Benefits of Insulating Your Garage Door

Energy Savings 

One of the primary reasons to insulate your garage door is to reduce heat and energy costs. A properly insulated garage door minimizes heat loss during winter and prevents heat gain in summer, helping to maintain a stable indoor temperature. This means your HVAC system won’t have to work as hard, leading to lower energy bills. 

Enhanced Comfort 

Insulating your garage door helps keep the temperature inside your garage more consistent, making it more comfortable to use year-round. This is especially beneficial if you use your garage as a workshop, gym, or additional living space. 

Protection of Stored Items 

Insulated garage doors provide better protection for items stored in the garage. Extreme temperatures can damage vehicles, tools, and other belongings. By maintaining a more stable environment, insulation helps extend the lifespan of your stored items. 

Noise Reduction 

Insulated garage doors can significantly reduce noise from outside, creating a quieter environment inside your home. This is particularly useful if your garage faces a busy street or if you often use noisy equipment inside your garage. 

Increased Durability 

Insulated garage doors tend to be more robust and resistant to dents and damage. The added layer of insulation strengthens the door panels, making them more durable and long-lasting. 

Types of Garage Door Insulation 

Fiberglass Insulation 

Fiberglass is a popular choice for effective garage door insulation due to its affordability, durability, and ease of installation. It comes in pre-formed rolls or loose bundles that can be cut to fit your garage door dimensions. 

Cellulose Insulation 

This type of insulation was made from recycled plant material, cellulose is treated for fire resistance and is easy to install. It comes in a loose form that can be blown into place, making it versatile for different applications. 

Rigid Foam Insulation 

Rigid foam panels offer high R-value and flexibility. They can be cut to fit the dimensions of your garage door and installed on the back of the door panels. Rigid foam is also great for noise reduction. 

Spray Foam Insulation 

Spray foam insulation provides an airtight seal and high R-value. It’s light, fire-resistant, and moisture-resistant. However, it can be challenging to install, so professional installation is recommended

Insulation Panels 

Specifically designed for garage doors, insulation panels can be easily attached to the metal paneling of your door. They provide a quick and efficient way to improve your garage door’s insulation. 

How to Insulate a Garage Door: Step-by-Step Guide 

What You’ll Need: 

  • Insulation material (fiberglass, rigid foam, or insulation panels) 
  • Measuring tape 
  • Utility knife or scissors 
  • Adhesive or double-sided tape 
  • Garage door insulation kit (optional) 
  • Safety gear (gloves, goggles, mask) 

Step 1: Measure Your Garage Door 

Measure the height and width of each garage door panel to determine the amount of insulation material you need. Accurate measurements are crucial for ensuring a proper fit. 

Step 2: Choose Your Insulation Material 

Select the insulation material that best suits your needs and budget. Fiberglass and rigid foam are popular choices due to their effectiveness and ease of installation. 

Step 3: Cut the Insulation 

Cut the insulation material to fit the dimensions of each panel. For rigid foam or fiberglass, use a utility knife or scissors to make precise cuts. 

Step 4: Attach the Insulation 

Secure the insulation to the garage door panels using adhesive or double-sided tape. If you’re using insulation panels, they often come with pre-attached adhesive strips for easy installation. 

Step 5: Seal the Edges 

Ensure that all edges of the insulation are sealed to prevent cold air leaks. This can be done using additional adhesive or weather-stripping

Step 6: Install an Insulation Blanket (Optional) 

For added insulation, you can install a garage door insulation blanket. These blankets provide an extra layer of protection and can be easily attached to the door panels. 

Step 7: Test the Door 

Open and close the garage door to ensure that the insulation does not interfere with its operation. Make any necessary adjustments to ensure smooth functionality.

Mountain View Doors sent a competent and professional technician to fix my garage door. I was able to get same day service at a reasonable cost. Tanner (technician) went over everything that he was going to do and asked if I had any questions. The job was completed with high standards. I highly recommend this company.

Tanner came out and revitalized my old garage door, previously known as "the Beast" but now referred to fondly as "the kitten" due to its pleasant purring sound. This was the best money I've ever spent. The visit was affordable, thorough and amazingly helpful. Tanner pointed out all of the positive aspects of my garage door system, of which I thought there were none, and gave very reasonable estimates of work that is likely to be needed in the future. He also gave me great advice on things I can do to protect and maintain the whole system. I could not be happier and I will always call these guys in the future.

From the process of getting the door ordered, to payment, and getting everything done these folks were great. Bram did a great job! Door works way better than my old one, they cleaned everything up, explained maintenance, and they even took the initiative to get better weather stripping and will be coming back to put that in. These days its always great to have a company that just wants to do the job right the first time. Would use them again without a moment of hesitation.

Aaron was quick to respond and was able to schedule the repair for the same day. Bram communicated well on when he would be arriving and thoroughly explained what repair was needed and how much it would cost. Did the repair and included a tune-up on the door making sure all components were working properly. This is the 3rd time I've used Mountain View Doors, all on different properties, and each time they have been expedient, done great work and pricing has been fair and reasonable. Do not hesitate to contact them for all your garage door needs! A+

Dylan was a great help today! He came and did a simple troubleshooting of our garage issue and reset it without needing to change out anything. He was very knowledgeable of this issue and thoroughly inspected both garage doors before he left. Would highly recommend Mountainview Doors! They installed ours about 6 yrs ago and did a wonderful job!

Tanner did a great job installing two new garage doors for us. He was very friendly and thorough in his explanation of what work he would need to do and what additional options I had with the new doors and system. He took the time to look at some other issues as well to determine if they were something that he could fix. He had the job done pretty quickly, no mess left behind, and took the time to go over all the new features and app to control the doors. Great job overall and very happy with the experience!
Mountain View Doors provided me with excellent service, expertise, and speed of installation when I needed it the most. I had a spring break on me stranding myself without my garage or anyway to open the door and with no additional parking nearby my home. I requested a quote and repair/replacement service at night and within the next morning they called me first thing, provided me with excellent options for repair/replacement, had a technician come out same day and I was able to replace my entire garage door the next day by 4PM at an Extremely good price which included all service and installation and tax compared to whole sale market prices. The door is high quality, met my HOAs color and look guidelines, was installed extremely well and the very friendly and professional technician also was able to answer any questions or concerns I had. They also provide great warranties on service and parts to give customers peace of mind and confidence. If you need fast, affordable help for anything garage related, go no further and give them a call If you need a beautifully done, high-quality, but reasonable costing new door, go no further and give them a call. The have earned my respect and money for the next 10 years!
