How to install radiant barrier insulation

It is true that most of the heat that comes into our living space comes through the roof. The radiant barrier is your best option when you want to reduce the cost of the cooling system as well as keep out all that radiant heat that heats up your home. Radiant barrier installation can reduce the temperature of your home for up to 30 degrees.

One easy method of installation is by stapling the radiant barrier under the rafters of the roof. This is capable of reflecting up to 97% of the radiant heat entering the home through the roof. This reduces the number of times you have to use the electric cooling system. It is certainly a great way of cutting down on how much you spend on electric bills.
There is also another way of installing the radiant barrier which is referred to as the secondary method of installation. This method is done by laying the radiant barrier over the attic space instead of stapling it. This method will not lower the temperature of the attic space, however, it will reflect the radiant heat heating its surface. This can also reduce the level of heat transfer from the attic space. This method is a very good compensation for the exposed AC ducts. You can easily lay the radiant barrier over the AC duct to prevent them from the heat.
The only problem with the second method is the fact that it can lead to condensation especially when you’re using the perforated radiant barrier. This condition is common when there are extreme temperature differences between the air above and the air below the barrier. This condition is typical of the winter periods.

Tips On Installing A Radiant Barrier

There are some key important tips to adhere to when installing a radiant barrier. These tips will help shorten the installation time and improve on the quality of your installation.
Tip 1: Start early
Mornings are the best times for installing the radiant barrier. In the morning, the attic space is at its coolest and therefore ideal for the installation.
Tip 2: Move all your tools into the attic space
Ensure to move all the materials you need for installation into the attic space before beginning. This will save you the time of climbing in and out of the attic space.
Tip 3: Keep a reasonable amount of water around
Endeavor to take plenty of water available. Ensure to drink and keep your body hydrated even when you are not thirsty. In the summer, the temperature can become very high as the sun rises.
Tip 4: Carry a backup light
Ensure to carry a backup light especially if your attic space is not well lit. Installing the radiant barrier may even take longer than you expect, therefore, having an alternative light source in case it gets dark is not a bad idea.
Tip 5: Find a good spot to set up your work area
It is ideal to find a central location to set up your workspace. This makes it a lot easier to move between your workspace and your tools.
Tip 6: Watch your steps
Ensure to watch where you put your foot. Some attic floor joists may collapse when you step on them. This is common especially if the joists are not firmly fastened to the attic floor. You do not want to cause a substantial amount of damage to your attic space.
Tip 7: Take a small portion at a time

If you’re installing the radiant barrier yourself, it is very important to take a small portion at a time. Avoid doing it all at once. It will pay you more if you spread out your work over a couple of days. It makes the work easier and you achieve better results. For the professional contractors, it is important to work in groups of twos or threes and split the work into smaller portions for the more effective result. Division of labor is certainly one way to cut down on installation time.
