Greenhouse effect

Greenhouse effect

(OP)
What materials other than glass could be used to build a greenhouse?
If cost of materials were not an issue, what materials ( resins?)would give maximum thermal efficiency.
TIA

RE: Greenhouse effect

Pretty much anything that's transparent in the visible.

RE: Greenhouse effect

Actually a greenhouse needs to transmit visible and short-IR solar wavelengths, and reflect the long-IR that's emitted by the contents of the greenhouse (usually peaks in the 8 micron range). Glass works great because its typically transmission cutoff is around 3 microns. For other materials, hunt around NREL's web site, or keyword-search on "solar absorptivity". Or look at the ratio of solar absorptivity to emissivity.
