Success story, August 2009
Japan: logistics group increases customer
base & perishable goods storage safety by
painting warehouse rooftops.
The reality of global warming means average
temperatures are rising yearly, while hot weather lasts
longer. Perishable goods are particularly sensitive to heat
and mold. Air quality and temperature during storage
periods has to be controlled.
A Japanese logistics company with a country-wide
network of warehouses has chosen Thermal Barrier Paint
Above: 2,200 SQM warehouse before painting. to upgrade its facilities’ capabilities. The company started
to paint the metal sheet
rooftops of its buildings Insulation improvement:
with Thermal Barrier Roof surface: -19ºC
Paint. Temperatures
indoors instantly drop- Roof backside: -12.5ºC
ped by up to 5°C as most Indoors: -5ºC
heat is now reflected.
Additional revenue is expected from clients looking for
controlled temperature warehousing.
The initiative also helps fighting Global Warming: the eco-
friendly paint is certified by the Japanese Paint
Association to reduce CO2 emissions and offset Carbon
