U-Factor (U-Value) - An In-Depth Guide - Window Joe

WebA U-value (thermal transmittance) is a measure of how well an element of a building, such as a window or door, will transfer heat. The lower the U value the better the thermal performance of the product. Many such external elements will have to comply with thermal standards that are expressed as a maximum U value (W/m²K). WebThe U Value of European products is expressed in Watts, whereas in North America it is expressed in BTUs. To convert the U Factor from BTUs to Watts, simply multiply the value in BTUs by 5.678. For example, if a window has a U Factor of 0.21 Btu/h·ft 2 ·F, then 0.21 x 5.678 = 1.19 (W/m 2 K).

Similar to the R-value, the U-factor has to do with how much heat can transfer through the glass and out into the open air. Where the R refers to resistance, the U-factor measures the rate at which heat transfers through the glass. This means that while a high R-value is good, it’s the opposite for the U-factor. companies hiring in phoenix arizonaWeb27 Jun 2024 · You can check a window’s thermal performance by looking at its U-Value, also referred to as its U-Factor.
