I have a 800sq ft apartment inside a 2000 sq ft metal barn. The barn is insulated as is the apartment. Built in '06 and installed insulated H&R windows from home depot. Since I first moved in I have had a problem with moisture collecting on interior of windows mostly noticeable in morning and sometimes enough to soak a paper towel. This happens on all 4 of the windows and is beginning to cause mold to form. I am in Texas Gulf Coast area where humidity levels are very high. Help! Tired of drying my windows every day what do I need to do?

You need a system that reduces the water vapor in the air. A dehumidifier , or air conditioner system which takes the condensate away.
Sounds like you have no HVAC system working for you.
