Garage Door Insulation Kit – Buyer’s Guide

For people who are looking to insulate their single or double car garage doors to make their work spaces more comfortable, you need a reflective insulation kit. When buying it, you should consider its reflective value, material used, weight, and its number of panels. You should also check whether the panels are pre-cut and consider their size.

Type of insulation used

  • Reflective Foils
    The reflective foils are sold in rolls and they create air pockets that in turn regulate the temperature in the insulated room. Most reflective insulation kits feature an R6 value. This ensures that the thermal performance is maintained at the top. However, you need to consider the quality of the adhesives because they will determine how durable the installation will be. The reflective foils are the cheapest type of insulations.
  • Foam
    The foam insulation is mostly obtained from polystyene. The foam insulations are designed as large panels or some sheets. These panels are precut so they can fit the parts of the door just as it is designed. The foam insulations have a reflective value higher than that of the reflective foams.
  • DIY Foam Kit
    Like the foam insulation, the DIY foam kit comes with precut panels. Their reflective value is the best of the three types. If they do not fit the garage door as per its dimensions, you can trim them for a great fit. The DIY foam is easier to install because it normally takes less than one hour.

Weight

When choosing insulation for garage doors, many people ignore its weight. If the insulation material is too heavy, it can affect the balance and stability of the garage door opening. This will force you to adjust the spring so that it adequately supports the door.

R-value

R-value (reflective value) refers to the measure of thermal resistance. It is the transfer of heat from one point to another. Normally, the heat is from a hot area to a cold one. The efficiency of the insulation kit is determined by the R-value it has. The higher the reflective value, the better the performance of the insulation kit.

The R-value of a garage door insulation kit is influenced by its thickness and density. So, when you go shopping for an insulation kit, make sure to look for the highest reflective value possible.

How Can I Insulate My Garage Door?

You will find some insulation kits with instructions but others don’t. If there is no guideline, please follow these steps:

  1. Obtain the gear you need to insulate the garage door. These include the insulation kit that will fit appropriately on the garage door. As such, you also need a measuring tape to take the required dimensions and a knife that is sharp to make clean cuts.
  2. Measure how wide and tall the garage door is. You need to consider whether the door is wooden or metal. Ensure to cut the panels in the correct measurements and add some extra inches so the door is covered all round. The sheet should be free of holes so there is no heat getting through or out of the garage. Otherwise, the insulation process would be wasted.
  3. Repeat the above steps until all the parts of the garage door are insulated. The final results should be a soundproof, waterproof, and stylish garage door. If it is fully insulated, you will feel the difference in the climate in your garage. During summer, the room should feel cooler while during winter the garage should feel warmer.

What are the benefits of using an insulation kit?

When your garage door is insulated, your home will be more energy efficient than ever. This is because during the winter, for instance, you will not need to use electricity or other source of energy to power the heater. This means that your utility bills will be lower so you can spend your money otherwise. This will help reduce your carbon footprint so you can contribute in the conservation of the environment.

The main benefit that drives the use of insulation kits is their ability to create a microclimate despite the hot or cold weather outside. The aim is to make the environment around the garage as comfortable as possible.

Conclusion

Garage door insulation kits are a great way for you to improve the efficiency in your garage. Your workshop will be more comfortable since the environment will be more conducive than ever. You no longer have to deal with high or low temperatures when you can create an insulated room easily.

When buying the insulation kit, you should decide on the type of insulation you want it to have. We hope that our buying guide will help you pick the most effective insulation kit based on your needs and as per the benefits of each.

You should also look out for the weight of the kit since the lighter it is, the easier it is to handle. What’s more, if the material is too heavy, it will reduce the efficiency of the insulation because the door will lose its balance.
