want to finish inside my porch but the ceiling has a metal silver top roof that sweats in summer and winter with heater on.what can be used to insulate ceiling that wont leak on drop ceiling.


Insulation will stop the sweating. The sweat is condensation, warm air hitting a cold surface...a frying pan lid. Insulation makes the "hitting" happen in super-duper-slow-motion so the air cools or warms to the metals temperature before it hits for no more sweating. A minimum of 4-inches or 2 to 3-layers of Styrofoam or any other rigid foam panel or board will do the trick and keep the heat in the porch a lot longer.
