Dave Ellis,
In the summer of 2009 I had my new Cedar Ridge composite siding (w/foam backing) and Simonton windows installed by Hometown Exterior Design. I can remember that besides the claims of having a quieter home I was also told that I would actually see my electric bill reduced.
The claim of a “quieter home” was immediately proven.
As for the electric bill?
Well, this year (from 12/28/09 til 01/29/10) with the new windows and siding I averaged 50 kwh per day.
During the same period last year (2009), I was averaging 78 kwh per day (but, it was also much colder last year). Then, during the same period in 2008 I averaged 59 kwh per day.
So, I think the new windows and siding has proven itself.
Thanks, Hometown Exterior Design.
