Ventilation bends 45˚ made from expanded polypropylene (EPP). Bends are produced in diameters 125, 160 and 200 mm. The standard wall thickness is 15 mm. Each bend has a male-female coupling, the connection method eliminates thermal bridges.
Two 45˚ bends connect easily into one 90˚
Thermal conductivity: 0.039 W / m*K
Airtightness class: ATC2 (old D) @ 200Pa acc. to PN-EN 17192:2019-01
