Awhile back in a different topic I mentioned I was doing something to improve the thermal efficiency of out trailer. So here we are, ready to reveal the what and the why and the how.
Back when we were in planning stage we were adamant that we wanted a nice sized window so when we were inside we would have daylight and we would have a view. Sometimes we do camp where there are great views. Like this one..... Spring break end of March, beginning of April; SE Utah a few miles from the Buckskin Gulch / Paria slot canyon trail.
But we also knew the window was going to be a thermal hole in the side of the trailer. Heat pouring out in cool weather and heat pouring in, especially when the sun would be striking the glass. We are happy we decided to install the window. No doubts about that. However the heat gain / loss is another matter. So here is a solution.
First view...
Second view...
And a third view...
It's a window plug! Two inches of XPS foam. A 1x poplar frame around the perimeter. Silver mylar contact glued on the side that faces the glass. The same plywood we used on the interior walls facing in. A couple of barrel bolts to keep the plug in place when we want to block the light / heat. We can store it in the back of the truck at other times. Makes a difference. So yeah, all those with windowless CT's can say "I told ya so". But we have the best of both worlds.
Yes, this is a hiking trail!
