Freezing cold bathroom
I recently renovated my house, the bathroom is on the second floor. Since it was recently renovated, its the only room on the second floor with insulated walls. It also has a sliding windows in where the shower is. A ceiling fan was put in and it vents out of the roof. There is about a 5 foot span between the ceiling fan and roof exit.
There is only about 3 inches of insulation in the attic, I plan on adding another 10" or so to bring it up to an R38.
Until then, its so cold that when water hits the window it pretty much freezes, you guy have never steered me wrong so far, what can i do prior to upgrading the insulation in the attic to help?
The can of the fan has no insulation on it, neither does the flexible duct out of the roof. I might just go buy some insulation and put it in the attic, would that be best for now? Thanks
