Wind loads create suction and pressure on exterior cladding that must be resisted with properly engineered attachment systems. This article highlights safe and tested solutions.
Overview
In regions exposed to hurricanes or high winds, cladding systems must be engineered to resist uplift and pressure. Backing supports, fasteners, and substrate connections all play a role in resisting wind loads while preserving envelope performance.
Design Considerations
- Follow ASCE 7 wind load tables
- Use stainless steel or corrosion-resistant hardware
- Anchor systems into structural backup—not just sheathing
- Design for rain screen drainage and thermal expansion
🔍 Quick Picks
- Hurricane-Grade Cladding Clip: Knight Wall Systems CI-Girt
- Structural Washer-Head Screws: FastenMaster Panel Fasteners
- Weather-Resistant Flashing Tape: 3M All Weather Flashing Tape
Conclusion
Wind-rated cladding attachments are essential for life safety and envelope performance in coastal and storm-prone areas. Always follow tested assemblies and use hardware proven to resist uplift and corrosion.

Tested Systems and Load Paths
Manufacturers provide tested systems rated for Miami-Dade or ICC-ES protocols, often including both cladding clips and continuous insulation brackets. The complete load path must be engineered from face-mounted cladding, through insulation and brackets, into structural framing. Improper fastener embedment is a top reason for failure in wind uplift events.
