6 Metrics for High-quality Windows

To buy efficient and durable windows, homeowners must learn how they can actually assess their performance. However, most people are oblivious of the fact that there are certain metrics they can use to do such a test.

  1. U-Factor

To determine a window’s rate of heat loss, U-Factor is used. A low U-factor means that a window has better insulating properties. It is beneficial for residents living in hotter places, so homeowners must be aware of which U-factor best suits their climate.

  1. Solar Heat Gain Coefficient (SHGC)

Before picking your windows, check its SHGC. If it is low, then it transmits less solar heat, giving you decreased solar radiation. SHGC is commonly expressed as a number between 0 and 1.

  1. Visible Transmittance (VT)

Nowadays, modern windows have selective coatings that can reflect different amounts of visible, infrared, and ultraviolet (UV) light. With VT, homeowners can indicate the fraction of visible light transmitted through their window.

  1. Air Leakage (AL)

Frequent window replacement can be avoided once you assess the main reason for heat gain or loss inside your house. Most of the time, it is because of the amount of air that passes through window cracks. Homeowners must choose the ones with an AL of 0.30 cubic foot per minute/(sq foot) or less. 

  1. Condensation Resistance

A high rating is what you should be looking for once you assess your window’s condensation resistance. The higher the number, the better it can resist condensation on the inside surface of a window.

  1. Sound

When you have a high-performing airtight window, it should generally filter outside noise. The more noise it filters, the higher the chance that it can prevent air leakage.

In the end, evaluating your windows’ performance is something that you should do before buying one for your house.
