Round ventilation duct made of expanded polypropylene (EPP). The most important features of the product are: rigid construction, low weight, easy assembly 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 1 m sections and diameters 160 and 200 mm, wall thickness is 43mm (black colour). Ducts na fittings do not require additional couplings.
