Dear Tim,
Re: Concertina Foil
Batts
The concertina foil
batts were installed during February in the ceiling of the second level
of the above property. The building is a two level solid brick construction
with a tiled roof. The northern rooms have existing fibreglass batt insulation
over the ceilings.
The concertina
foil batts were
installed throughout the ceilings and .over the existing fibreglass
batts. The reduction in temperature during the initial days of hot weather
spells is significant. It also appears that the heat takes less time to
dissipate during the cooler hours of the day.
The perforated foil
over the north and west windows further reduced the difference between
the external and internal air during the hot weather.
However, during extended
spells of hot weather the brick construction, which absorbs the heat,
radiates the heat for a day or so after a cool change.
Yours faithfully,
Rina Mackley
