Most windows sold today are Low E and reflect heat away from the glass.But something you will not know unless it happens to you is Low E does not last forever.I installed Low E windows in my house myself in 1998 or early 1999 and about 6 years ago I noticed it was now quite hot standing in front of the windows.I researched life span of low e windows and sure enough they last 20 years maybe a bit less maybe a bit more.Sucks!Cleaning them did not degrade them all the south facing ones act the same and 2 never get cleaned. but they do not get dirty either.Things to know.
