We are looking at a house built here in Central Texas, was built in 2001 and
I am trying to figure out if there is a way to tell if the windows have
"LowE" glass in them...Is there any way to tell after the fact?
Shine a heat lamp on one side from about a foot away, and use your hand to
feel how much heat can be felt from the other side. Plain glass blocks
almost none of the heat, while low-E glass will block a lot of the heat.
How much heat gets blocked will depend on how "good" the low-E windows are.
