What is the difference between an insulated and a normal rolling shutter?

A normal shutter has single-skin slats that block entry but pass heat and noise easily. An insulated shutter has double-skin slats with foam inside, which slow the transfer of heat and reduce noise. It also tends to be heavier, so the motor and barrel are sized for it.

If you run cooling or keep goods at a set temperature, an insulated shutter is worth considering. Qasar Al Neil Automatic Doors can advise after seeing how the unit works.
