Backer Rod–An Unseen Essential
In the world of construction, some materials quietly do their job—one such unsung hero is backer rod, a flexible, compressible material made from closed or open cell foam, designed to support and enhance the performance of sealants.
A backer rod is placed as a backing material before caulking or sealant is applied to joints, cracks, or gaps, . Its role is crucial for the following reasons:
Control of Sealant Depth: By placing a backer rod in a joint, it helps ensure that the sealant doesn’t penetrate too deeply. This control is crucial for the proper functioning and durability of the sealant.
Support and Bonding: Backer rods provide a surface for the sealant to adhere to, enhancing its bond and preventing the sealant from sinking into large gaps or joints.
Soft type backer rods provide flexibility and compressibility. They easily conform to various joint shapes, accommodating movement and expansion without compromising the seal. They are available in a range of diameters and lengths, these versatile rods are ideal for a variety of construction applications:
Ideal for Expansion & Contraction Joints: Perfectly suited for managing movement in various construction joints.
Window Frame & Glazing: Provides excellent support and sealing for window installations.
Curtain Wall Construction & Partitions: Ensures stability and proper sealing in large wall structures.
Parking Decks: Enhances durability and performance in multi-level parking structures.
Bridge & Highway Construction: Reliable for heavy-duty applications in roadways and bridges.
Pavement Maintenance: Essential for sealing and maintaining paved surfaces.
Log Home Chinking: Ideal for filling gaps in log homes, ensuring a snug and secure fit.
For each perfectly sealed joint or a flawlessly finished window frame, remember that a soft type backer rod is likely working quietly behind the scenes, ensuring everything stays in place. Go to our Zero Max Silicone Shop to view sizes we offer.
