BTU rating on windows
I'm back with a new question on the same problem. Had a window salesperson come out. Sat through the presentation. He used a BTU meter and a heat lamp on his window compared to ordinary glass and on a double pane and mine. Remember my collapsed class were fixed. The meter was set for 400. Ordinary glass read 400. Then double pane and the meter read like 320. His window read 40. My repaired windows read 400. A brand new window I receivied from Anderson read 240. Anderson refuses to replace the widows stating their fix for the collapsed glass is all they will do and need to do. Should not my windows have the same btu reading as the new window? Still get condesation on the windows Having curtains or blinds don't seem to make a difference.
Thanks for your help.
