Hey guys - I need some information re: condensation problems. I've just disposed of the seats on my prevost and I've noticed condensation on some seams across the ceiling as well as around the emergency hatch. I don't see any gaps in the seams up top but the hatch is not a perfect fit. | ||

If I'm not mistaken that sounds like sweating if you were running the AC. That's one reason people put so much effort into insulating their coaches to prevent the moisture forming | ||

Those areas may be aluminum channeling directly connected to roof, which will transfer outside cold to inside and provide a surface for condensation of moisture. What are you using for heat? do you have any vents cracked to dispose of moisture? | ||

hey John - the bus is sitting in a lot while we work on her. We are not running any heat or air. The condensation occurs in the morning from overnight - I was just wondering if this could be taken care of with insulation or rubber roof coat??? | ||

If you have condensation , it is still slightly warmer inside than outside and accumulated moisture in inside will condense on uninsulated interior areas. Some insulation will take care of this. Don't know how effective the rubber roof coat is. Personally, I'd hate to put that coating on my roof. But that is just me. I don't know how that stuff is to keep nice and clean or durability over the years. Hopefully, you have room to add insulation on the inside. The roof coating is something that could be added after the coach is completely finished, so you don't have to disturb it for holes through roof. eg. vents, AC, etc,. | ||

We use damp-rid and very liberally when in storage especially down in the basement where our inverter resides. The windshields were a problem overnight when camping and we have found a portable fan blowing on them works very well. | ||

There will ALWAYS be moisture in the coach, with or without insulation. It is a function of humidity and temperature change between inside and outside. You may notice the condensation increases as you spend more time breathing in the coach. Your challenge is to insulate properly in order to prevent the condensation from forming inside your walls and rusting the bus structure, and forming mold and mildew inside the walls, which gives many an old conversion that musty smell. Another good reason for designing in some storage air circulation, instead of locking it up tight. Make no mistake, there will be condensation, it's all a matter of whether it will be where it may evaporate again the next day, or just keep getting wetter. Condensation increases dramatically when you are living in the coach. Want to try? Leave your maintenance manual open on the table for a week or two and then see how wrinkled the open page gets. happy coaching! buswarrior | ||

I have three roof vents, and always keep the center vent cracked open about 1/4 inch. Since then, no more condensation. Jay 87 SaftLiner | ||

James is correct. Vent the coach. We went skiing Christmas 06 and I kept my vent open a bit with the fan on low and with 4 adults in the coach in 8 degree weather we had no condesation. Yes, it takes more heat, but before I did this I would get a glaze of ice all over the inside of my front windshield which was a mess to remove. David | ||
