PVC Invisible Flange Joint (20mm / 4m)

PIR DUCT ACCESSORIES “Seamless, flush connections for PIR pre-insulated ductwork”

Best for: Joining sections of 20mm PIR pre-insulated HVAC duct panels flush together end-to-end. Creating clean, continuous exterior duct surfaces without bulky protruding flanges. Installations requiring high airtightness and the absolute prevention of thermal bridging.

Key Features:

• Designed for 20mm Panels: The double-sided H-profile slot is precisely engineered to securely hold two standard 20mm thick PIR boards together.

• Invisible Flush Finish: Allows panels to sit tightly against each other, hiding the joint internally for a sleek, professional, and flush exterior aesthetic.

• Thermal Bridging Prevention: Manufactured from high-density rigid PVC, which completely eliminates thermal bridging and prevents condensation at the duct joints.

• Airtight Jointing: Ensures a tight seal between duct sections, significantly reducing air leakage and maximizing HVAC system efficiency.

• Easy Fabrication: Standard 4-meter lengths are lightweight and easy to cut, speeding up duct assembly both in the workshop and on-site.
