PIR Aluminum Panel

(1.)High flame retardant grade: High-quality polyurethane duct panels, especially the PIR type, through formula optimization and the addition of flame retardants, can meet the B1 grade (difficult-to-burn material) stipulated in the national standard GB8624-2012 or even higher fire resistance grades (such as the European standard B-s1, d0).

(2.)Low smoke and non-toxic: When exposed to fire and burning, high-quality products can effectively suppress the spread of flames and significantly reduce the generation of smoke and toxic gases (meeting relevant low smoke and non-toxic standards), buying precious time for personnel evacuation and fire rescue, and enhancing the fire safety level of buildings.

(1.)Integrated molding: The sheet material itself serves as both the structural layer and the insulation layer of the air duct, eliminating the cumbersome subsequent process of wrapping insulation materials around traditional metal air ducts (such as attaching insulation cotton, wrapping aluminum foil, etc.).

(2.)Special connection method: With a unique "T" -shaped or "Ω" -shaped flange design, combined with special adhesives (such as polyurethane glue) and inner and outer corner guards/I-shaped inserts, it can achieve rapid and precise splicing and sealing of air ducts. This "flangeless" connection method significantly increases the construction speed and shortens the project period.

(3.)Easy processing: The sheet material can be easily cut and grooved (V-shaped or U-shaped grooves) with special tools, facilitating on-site bending into shape (rectangular or circular air ducts) and the production of various pipe fittings (elbows, tees, reducers, etc.) as needed, with high flexibility.
