective insulation works better in places with hot weather since radiant heat is the major concern there.
This type of insulation prevents sunlight from entering the garage and helps prevent the accumulation of heat within it.
Fiberglass Insulation
Fiberglass insulation is affordable but heavier compared to foam board insulation.
The increased weight can affect:
-Garage door balance
-Performance of the opener
-Tension of the springs
Hence, if you have a hard time opening your garage door, it is advised that you schedule a Garage Door Safety Inspection prior to the installation of fiberglass insulation.
How to Insulate a Garage Door Step by Step
Most of the time, insulating your garage door isn’t difficult even with homeowners who have DIY skills. Nevertheless, stay away from the springs, cables, and tracks since they are under high tension and may lead to serious injury.
Things You Will Need
-Foam board insulation sheets
-Tape measure
-Utility knife
-Ruler
-Insulation adhesive/retention clips
-Weather stripping
-Gloves
-Safety goggles
Step 1: Measuring Garage Door Panels
You should keep in mind that correct measurement guarantees perfect fitting of insulation.
Therefore, it is necessary to take into consideration:
-width of the panels
-height
-recess depth
Step 2: Cutting Insulation Panels
Use a utility knife with a straight edge for cutting insulation panels accurately.
Insulation needs to be fitted perfectly in the garage door panels.
Step 3: Installing Insulation
It is important to remember as a homeowner that you need to keep your garage door from being overburdened by installing insulation.
It is crucial to install insulation by applying:
-retention clips
-adhesive
-retainer channels
Step 4: Sealing Air Leaks from the Garage Door
No matter how well insulated your garage door is, it becomes less efficient because of air leakage. That is why a Professional Maintenance Services can help check for seals that have gotten old, misalignment, and balance that affect energy efficiency.
Be aware that the items that need replacing include:
-Bottom seals
-Side weather-stripping
-Top seals
Step 5: Checking Door Functioning
Open and close the door a few times after installing it.
It is important to remember that one should not try adjusting the garage door torsion springs as homeowners and professional garage door mechanics advise against this action because of the danger of getting injured during such work because of the high pressure in the springs.
Therefore, pay attention to:
-Inconsistent functioning
-Straining noise
-Slow closing
-Problems with balance
Insulation of a Garage Door – Will It Save You from Higher Energy Costs?
Certainly, the insulating of the garage door will help you cut down costs associated with electricity bills, especially if you own a connected garage.
The reasons include:
-Separating any leaks of air
-The adjoining property of a garage to the house
-Climatically regulated rooms neighboring the garage
Realistic Cost Savings through the Insulation of the Garage
One is most likely to experience:
-Stabilization of room temperature
-Increased efficiency of HVAC systems
-Comfort in rooms adjacent to the garage
Nevertheless, despite the insulation of the garage door, climate control of the garage itself hasn’t been ensured.
For overall assistance regarding air sealing and insulation performance, check the Environmental Protection Agency’s ENERGY STAR Home Sealing Guide.
