We are pleased to introduce our advanced method for assembling PIR (polyisocyanurate) duct panels with galvanized iron (GI) facing (PIR Duct Panels with GI Facing) into high-performance HVAC ductwork. This assembly process ensures that the ducts not only provide superior insulation and durability but are also easy to install and maintain.
Step-by-Step Duct Assembly Process
1. Cutting and Preparation
The assembly process begins with the precise cutting of PIR duct boards to the required dimensions for each project. GFI PIR Panels are then processed by cutting both edges at a 45-degree angle, allowing them to be folded into a perfect 90-degree corner. Alternatively, the panels can be cut with two edges at 90 degrees, which can then be securely fastened together using screws for a strong and seamless joint. For PIR Duct Panels with GI Facing, when cutting the edges, leave a little extra panels on one side and remove the foam, then fold it, and finally fix it with rivets, as below viedo. This process ensures that the ductwork is both durable and easy to assemble.
2. Joining PID Panels with Flanges
Once cut, the edges of the Pre-insulated Duct Panels are joined by PVC or Aluminum flanges. They are fitted to the ends of the panels, creating a sturdy framework that ensures stability and rigidity. Proper alignment during this stage is critical to achieving a tight seal, which minimizes air leakage and maintains system efficiency.
3. Applying Adhesive and Sealing
After the flanges are in place, a high-quality adhesive is applied along the seams where the PIR panels meet. This adhesive strengthens the joint, ensuring a long-lasting bond between the panels. To enhance airtightness, specialized sealants are applied to all joints and edges, providing additional protection against air and moisture leakage.
4. Securing with Screws and Hooks
For added stability, screws or hooks are used to fasten the Air Duct Panels and flanges together securely. These fasteners ensure the panels stay firmly in place, even under high-pressure air flow. Hooks are also used to hang the assembled duct sections, ensuring proper positioning within the HVAC system.
5. Final Inspection and Testing
Before the HVAC ductwork is considered complete, a thorough inspection is conducted to ensure all connections are secure, and there are no gaps or leaks.
