90 ̊ ventilation bend made of expanded polypropylene (EPP). Bends are produced in diameters 125 and 150mm. The standard wall thickness is 15mm (gray). Each bend is delivered with one female coupling in the set, the connection method eliminates thermal bridges. The 90 ̊ bend can be cut in half along the extrusion, forming two 45 ̊ bends.
Thermal conductivity: 0.039 W / m * K
A/irtightness class: C
Surface roughness: 0.077 mm
