What is the thermal transmittance?

This is the average heat flow that passes through a structure which separates a heated environment from the outdoors or a heated environment from an unheated one.

Why is it important?

The goal is energy savings, and therefore a reduction of heat loss. You need good quality frames that allow a decrease in dispersion of heat.
