The Different Types of Backer Rod and Applications
Introduction
Baker rods, also known as foam rods or expansion joint fillers, are versatile materials used in construction and sealing applications. They serve as a support or backing for sealants, ensuring proper sealant depth and performance. PE baker roads are available in various types, each designed for specific applications. In this article, we will explore the different types and applications of baker rod.
Closed-Cell Polyethylene Backer Rod:
Closed-cell polyethylene PE baker roads are the most commonly used type of backer rod. They are made from a closed-cell foam material that is resistant to moisture, chemicals, and UV rays. These baker rods have a round or cylindrical shape and are available in different diameters to suit various joint sizes.
Application of baker rod:
Window and door frame sealing: Closed-cell polyethylene baker rods are ideal for sealing gaps around window and door frames. They provide insulation, reduce noise transmission, and prevent air and water infiltration.
Expansion joints: These PE baker roads are commonly used in expansion joints in concrete, asphalt, or other rigid surfaces. They absorb movement and allow the sealant to flex without tearing or cracking.
Open-Cell Polyurethane Backer Rod:
Open-cell polyurethane baker rods are made from a soft and flexible foam material. They have a porous structure, allowing air and moisture to pass through. Open-cell baker rods are available in various sizes and shapes, including round, oval, and rectangular.
Application of baker rod:
Window glazing: Open-cell polyurethane baker rods are used in window glazing applications. They provide compressible support for the sealant, helping to achieve the desired sealant depth and preventing over-application.
Soundproofing: These PE baker roads are also used in soundproofing applications. They help reduce noise transmission by filling gaps and preventing sound leakage.
Synthetic Fiber Backer Rod:
Synthetic fiber baker rods are made from non-absorbent, high-density fibers, such as polyester or acrylic. They have a cylindrical shape and are available in various diameters.
application of baker rod:
Construction joints: Synthetic fiber baker rods are commonly used in construction joints, such as wall-to-wall, wall-to-floor, or ceiling-to-wall joints. They provide support to the sealant and prevent three-sided adhesion, allowing for proper movement of the joint.
Curtain wall joints: These baker rods are used in curtain wall systems to maintain a uniform sealant thickness and prevent excessive sealant use. They provide a backstop for the sealant and ensure optimal performance.
Rubber Backer Rod:
Rubber baker rods are made from a durable and resilient rubber material. They have a round or oval shape and are available in various sizes.
Application of baker rod:
Concrete joints: Rubber PE baker roads are commonly used in concrete joints, such as control joints or isolation joints. They provide flexible support for the sealant and help prevent excessive sealant penetration into the joint.
Submerged applications: These baker rods are suitable for submerged applications, such as swimming pools, fountains, or water tanks. They withstand water exposure and provide support for underwater sealants.
Choosing the right type of PE baker road is crucial for achieving effective and long-lasting sealing results. Factors such as joint size, type of sealant, substrate material, and environmental conditions should be considered when selecting the appropriate baker rod.
Conclusion
In conclusion, baker rods play a crucial role in sealing applications by providing support and depth control for sealants. Understanding the different types of PE baker roads and their applications helps ensure proper selection and installation, resulting in effective sealing, improved durability, and reduced maintenance requirements.
