Ok, winter has set in. Since (as many of you already know) we make our own electricity out here, we have quite a few skylights to bring in natural light. As expected, those skylight wells are drawing up a lot of the room heat.
Question: What if we put some cleats at the ceiling height of those wells and, in winter time, just set a sheet of plexi or tempered glass on them — would this hold back a lot of the heat loss? The air space between the ceiling glass and the rooftop glass would act as insulation, as in doublepane windows, correct? We don’t want to cover the skylight wells with, say insulated boards or whatever because we need the daylight.
Anyone know the u-value (or r-value) of plexi versus glass? Or another idea would be to mount pleated/cellular shades horizontally. Would these provide better insulation (granted, the light transmission would be less, but some light would come through)?
Thanks for input…. Tina
