U values are measure in watts per square metre kelvin or w m2 k.

Sliding door u values explained.

Nfrc u factor ratings however represent the entire window performance including frame and spacer material. The lower the u value is the better the material is as a heat insulator. The lower the u factor the more energy efficient the window door or skylight. U values are used to determine the insulating efficiency of the window and all of its components.

U values indicate the overall performance in retaining heat and preventing it from escaping to the outside. For windows skylights and glass doors a u factor may refer to just the glass or glazing alone. U values measure how effective a material is an insulator. This is different than r value that would be used to determine the energy efficiency of just the window pane thus a window with a u value of 1 is more energy efficient than an window with a u value of 5.

In simple terms the lower the u value number the better the thermal performance of the window. Energy efficiency explained when talking about patio doors the u value refers to how efficiently the window glass the door as a whole keeps in heat. The better it is at doing this the better rating it will have. The u value is a measure of heat transfer across a building material.
