How to tell dual pane/thermal pane windows on Arctic Fox?

Serial number and call Northwood mfg tomorrow and ask.

I have them and if you look at them at an angle, you should be able to see dual panes... or put a mark on one side, out or in and look at an angle.. you should see a little space between them..
Hope that helps..

Arctic Fox does not install dual pane windows "ever" unless it is a custom order....Cold weather package means nothing... in the day they asked another 1000 dollars for that option...if they do now as a cold weather package correct me and educate everyone..

my 2016 Artic fox 990 (I just brought home this morning) came with Dual pain windows, but I do think it was an upgrade that Truck Camper warehouse ordered.

I also learned on the new AF's, if you have standard windows, some of them are the ones that the bottom pane cranks out (Jalousie window), but the Thermopane the glass slides left to right

They should just do it as a regular install... pass the cost and have a better product. Why skimp?? We live in the NW and it's cold here sometimes and hot to!!...oh but who camps year round is that it? Just put the dual panes in always...

My 2015 AF 1150 came with the 'thermal pane windows' option. They are not dual pane windows like you would find in a residential window installation. There is a removable glass window pane in the dinette slider, the cabover window, and the rear dining area window. I removed mine and haven't used them since I brought the TC home. If you were camping in very cold weather they would be nice to have in place. They are listed on the Northwood Manufacturing website under options as a thermal pane window.

It's rare to see an Arctic Fox in Canada without thermo panes in Canada. I work at a dealership that sells Arctic fox and we never order them without. Having said that I have seen units in for maintenance without them, almost always imported by the owner.

Easy to tell. Look for a pice of dirt or bird doo doo on the outside of the window. Go inside and put your finger on the inside of the glass where the dirt is. You will see the greater distance and the space between the panes of glass if it has dual panes.

Or clothes the door and listen to nearby traffic. If it's loud they are single panes. If it is quiet they are probably dual panes. :)

Happy trails.

If you inner windows are removable, they are the optional Storm Windows. Thermal pane windows are true dual pane windows just like the ones in your home.
To the OP if the windows in the unit you are looking at slide sideways to open then they are true thermal pane windows.

This was my 2010 AF without dual pane windows. It had horizontal framework in the window.


There is a crank knob that opens the window outward away from the wall.



Below is my 2015 with dual pane thermal windows. They have a vertical framework splitting the window.


The glass slides open sideways. I bought mine off the dealer lot with them already installed. I'm sure the dealer optioned it this way though when they ordered it for their stock.



The rear window's don't open so there isn't any vertical framework but they are dual pane. The rear door does not get dual pane in either of it's windows. I've read that it was due to the window manufacturer not being able to guarantee the seal to hold up with the door being slammed shut over and over.




I'm not saying these examples prove one way or another but it might help. My dual pane windows are made by HEHR and there is a sticker in the corner of every window with their logo. HEHR may make single pane windows so this doesn't necessarily prove it either. The best way is to inspect the glass and see if there are two panes of glass or just one. Hopefully the seller can do that for you.
