The U value of a window or door is a measure of thermal transmittance. It’s used to convey how heat is transmitted through the door or window. A good performing window has a low U Value. U Values for Ecoline’s tilt and turn windows, by design, are better. As is their airtightness.
Generally, the lower the U-Value of a window or door the better. Low U-Values indicate that a window will perform well in maintaining the indoor temperature of a customer’s home.
U-Value Measurements
For windows, there are some specifics that differ when making U-Value measurements compared to other surfaces, these include:
1. Ug Value = Which measures the thermal performance of the glass.
2. Uf Value = Indicates the thermal performance of the window frame.
3. PSIG = Which indicates the thermal performance of the frame spacers.
These factors combined give you the final U-Value of your window.
