- Acts as its own air barrier
- Fills all holes & crevices preventing air
infiltration
- Retains shape & thickness indefinitely
- Allows zero water infiltration which makes it
impervious to mold
- Greater energy savings because of permanent barrier
- Simple application means faster construction
time
- Higher R value per inch
|
- Requires an air barrier
- Leaves gaps and holes around obstructions like
pipes & electric outlets
- Sags and deteriorates over time
- Can be permeated by water allowing mold growth
in fiberglass batts
- Energy efficiency decreases over time as fiberglass
degrades
- More involved installation means longer construction
time
