Condensation is caused by the warm humid air contacting the cold windows. condensation also happens inside the TT walls. It happens slower because of the insulation, but the moisture will migrate thru the walls to the cold outer skin. There it will condense and over time cause what is known as delamination.
It happens out of sight so the only way one can know when it is happening is to watch for it on the windows. When it happens,,, take action.... IMMEADIATLY!! Open some windows and vents to let the moisture out..
Many of us run a dehumidifier to prevent it...
And don't bother squeeging it off the windows or wiping them off. That does nothing to prevent the damage that is occurring inside the walls.
Use your windows as a warning sign for when the conditions are too humid.
