When determining how much insulation you need don t guesstimate calculate.
Drop ceiling r value.
For an insulated space it does not mater so much if you miss the r value of an r30 insulated ceiling by r1 its only a 3 error in heat loss.
R values increase with insulation thickness so the depth of.
In warm regions r 30 insulation is often sufficient for ceilings while colder climates might require insulation values up to r 49.
R values of selected suspended ceiling products designs building energy audits.

The higher the r value the greater the insulation performance.
