Low Temperature Buildings

| Low
temperature buildings used for food processing, storage and other
applications create one of the most hostile environments to which
insulation can be subjected. Such buildings, in order to serve their
intended purpose, must maintain interior temperatures that are cool,
sub-freezing, or even sub-zero. Under these conditions, it is critical
that the building wall, roof and floor insulation possess superior
water resistance qualities and stable reliable R-value. These are
the attributes that make extruded polystyrene (XPS) the preferred
insulation for low temperature buildings—an insulation that
will endure the environmental demands while enabling the economical
maintainence of a low temperature interior.
The constant low interior temperature in low-temp buildings creates
moderate to high temperature differential and moderate to high vapor
pressure differential between inside and outside. Temperature differences
are the force that drives heat energy into the building, energy
that must be removed via mechanical chilling equipment. Vapor pressure
differences are the force that drives water vapor (humidity) into
the building. The building insulation must be resistant to moisture
absorption while under constant exposure to vapor intrusion due
to vapor pressure differences between inside and outside.
