Well, I got some time this evening to pick up some stuff to make 4 of those indoor thermal 'windows'.
Got two of the 48" x 25' rolls of plastic sheet. It seems like pretty good stuff.
48 in. x 25 ft. Clear Plastic Window Installation Kit-V4825/4 at The Home Depot
Also stopped off at Lowes and picked up 4 screen kits to use as frames.
I want to see if it's possible to use a single frame to make a double sheet (dual pane) window insert.
I want to try laying a trimmed 48"x48" sheet out on a frame, tacking it on with some double-sided-sticky tape.
Then pull the edges of a second 48x48 sheet around from the other side.
Then push the rubber spline into the slot, retaining both plastic sheets.
Or alternately, try tacking on the wrap-around sheet first and then laying
the second smaller sheet on top and spline it all in..
I also picked up some over-sized spline, just in case the kit stuff is too small, to hold these thin sheets of plastic.
The problem I foresee is overlapping the wrap-around at the corners.
The plastic is going to bunch up there.
And I'll have to make a 90d cut in exactly the right place, on all 4 corners.
If it's too hard to accomplish this, I'll go back to plan
A, and go buy 4 more screen kits.
Put all 8 together and use two on each window. A wider double pane..
Wider would work better too..
