His vinyl siding was warped and damaged within a couple of years of the house being made. So yeah - this happens. The house next door has a window which reflects onto my lawn in the evenings. If I walk through the beam while mowing the grass I feel the heat instantly like stepping into a death ray. Luckily that beam is only there in the evenings and moves very quickly.<br /><br />You are right about the cause, slight curvature + very reflective glass (low E coatings reflect the infra red heat energy).<br /><br />This is probably common in the south where glass is used to stop solar gain. In the north the coatings are used to keep heat in and might not work as effectivelyPhil Ballhttps://www.blogger.com/profile/11611303173189761737noreply@blogger.com
