Whenever there is a sealing joint needed to be filled, the backer rod is the best way to go. Depending on the specific application and place of installation, there are two major options to consider - closed-cell rod and soft backer rod. For many indoor applications, the soft rod is the best option because of its flexibility and other properties. Conversely, for outdoor applications, the closed-cell rod is a better option.
When it comes to composition, the soft rod is made of foam materials that are breathable which allows easy flow of both water and air. It is also known as the open-cell backer rod that can be used to fit various shapes and sizes of gaps or joints. You can use it to fill gaps that are irregular and those that have different widths. This is all thanks to the softness and versatility of the rod. Hence, this rod is perfect even for narrow gaps.
A soft rod is usually applied for indoor installations in which airtight seals and water resistance are not needed. Since it adheres to both water and air, it works perfectly as a filler prior to applying the caulk material to any joint. As the sealant does not bond to the rod, the bonding only happens between the caulk and the building material.
The key benefits of a soft backer rod are many. Perhaps the most apparent is that it is very easy to install. Due to its great flexibility, the rod can be easily fitted into the joints without the need for so much effort. You can even bend the rod quickly to take the shape of the gap that has to be bridged. This is not possible with the other type of rod that is closed-cell. Ultimately, the use of a soft rod allows you to cover gaps with various widths conveniently and quickly.
