Total R-value of the structure (R T ) is the sum of all component R-values, including the internal airspaces and the surface air films
on either side of the structure. NB: Framing timbers are excluded from the Total R-value (R T ), as per AS/NZS 4859.1:2002.

Perforated CONCERTINA FOIL
BATTS TM allow moisture
drainage and maximum
breathing of timber flooring,
and combined with still
airspaces, produce high and
consistent thermal
performance, reflecting 97%
of radiant heat back to the
floor.
FOIL BATTS do not absorb
or retain heat and therefore
do not create warm cosy
nesting environments for
rodents or pests.
