The closed cell backer rods are harder and firmer when it comes to bending compared to the open cell rods. This is why they are more difficult to install. These rigid rods are ideal for outdoor applications whereby the environment is considered to be harsh. They can easily repel moisture and offer the stable finish on the opening. The types of backer rods that are used by contractors are usually determined by the type of operations that they are involved in. In addition to that, the size of the gap is also an important factor that has to be considered. Joints that are a few inches wide can be sealed easily with the closed cell types. The larger joints can be sealed with the open cell rods. The rods are used to ensure that the building material have room for expansion and bending. This keeps the structure in good condition. It is highly recommended that the sealants used to be flexible throughout their lifespan. This will ensure that they withstand the dynamic environment.
Backer rods are needed when it comes to filling gaps that exist between different construction surfaces before the application of caulk, which seals the joint completely. Majority of the contractors use this item in tiling and flooring whereas some use it in window sealing, surface counters and wall paneling. They are used to ensure that the perfect surface finish is achieved. There are two main types of backer rods that are available in the market, that is, the closed cell and the open cell rods. The open cell rods are the best to use for indoor applications because their moisture content is usually low. The closed cell rods on the other hand are ideal for use in outdoor environments. They are more effective where there is need for waterproofing and insulation. These two types of rods are required in most construction sites to ensure that firmness, good appearance and durability is achieved. The open cell rod is composed of airy breathable material that is slightly denser than the material used for closed cell rod. The airy nature of the open cell rod makes its installation easy. It is preferred because of its soft and flexible nature. In cases where the size of the gap is not constant, the open cell rod is the best choice since it can be compressed to fit in perfectly. This is what makes it universal compared to the other type.
