Glass will happily absorb infrared and reradiate it outside. In the dark it's just a single pane window ... a really big single pane window. Such things are known for being really good at transferring heat. The rule of thumb is a single R value per pane.
- schiffern 10y ago>Glass will happily absorb infrared and reradiate it outside. And some fraction will also radiate inward, so overall the total radiant heat flux is lower. This is the aptly named "greenhouse effect."
- credit_guy 10y agoOr not. The so called greenhouse effect is not what keeps a real greenhouse warm. Here's the relevant wikipedia quote: "a greenhouse is not primarily warmed by the "greenhouse effect". A greenhouse works primarily by allowing sunlight to warm surfaces inside the structure, but then preventing absorbed heat from leaving the structure through convection." https://en.m.wikipedia.org/wiki/Greenhouse_effect https://en.m.wikipedia.org/wiki/Greenhouse_effect
- schiffern 10y agoHah, I stand corrected. Not-so-aptly-named I suppose!
- kitd 10y agoCould the glass be treated (or have a layer applied to it) inside to reflect any IR back inwards? A bit like you can put on the outside for large glass areas exposed to the sun.
