Anti-glare foil sarking under tile roofs

  • Foil side facing downwards, functions with a 50-100mm airspace facing downwards acting as a radiant heat barrier/low emitter 3%, and vital protection for cooling ductwork)
  • Functions also for waterproofing, since first invented in Australia in 1952, as ‘sisalation’.
  • Breather fabrics must not be used under tile or metal roofs, e.g. otherwise high levels of radiation will enter roof spaces and increase residential cooling costs.

Anti-condensation foil building blanket, for specific use under metal roofing.

  • Foil side facing downwards, reduces risk of condensation, as well as acting as a summer radiant heat barrier/low emitter 3%, and protection for cooling ductwork
  • The vast majority of the ‘summer heat flow down R-value’ comes from the foil, not the bulk. A fact the general insulation industry refuses to confirm.
  • metal roof & metal foil are separated by fibre insulation, whereby in cold situations the foil always has a temperature higher than the metal roof

Anti-glare foil house wrap

  • Vertical foil in walls facing inwards functions with a 25 mm airgap (for summer & winter) for resistance against radiant heat transfer.

Inward facing foil surfaces in walls

  • Addition of R1.5-2.5 fibre eliminates 100% thermal function of foil, because of heat flow by ‘conduction’
  • Climate Zones 1,2,3,4,5 should use foil insulation products alone in walls. Fibre batts can be justified in walls for locations with substantial winter heating seasons, i.e. Zones 6,7,8.

Concertina profile foil laid on existing bulk insulation in ceiling (stapling unnecessary)

  • Combination principle of foil & bulk for dual winter & summer climates, being superior to R5,6.7 fibre batts alone
  • Zigzag foil profile has downward triangular airspaces acting as a powerful downward radiant heat barrier/low emitter 3% & 97% reflection upwards
  • Permanent thermal performance exists, even if dust slowly accumulates on upper foil surfaces

Concertina shape foil stapled to roofing rafters

  • Double-side foil surfaces facing well defined upper and lower airspaces, with 97% high reflection upwards & 3% low emission
  • Retrofit solution for existing roofs where no foil sarking exists
  • Thermal solution for attic extensions requiring maximum control against 80-100degC roof radiation levels, outperforming bulk insulations
  • Radiant heat shield to protect air-conditioning ductwork

Concertina shape foil wrapped around air-conditioning ductwork

  • Zigzag foil profile with dual airspaces maintained outward and inward, as powerful radiant heat barrier to reduce roof space radiation penetrating air-conditioning ductwork insulation
  • Significant reduction in running costs of cooling systems, either refrigerative  or evaporative.

Concertina shape foil stapled to floor joists (or any segmented foil design)

  • Expandable foil profile, reflecting downward winter radiant heat from timber floors
  • Bulk insulation is totally unnecessary and not advisable under timber floors, for water absorption reasons and immediate attraction for rodent infestation
  • Special Note: Roll form aluminium foil laminate was recommended as the primary underfloor insulation option when New Zealand’s mandatory thermal insulation regulations were introduced in 1977, and in Victoria in 1991.

Retrofitted double-sided aluminium foil insulation – underlining factory roof with no foil sarking (Tooronga, Melbourne 1984)

  • Highly powerful radiant heat barrier, 97% reflection & 3% low emission, emission surface keeps functioning if upward surfaces is slowly impaired by dust
  • Aluminium foil insulation is the best performing solution for radiant heat control, which most bulk insulations cannot match.

  • Used to protect the cab and occupants from extreme radiant heat and flame passing through the window and glass
  • TBA Firefly is a member of AFICA

Durable aluminium foil woven fabric wrap Wallace’s Hut, High Plains Victoria

  • Emergency fire protection for remote historic cattleman’s huts, and also adopted also in California USA
  • Reflects high radiant heat loads during flashover period
