Choosing windows can be a complex decision, especially when you consider the importance of thermal insulation to achieve energy savings.
How do you know if a window meets your thermal insulation needs? The answer lies in thermal conductivity, measured by various coefficients.
Thermal transmission coefficient:
– The Uw coefficient measures the thermal conductivity of the window as a whole.
– The Ug coefficient focuses on the glazing.
– The Uf coefficient concerns the window frame.
– The solar factor Sw evaluates the window’s ability to transmit solar heat indoors.
Approximately 25% of a home's thermal loss occurs through windows, highlighting the importance of choosing windows with optimal thermal conductivity.
– A lower Uw coefficient indicates better thermal insulation.
– For the solar factor Sw, a number close to 1 indicates better transmission of solar heat.
By considering these factors, you can choose windows that contribute to your comfort and the energy efficiency of your home.
