Need to cure condensation

[cherryred]

I have a polycarbonate roof in an enclosed porch.
Condensation occurs when the door to the house is opened and the warm moist air from the house condenses on the roof.
I am considering fitting a plasterboard ceiling below the polycarbonate about 4 inches and filling the gap with fibreglass loft insulation.
Does anyone see any problems with this possibly come up with a better idea.

You will be able to see the loft insulation through the polycarb and will look hidious from an upstairs window. You maybe able to apply fablon or simular to the inside of the polycarb before applying the insulation to make it look better.

Yeah, that's a good point.
