 What is U-Value and solar heat gain coefficient on glass packs of windows?

  The minimum recognized by Energy and Utilities Companies across the country is .35 in either category to certify as an Energy Star Window.  The lower the number the more energy efficient  All of the brands we use qualify with some lower than .30.

 What about warranties?

 Most of our siding and window products have Lifetime transferable warranties.  The vinyl siding products cover against cracking, splitting, chipping, peeling, and hail.  The steel siding includes all of the above plus rust warranty.  They all have limited fade warranties as well.
