Introduction

In the realm of building construction and energy efficiency, the thermal transmittance of windows plays a crucial role in determining the overall energy performance of a building. The MetraUW program is a specialized tool designed to calculate the average thermal transmittance of METRA windows, adhering to the stringent standards set by the EN-ISO 10077-1 standard. This program empowers users to create various types of window structures using METRA series products, allowing for the calculation of the Uf value of any section of the structure, and ultimately determining the Uw value.

Understanding Thermal Transmittance

Thermal transmittance, denoted by the symbol U, is a measure of the rate at which heat is transmitted through a material or a structure. In the context of windows, thermal transmittance is a critical factor in determining the energy efficiency of a building. The Uw value, in particular, represents the average thermal transmittance of a window, taking into account the various components such as the frame, glazing, and spacers.
