bathroom fan exhaust

Two second floor bathroom fans exhaust to a stack that runs up thru the roof. The builder used PVC pipe (4"?) from the fans to a "T" and then to the stack. I have always seen flexible exhaust hose in these applications. Is the PVC OK? BTW, I have wrapped insulation around them to prevent condensation when the warm, humid air reaches ambient temperatures in the attic.
