I have a 30′ x 16′ window wall that at night, according to the calcs, loses between 11,000 and 18,000 btu/hr through radiation out to space. Gotta find a way to cover it that doesn’t cost an arm and a leg and is convenient to use.
Read Rodale books on movable insulation. Too bulky. Looked up drapery & blind sights. They don’t make em’ big enough.
Most creative idea I hit on was a stage or theater curtain. But it costs around 3K for this size.
Any brainstorms? Thanks.
