temperature above the ceiling is likely to exceed 86°F
(30°C) and a relative humidity of 80%.


Make sure that the insulation material is made of glass wool
or polyethylene foam, has a minimum thickness of 3/8 in.
(10 mm), and can be accommodated in the opening on the
ceiling.

fulfilled and that meets with your customer’s approval.
• A place where cool (warm) air is delivered to the entire
room.
