Note: Both sides of the aluminum foil are lacquered with a 3g/m2 weatherproof and ultraviolet ray protection polyester lacquer.

Specification of Use:

The air ducts fabricated using ALU27 20mm, 80/80 panels can be installed in plants:

  • with air speed up to 15m/s
  • with pressure up to 1000Pa
  • indoor

 

The air ducts fabricated by using ALU27 30mm, 80/200 panels can be installed in plants:

  • with air speed up to 35m/s
  • with pressure 1750Pa
  • outdoor


Air Tight:

All joints completely sealed from with in, with glue and silicon. Conforms to DW144 Class C Standards and SMACNA.

Thermal Insulation Characteristics:

Insulating Material: Closed cell rigid expanded Poly-Isocyanurate foam, CFC free, density 44-48 kg/m3, material physiologically and chemically inert and insoluble, vermin proof, fungus proof and non-metabolic.

Thermal Conductivity: 0.0237 w/(m.k).

Water absorption less than 0% during 24 hour immersion test.

Water Vapor Diffusion (m=infinity resistance): The aluminum foil covering the panel is maintained intact after installation to ensure vapor barrier continuity.

Fire Retardant Characteristics:

Class 0 According To BS: 476 Part 6 & 7

Temperature Range:

No relevant reduction of insulation, chemical or physical characteristics of the panels is measurable when conveying air in the temperature range of (-35° C to + 110°C)

Pressure Range:

No relevant modification of insulation, chemical or physical characteristics of the panels is measurable when conveying air in the pressure of 1750 Pascal

Where the Panels of ALU27 can't be used?

  • As extractors in the kitchen, as chimneys for smoke or chemical laden smoke
  • As transportation for solids
  • Outside temperature range -35ºC and +110ºC
  • Air speed  >15m/s for 20mm thick panel and >35m/s for 30mm thick panel
  • when the negative or positive pressure inside the duct is: 20mm thick panel >1000Pa and 30mm thick panel >1750Pa
