It is particularly important in colder climates where heat loss is a concern.

Solar Heat Gain Coefficient (SHGC)

The Solar Heat Gain Coefficient measures how much solar radiation passes through a window or door. The SHGC value ranges from 0 to 1; the lower the SHGC number, the less solar heat it transmits into your house.

Understanding this value can help you control indoor temperatures during hot summers. A lower SHGC will limit solar heat gain and keep your home cooler.

Key Points about SHGC:

Lower SHGC means less heat gain from solar radiation.
It helps reduce cooling costs in hot climates.
Some regions may have regulations regarding minimum SHGC values for windows.

Visible Transmittance (VT)

Visible Transmittance measures the amount of visible light that passes through a window or door. This value also ranges from 0 to 1, where higher values mean more light is transmitted.

Having knowledge about VT can help you optimize natural light in your home, thus reducing the need for artificial lighting and lowering energy costs.

Key Points about VT:

Higher VT means more natural light.
It reduces reliance on artificial lighting, saving energy.
Too much VT can cause glare; balance is key.

By understanding these technical terms, homeowners can make informed choices when selecting windows and doors. These factors – U-factor, SHGC, and VT – play a considerable role in determining the energy-efficiency of these installations. Prioritizing lower U-factor and SHGC values along with appropriate levels of VT could result in noticeable energy savings and increased comfort at home.

When choosing windows and doors for your home, energy efficiency, practicality, aesthetics, and affordability should be top considerations. This guide will help you understand how to select the most suitable windows and doors for optimal home performance.
