Low-E glass.

blockmanjohnMarch 23, 2010

I am building a small greenhouse off of my living room.It will share a radiant heat loop with the house and will mainly consist of stock windows and skylights. My question is should I order the windows with low-e glass or plain insulated glass? I would like to maximize the amount of solar heat the structure retains during winter days. In the summer it would be ventilated after a certain temperature is reached. If any one has any experience with this situation I would greatly appreciate some advice. Thanks, John.

I like it that you are extending the radiant out to the GH. The low-e glass is a good way to go if you can swing it, as it increases blockage of long-wave radiation and that's what you want.

Low E glass costs me some 10 to 15 % more than standard insulated glass, depending on the brand. When I first began installing this product in my homes, years ago, it cost 30-40% more, as I recall. A good value, but shop it.
