There are three basic types of backer rod. The open-cell type is most common, but there are also closed-cell backer rods. These rods are easier to compress and provide more surface area for the sealant to adhere to. However, closed-cell backer rods tend to have a higher moisture absorption capacity. For high-moisture-retention joints, closed-cell products are often recommended. Closed cell backer rods have the highest adhesion capacity, while closed-cell backers tend to adhere to the sealant better than open-cell products.
Another type of backer rod is FillPro(tm). It is composed of polyethylene foam and is chemically inert. It will not stain, adhere to, or cause damage to sealants. It is compatible with virtually all sealants. It is especially compatible with rubber asphalt and silicone. The backer rod is incredibly flexible and can be used in a variety of applications. If you are looking for a quality backer rod, FillPro is the way to go.
When looking for backer rod, it's important to consider its thickness. While an open-cell backer rod is less dense, it is more flexible. Open-cell rod is more suitable for indoor use because it is less likely to absorb moisture, while closed-cell backer rods are made of more dense material. Both types of backer rods are available in a variety of diameters. They are compatible with most types of cold-applied sealants.
A standard backer rod is made of compressible foam that creates a backstop for sealing tools. It is widely used in glazing operations, window and door applications, curtain wall joints, log constructions, and other construction applications. A backer rod has several benefits, including speeding up the curing process and improving the durability of the building materials. Once installed, it will be the foundation for your new home's construction. When used in conjunction with a vapor barrier, backer rod will make the process go more smoothly.
When choosing the material for backer rod, size is an important factor. It is generally recommended to choose a rod that is one-half inch bigger than the width of the joint. It should be inserted at least 1/2-inch deep into the joint. Using a blunt edge tool, a backer rod can be twisted into place. If the rod is too big, it won't fit into the joint. In this case, a smaller backer rod might be used.
