If I were choosing a TT for windows, I would set my mind on the insulated windows. They make a HUGE difference.

Hehr 6400's are used in Escape trailers. These are 1/2" thick double-pane frameless. These are an option along with the tank heater pads, spray-on undercarriage insulation, and extra interior insulation.

Having said that, the rating of a single-pane window is about R-0.7 and a double-pane with a 1/4" air gap is R-1.7. That's a lot better but still not great. From my experience it mostly helps with condensation issues. I wouldn't go without double-panes, but you will still need a lot of furnace in truly cold temps.

One other advantage of the frameless is that there is no frame to conduct cold inside. The metal frame in most RV windows conducts the cold inside and water vapor condenses on it, often dripping on the inside. That is probably the biggest advantage of frameless over framed in cold conditions.

Agreed - the conduction of the frames is terrible. I've thought about trying to rework them with a thermal break of some type, but it probably wouldn't make much difference. Perhaps spraying the inner frame with some plastidip would do it LOL.

Outdoor RV installs frameless thermos pane windows on all models except the Black Rock.

Without pics....I have no idea what you are talking about.

OK...I followed the google link and even watched some videos.

Frameless look very nice but it appears that framed are more practical.

I guess it comes down to taste and how YOU plan on using your TT.

I like our frameless windows more than the framed ones in our previous camper. Easier to open and clean. Can leave open in the rain. No problem with fresh air with the Fantastic Fan running. Least important to me is the look, but they do look better.

I've had both, double pane framed on a Bigfoot and single pane frameless on my signature vehicle. I preferred the double pane for insulating qualities over the frameless. I prefer the exterior look of the frameless windows. My double pane windows had gasket creep but I believe that was a manufacturing problem.

I buff the water spots off my windows with a power buffer. Piece of cake on the frameless, pain in the neck on the framed windows. This something to consider if you want your windows to shine.

can someone post photos of what the two types look like? I'm pretty sure I have framed windows, so I'm not sure what a frameless window looks like.

Hi Doug, On another subject, Did you get your recall letter from Keystone this week about a national recall on Bullets because of a wiring problem with the AC unit on the roof? Can cause a fire. I am taking mine in to Hitch RV this Friday. Mine is a 2014 285RLS , similar to yours. It affects Bullets from 2011 to 2017. Must be a ton of them.

I googled here.

IF you look at the rearmost windows on the sides of minivans or on many extended cab pickups, there are windows that open and close on hinges. Those are very similar to what is referred to as frameless windows. By the way, they never leaked on my various vehicles. Don't see why they would to leak on an RV unless they're made of inferior materials.
