Ventilation bends 45˚ made from expanded polypropylene (EPP). Bends are produced in diameters 125, 160 and 200 mm. The standard wall thickness is 43mm (black colour). The connection method eliminates thermal bridges, no additional couplings are required.
To create a 90° bend two 45° beds can be connected together.
Thermal conductivity: 0.039 W / m*K
Airtightness class: ATC2 (old D) @ 200 Pa acc. to PN-EN 17192:2019-01
