Garage Door Insulation Kit Buying Guide
Many people spend a lot of time in their garages, whether that is working on a car to using it as a gym. However, the garage is one place with the least-efficient use of energy since the garage door is made of wood, aluminum or steel.
They are usually uninsulated, which during summer or winter, temperature levels in the garage can reach both extremes. Investing into a garage door insulation kit will prevent this from happening and improve the efficiency of your home.
To help you make an informed buying decision, we have produced the below guide regarding DIY garage door insulation kits.
Steps to Install Garage Door Insulation
Installing an insulation kit to your garage door is not as hard as you would think. It can be completed by yourself but having another person to help does make things much easier. Below are some steps that you to follow in order to achieve a simple and stress free installation.
Preparing the Surface
As you are preparing the inside of the garage door, there is no need to worry about the state of the garage door facing outwards. However, installation of an insulator needs adhesive which requires a clean surface to stick to, thus cleaning of garage doors is vital.
To ensure that the garage door is completely clean, you can use either acetone or a degreaser and later wiping it down with warm water. Once it dries up, you can then apply the adhesive.
Application of the Adhesive
Double sided tape is a popular choice for a strong adhesive and most kits comes with multiple Velcro adhesive squares too. For tab installations, you should follow the instructions on the manual because the application of adhesive tabs is the most time-consuming of the whole process.
The next step is removing the protective covers from the tabs and sticking them to the door. You can then follow up by removing the second protective cover from the adhesive part in contact with the barrier.
Test Fit Some Panels
Before removing the outer protective adhesive casings, test to see if the panels fit. Carry out a test install before the adhesive sticks to the panels because this will enable you to determine which panels need adjustment to fit perfectly.
Trimming of the Panels
Overlaps on the edges of the barrier’s insulation is not a bad thing but can be useful in ensuring the garage door insulation is held in place. You should measure the panels, adding several inches before carefully cutting. It is more useful to expose the adhesive top rows before installing the top of the installation.
Subsequently, this is followed up by cutting the panels to leave a few inches at the bottom to wrap into the panel supports of the garage door.
Installation of Radiant Barrier Insulation Panels
Exposing the top row of adhesives and following that up with installing a panel at the topmost portion enables you to stretch the material before pushing it onto adhesive tabs. It eliminates any wrinkles from showing after installation is complete.
Once the top part is in position, the panel’s lower part is removed out of the way exposing the adhesive on the remaining tabs below. It is followed by stretching the lower portion into place and application of pressure on the adhesive squares to ensure they properly stick.
Types of Garage Door Insulation
The various insulation kits come with different properties, differentiated by thickness, durability levels, shapes, cost per size, different life spans and other factors depending on your needs. Below are the three most common types of garage door insulation.
This insulator is sold on rolls and usually has a thickness of about an inch and a half. Purchasing the reflective foil can either be a single file or double file, depending on your requirements.
In between the two aluminum foils is a layer of polyethylene foam, with double foil insulation coming with two coats of this foam. Despite not being aesthetically pleasing, the reflective foil is a very useful insulator especially for regions with hot climates as it is reflecting the radiant heat. Furthermore, its R-value ranges from 3.5 to 6 but this depends on how you apply it.
Usually sold in large sheets, polystyrene foam needs to be cut to a size equivalent to that of the garage door. This material is very rigid and provides high insulating values despite being of relatively little thickness. Furthermore, the material is more robust to work with in comparison to reflective foil and offers better insulation.
For those who value aesthetics, panel kits is the best garage insulation to go for and are easier to install. They are made of plastic laminated polystyrene or fiberglass and the kit comes with pre-cut panels that comfortably fit into the channels of the garage door frame.
Polystyrene offers better insulation in comparison to fiberglass, but fiberglass is more resistant to mold and water. Installation of both these panels is fairly simple with both taking around an hour to install.
Factors to Consider when Choosing Insulator
Not all garage door insulation kits are the same and many can be fairly expensive. For that reason, its essential that you understand the basic factors to consider and what to look out for in order to get the best value for your money.
Effectiveness of Insulator
All garage door insulation comes with a R-value rating system. It is a system that measures how effective the insulation is at insulating the garage door. Insulation with a higher R-value will provide better insulating properties.
Depending upon whether you plan to fit the garage door insulation yourself or not, you may have to budget in the installation. The installation is fairly easy but it is understandable that not everyone has the time to do it themselves.
The Weight of the Insulator
For those that use an electric garage door opener, the added weight of the insulator may slow down and cause additional stress to the opener mechanism. If this is the case, you may want to look into upgrading the opener before adding additional weight to the door. However, most openers can handle a little more weight on the door from the insulation.
Research your Garage Door
Not all garage doors are the same and you may not require that much garage door insulation. However, if the door has no insulation or padding whatsoever, you will want a complete kit that can be installed fairly easily.
Insulation for your metal garage door should be an essential. It will keep the heat inside the garage during the cold winter months and the heat out during the summer. This instantly boosts the efficiency and will pay for itself when you factor in wasted energy costs.
All the recommendations in this article are affordable and suit the majority of garage doors from single to double and even custom sizes. We advise that you take your time with your measurements before choosing a garage door insulation kit. The last thing you would want are panels that are too small or those that require lots of trimming.
We also recommend spraying garage door lubrication within any of the moving parts that will be covered up by the insulation. This saves time removing the insulation in case there are any problems in the future.
