Princi Aluminum Pre-Insulated Ducts

PIB

Aluminum pre-insulated ducts, for heating, ventilation and air conditioning air distribution systems.

Advantages

  • Long duration granted by the characteristics of the aluminum foil (absolutely no rust or other type of deteriorations)
  • No fibers release or dispersion
  • Very high thermal insulation
  • Outdoor installation without any additional protection
  • Excellent air tightness
  • Resistant to high pressure of the air (positive and negative)
  • Resistant to salty atmosphere
  • Easy access for maintenance
  • Easy cleaning (water washing, brushing or disinfection)

Application

Realisation of HVAC air distribution systems (supply, return, exhaust, fresh air) to be installed indoor and outdoor, especially in the following projects:

  • Hospitals and operating suites
  • Clean rooms and pharmaceutical industry
  • Food industry
  • Shopping malls/centres
  • Swimming pools

Fabrication

Our air ducts are fabricated using a rigid polyurethane foam board, faced on both side by an aluminum foil.

  • Panel thickness: 21mm, 25mm, 30mm, 42mm and 64mm
  • Rigid polyurethane foam, closed cells, density 48kg/m3 without CFC-HCFC-HFC
  • Internal facing: Aluminum foil 60, 80, 200 or 500 micron thickness, treated with 3g/m of epoxy varnish as protection against weather agents and UV rays
  • External facing: Aluminum foil 60, 80, 200 or 500 micron thickness, treated with 3g/m of epoxy varnish as protection against weather agents and UV rays
