We use the default table from the Model Energy Code to establish the thermal Performance values for our other windows. The default table is a punitive table. It is set to give low numbers and encourage use of other methods of establishing values. For this reason some of our windows may be better than these numbers will indicate. Size or type of operation are not a factor with the default table.
