pir pre-insulated air duct panel

Insulated PIR panel 1)Thermal conductivity:0.018w/m.k 2)Density:50kg/m3 3)Cell closed rate:96% 4)Fast delivery pir pre-insulated air duct panel YOUSHI Insulated PIR panel is the improvement of Polyurethane (PU) panel.The datas for PIR and PU is as below:Polyurethane(PU) air duct panel coated with both sides alu foil1) Density: 40-45 kg/m3 2) Thermal conductivity: 0.021W/mK 3) Compressing strength: 0.2MPa 4) Bending strength: 1.0Mpa 5) Flame retardant: Class B1 6) Water absorption: 1.9% 8) Dimension change: 0.3% 9) Working temperature: -100° C to +80 ° C 10) Dimensions: 3, 900 x 1, 200 x 20mm 11) max allowed wind velocity: ≤ 12 m/s Polyisocyanurate(PIR) air duct panel coated with both sides alu foil1) Density: 50kg/m3 2) Thermal conductivity: 0.018W/mK 3) Compressing strength: 0.2MPa 4) Bending strength: 1.0Mpa 5) Flame retardant: Class B16) Water absorption: 1.9% 7) Max. Smoke density: 2% 8) Dimension change: 0.3% 9) Working temperature: -260 ° C to +190° C 10) Dimensions: 3, 900 x 1, 200 x 20mm 11) max allowed wind velocity: ≤ 12 m/s.Insulated PIR and PU panel are simple and easy but highly productive fabrication and installation Easy maintenance and modification can be performed on site, cut and gluing can be applied in any section of the ducts. Excellent appearance and long lasting, life expectancy are 20 years
