Replacement Windows Houston TXHaving replacement windows installed on your home anywhere in Greater Houston is a significant financial investment. Fortunately, it is an investment that provides you the opportunity to greatly improve your home’s energy efficiency. Just be certain that, to maximize the amount of energy – and money – you save, choose replacement windows that bear the ENERGY STAR® certification label.


ENERGY STAR® is a government-backed symbol for energy efficiency. Home appliances, consumer electronics, office equipment, building materials – these are just some of the consumer product categories for which a variety of brands have been able to achieve ENERGY STAR® certification. Replacement windows, as well as doors and skylights, generally must meet or exceed minimum government standards for energy efficiency by excelling in the following performance categories:

  • U-Factor – This measure tells you how well a window insulates. The lower the U-Factor, the better.
  • Solar Heat Gain Coefficient – Measured on a scale of 0 to 1, SHGC tells you how well a window blocks heat caused by sunlight. Look for windows with lower SHGCs.
  • Air Leakage – The rate at which air passes through window joints, AL is measured in cubic feet of air passing through one square foot of window area per minute.
  • Visible Transmittance – All windows let in light; VT is simply a measure of how much.
  • Condensation Resistance – The higher the condensation resistance factor – scored from 0 to 100 – the better a window is at preventing moisture buildup.
