Can someone help eplain low-e?
I am looking at Andersen 200 series windows.
I was told at HD that the low-e is on both of pieces of glass and this will reflect heat from the sun back outdoors and heat in my home back indoors in the winter months.
At my local lumber yard I am told it is only on one peice. The lumber yard said the low-e will only reflect heat from the sun back outdoors and will not reflect heat back indoors in the winter months.
If the lumber yard is correct why should I spend the extra money for low-e on north facing windows?
