I just finished construction on a new house. I put in wood casement windows. I have noticed on cold mornings that I have a small amount of condensation on the inside of the windows. the walls are 2x4 with regular batt insulation. I do have some of the windows that have 2x6 studs, they are under covered porches, these are not getting any condensation. I'm keeping the temp inside the house at 67 and the humidity is right around 50 percent. How can I prevent the small amount of condensation on the windows in the 2x4 walls? Why is it not happening on the other windows in the 2x6 walls? Could it be because the window frames were not foamed around well enough?
