Wren Concertina Foil Batts for Walls

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/cement R2.5 (winter and summer)
