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.
Lenght EPP ducts: 1 m sections
Diameters: 125, 160 and 200 mm.
Wall thickness: 43 mm
Thermal conductivity: 0.039 W / m*K
Airtightness class: ATC2 (old D) @110Pa acc. to PN-EN 17192:2019-01
