Everything You Need to Know About Garage Door Insulation

Garage Door Insulation

If you’re in the market for a new garage door, insulation is an important factor to consider. Different types of insulation offer various benefits and drawbacks, so it’s important to know what type of insulation will work best for you and your family. Let’s take a closer look at the different types of garage door insulation available and what each offers. 

Garage Door Insulation

Polystyrene Foam Insulation 

Polystyrene foam is one of the most common forms of insulation used in modern garages. It is lightweight and easy to install, making it an ideal choice for many homeowners. Polystyrene foam also provides excellent energy efficiency, which can help keep your heating and cooling costs down. The downside is that polystyrene foam does not have great soundproofing qualities, so it may not be the best option if noise from outside sources is a concern. 

Polyurethane Foam Insulation 

Polyurethane foam is an increasingly popular form of insulation due to its superior soundproofing abilities. This type of foam has great thermal characteristics as well, allowing it to keep your garage warm in cold weather and cool in hot weather. The downside is that polyurethane foam can be expensive and difficult to install correctly, making it more suitable for experienced DIYers or professional contractors.  

Fiberglass Insulation 

Fiberglass insulation has been around for decades and remains one of the most affordable options on the market today. This type of insulation offers good thermal protection while providing decent soundproofing abilities. The main downside with fiberglass insulation is that it can be prone to settling over time, meaning you may need to replace or add additional material after some years depending on how much settling occurs. 


No matter which type of garage door insulation you choose, make sure you understand all the pros and cons before deciding. Each kind offers unique benefits along with potential drawbacks, so do your research before committing to any one type! Ultimately, choosing an insulated garage door will provide numerous benefits for both energy savings purposes as well as noise reduction—so no matter which type you choose, you won’t regret investing in quality garage door insulation.
