A-Rated Windows & Doors Frequently Asked Questions
<Back To FAQ's | Next>
I notice that a B rated window or door has a negative value and an A rated window or door usually has a positive value. What does this mean?

This figure is the Energy Index and it shows how much energy the window or door will save or lose once it has been installed. This will depend on the building, local climate and indoor temperature.

A positive value means the window or door will enable more energy ( free heat ) to pass through the glass into the room than is going to be lost through it Therefore the window or door is a `free energy' supplier.
