• When installing insulation in the places and conditions
below, use the same insulation that is used for high
humidity conditions.
<Geological condition>
High humidity locations such as shorelines, hot springs, lake
or riversides, and ridges (when part of the building is covered
by earth and sand)
<Operation purpose condition>
Restaurant ceiling, sauna, swimming pool etc.
<Building construction condition>
Ceilings frequently exposed to moisture and cooling are not
covered. For example, pipes installed at a corridor of a dormitory
and studio or near an exit that opens and closes frequently.
Places (where the pipes are installed) that are highly humid
due to a lack of ventilation.
