thermopane glass

Asked April 26, 2017, 8:16 PM EDT

is there any problem with using thermopane glass in a greenhouse? Does the argon gas in the double walled sealed panels reduce UV significantly enough to hinder plant growth?

Thank you for your questions.

First, thermopane glass (as we use it here in the U.S.) is just two pieces of glass secured by a fitting that traps air between them. You can use virtually any type of glass to do that; it merely provides a vacuum to keep heat and cold from penetrating the structure in which it's installed. Uncoated (i.e., non Low "E") glass blocks UV light (10-400 nm wave length); plants use the light in the visible range (400-700 nm wave length.) Here's a link to an answer to a similar question posed on this forum.

Argon gas does not significantly reduce UV (or infrared) rays. Here is a link to an article that brings this information together.

Hope this is helpful. Good luck!
