Wren Concertina Foil Batts for Walls


  Snipped and stapled between timber studs, do not settle or slump

  Airspace created to allow external sarking foils to function - inner foil emitting 3%      radiation

  Do NOT use R1.5-2.5 batts - contact with foil causes summer heat transfer into      batts and then onto internal walls

  Zero summer heat radiation transfer - multiple aluminium airspaces formed,     similar to thermos flask

  Highest radiation load on second storey western walls

  Total R value, with external foil = brick veneer R2.6,
    weatherboard fibre/c
ement R2.5  (winter and summer)
