Dry joint systems also help with thermal movement and building shifts.
Tip: Proper joint geometry is crucial for sealant performance. You should follow the right joint shape for each system.
You can use both wet joint systems and dry joint systems in one project. This mix gives you the best of both connection methods. You get strong weatherproofing and easy modular assembly. You must check joints often to keep your building safe. Joints play a big role in the look and life of your aluminum panel system. You should always plan your joints before you start your project.
Joints, Fasteners, and Code Compliance in Aluminum Panel Systems
Joint Designs for Movement and Weatherproofing
You need joints that help your aluminum panel system handle movement and keep water out. Joints let panels expand and contract as temperatures change. This movement protects the panels from cracking and keeps the building envelope strong. You see movement joints in curtain walls, metal panels, and stone cladding. These joints allow the cladding and structure to move differently without causing damage.
You can use joint fillers in many sizes and colors to match your project. Wet sealed joints use a backer rod and sealant to block moisture. Dry joints rely on mechanical parts for weatherproofing. You must design joints to manage wind, rain, and thermal movement. The roof system’s line of fixity sits at the low eave, so panels expand toward the ridge. Fixed joints need enough fasteners and a cinch plate to resist gravity and thermal forces. The cinch plate increases the strength of the panel material and compresses the sealant for a tight fit.
Tip: Well-designed joints improve durability and help you meet code compliance. You protect your building from leaks and keep the panels secure.
Fastener Types, Corrosion Prevention, and Durability
You need fasteners that hold panels tightly and keep your building safe. Fasteners come in many types, such as screws, bolts, rivets, and clips. Aluminum and aluminum alloys are common choices because they are light and resist corrosion. You can also use stainless steel, brass, or Monel fasteners for extra protection in harsh environments.
You must select fasteners that match the panel material and the building’s needs. Stainless steel fasteners prevent rust and increase durability. Brass and Monel fasteners work well in coastal or industrial areas. The right fastener keeps panels strong and stable for years. You must install fasteners correctly to avoid loose panels and water leaks.
| Fastener Material | Properties | Best Use Cases |
|---|---|---|
| Aluminum | Lightweight, corrosion-resistant | Standard environments |
| Stainless Steel | High strength, rust-proof | Harsh or wet environments |
