Moisture accumulates in poorly vented attic because:
a. Moisture rises
b. Moisture attracted to cold
c. Warm air rises & condenses in the attic
d. All of the above
Give this one a try later!
Warm air rises & condenses in the attic
The insulation vapor barrier should face toward the heated side (living space) of the
insulation because:
a. Moisture could condense in the insulation if the vapor barrier faces the cold side.
,b. The vapor barrier will deteriorate if exposed to extreme cold
c. The vapor barrier facing can be a fire hazard if exposed on the attic side
d. The insulation must 'breathe' the same air as the unconditioned space
Give this one a try later!
Moisture could condense in the insulation if the vapor barrier faces the
cold side.
