← Back
Why does a fibrous batt or blanket insulation slow heat flow through a wall or attic assembly?
A
It reflects essentially all radiant heat back toward its source regardless of how it is installed
B
It seals the cracks and penetrations in the assembly so outdoor air cannot leak through
C
It absorbs heat during the day and releases it outdoors at night
D
It traps air in many small pockets, which slows conduction and limits convection currents within the cavity
