The lower the number, the better. To meet Energy Star requirements, windows must have a u-factor at or below 0.27.

Visible transmittance refers to how much visible light comes through the product.

The higher the number, the more light is transmitted. VT values typically range from 0.30 to 0.70.

Solar heat gain coefficient measures how well a product blocks heat caused by sunlight.

The lower the number, the more it will help reduce the use of air conditioning and energy use. In cold climates, a higher SHGC is desirable to collect heat from sunlight. SHGC typically ranges from 0.25 to 0.80.
