UniVent ventilation cowls with roofing felt
UniVent for flat roofs in black, powder-coated aluminium and factory-mounted roofing felt (first layer) for mounting on roofs with roofing felt. Flexible roof pitch, 0–5°, to accommodate the roof incline. Dimensions: Ø125 mm or Ø160 mm. The units are available as insulated or as uninsulated with a condensation insert/collar. Slide-in pipe connector included.
The ventilation cowl is optimised against pressure drop and has undergone ventilation-system fireproofing testing pursuant to DS 428.
Ventilation cowls: Aluminium-based components, black powder-coated RAL 9005.
Bottom flange: Stainless steel AISI 304, with integrated SBS (first layer) or APP modified bitumen.
The insulated product variants comply with the fire-safety requirements for insulation, cf. DS 428, and, on the basis of DS 428, fire-safety tests have been carried out on non-insulated product variants. These tests have demonstrated a good fire-safety resistance to a standard fire for up to 60 minutes (cf. DBi ISO 834).
The uninsulated product variants come with a condensation safeguard which reduces the risk of condensation forming due to moist ventilation air.
