|You'd never know that the thing was ablaze inside, because everything is ablaze outside as well. TxDOT rest area at Hardeman County, Texas.|
New lesson recently learned: the Interstate only appears light-proof while situated in areas of relatively high ambient light (urban areas, state parks with park road lamps, rest stops, Walmart parking lots, etc.). In the "light vacuum" of a remote natural or undeveloped area, it actually appears to be lit up like a friggin' Christmas tree, which is not good if one's intention is to stealth camp, an activity which also goes by the euphemism "overnight parking".
After researching the issue of what might work best to help prevent light leakage, I chose Reflectix as a cheap and versatile option with which to create window liners.
The procedure here is very simple - just measure and cut sections of it to recess into the window frames.
|I did direct measure-and-cut for all windows except the kitchen, which is the most Airstream-y window in our Interstate, curved and inset. For that one, I first did a butcher paper template so I could cut the curves properly.|
Here are a few pics of the result.
Marketing claims aside, I don't know whether I'll realize any thermal advantage if I also use these to block sunlight during daytime parking.
I will say this, however: I immediately noticed a noise insulation effect with the liners in place. Which might be good in certain public overnight parking scenarios.
Finally, there is the obvious question of where to store these liners in the Interstate's small space? Well, Reflectix seems fairly forgiving in terms of its flexibility - it can be rolled up and will open back up as flat without too much of an argument. For the short term, I think I will stack them on top of our fresh water tank, which has a dead space above it. They would also fit under one of the couches.
