The right cladding support system spacing starts with understanding what your project demands. Every adjustment to a wall assembly changes the demands placed on the cladding support system. That’s why support system spacing isn’t selected from a standard detail. It’s engineered around the unique conditions of the project. Here are just a few of the variables that can influence support spacing: Heavier cladding materials create greater downward forces, often requiring brackets, rails, and girts to be spaced closer together to safely transfer loads back to the structure. Higher wind and seismic loads depending on building height, location, and exposure all influence the forces acting on the support system, often requiring spacing adjustments to meet project-specific loading requirements. Thicker continuous insulation moves the cladding farther away from the structural wall, increasing the forces acting on the brackets and connections and changing how the system is engineered. Different backup wall materials provide different fastener capacities. A concrete wall behaves differently than steel studs or CMU, directly influencing how attachment loads can be distributed. Different cladding materials have unique spanning capabilities. Fiber cement, metal panels, terracotta, and other façade materials each have their own support requirements to help control deflection and maintain long-term performance. None of these variables exist in isolation. If you change one, then the support strategy may need to change with it. Knight Wall Systems project-specific engineering is about designing a cladding support system that balances structural performance, thermal efficiency, constructability, and your design intent from the very beginning. If you’re evaluating a new façade system, involve our engineering team early. We’ll help develop a support strategy that’s tailored to your project.
