Round ventilation duct made of expanded polypropylene (EPP)

Round ventilation duct made of expanded polypropylene
(EPP). The most important features of the product are: rigid
construction, low weight, easy assembly (female coupling
on each element) and good thermal insulation. EPP ducts,
used, for example, as sections of the supply and exhaust
ventilation systems with heat recovery, do not require
additional insulation. The system eliminates the formation
of thermal bridges.
EPP ducts are manufactured in 0.5 m and 1 m sections and
diameters 125, 150, 160 and 180 mm. The standard wall
thickness is 15mm (gray colour). Available on request 43mm
thick (black colour). The duct is supplied with one female
coupling in the set.
