HVAC Curb Materials and Design Standards
Material Selection and Durability Features
HVAC curbs are constructed using various materials including galvanized steel, aluminum, and stainless steel, each offering specific advantages for different applications and environmental conditions. We select materials based on equipment weight, environmental exposure, maintenance preferences, and budget considerations to ensure optimal long-term performance. High-quality curb construction includes corrosion-resistant finishes, reinforced corners, and integrated drainage features that enhance durability and weather protection. Material selection also considers thermal expansion characteristics, structural requirements, and compatibility with existing roof systems and building architecture.
Structural Load Requirements and Engineering
Proper curb design must account for equipment weight, wind loads, snow loads, and seismic requirements specific to Wisconsin building codes and local conditions. We conduct structural analysis to ensure roof systems can safely support HVAC equipment loads and provide appropriate reinforcement when required. Load calculations include equipment operating loads, maintenance access loads, and environmental loads that affect curb performance and building safety. Engineering coordination ensures installations meet all code requirements while optimizing equipment performance and building protection.
Insulation and Thermal Performance
Modern HVAC curb installations include insulation systems that prevent thermal bridging and maintain building envelope performance. We design thermal breaks and insulation details that minimize heat transfer while accommodating structural and weatherproofing requirements. Proper thermal design prevents condensation issues, reduces energy loss, and maintains equipment efficiency in Wisconsin's variable climate conditions. Insulation selection considers fire ratings, moisture resistance, and long-term performance characteristics specific to rooftop applications.
