provia and Energy Star®

Saving energy. Protecting our environment.

ProVia has partnered with ENERGY STAR® since 2002 to ensure that we produce energy-efficient, professional-class windows and doors that meet or exceed their certified criteria. ENERGY STAR windows and doors have been independently tested and certified to meet strict energy-efficiency standards set by the Environmental Protection Agency. Our engineers have worked closely with the voluntary ENERGY STAR program to design and produce entry doors and replacement windows that provide energy savings and value to our customers.

We are proud to have been recognized over the years for our efforts. In 2022, we received our 15th Energy Star Partner of the Year Sustained Excellence Award from the US Environmental Protection Agency and the Department of Energy.

Products that meet these criteria have the distinctive blue ENERGY STAR logo as part of their packaging or marketing materials.

Energy Star® blue logo with "Ask About Energy Star" tagline

At ProVia, we consistently raise the bar in our engineering and manufacturing processes to bring top-performing products to market, as evidenced by this, our 15th ENERGY STAR award. We’re honored to help American families and businesses save energy and money every day. ProVia prioritizes energy efficiency education as well, through dealer/distributor training and marketing materials.

Energy Star Program Changes

Beginning October 23, 2023, ENERGY STAR-certified doors and windows must meet new, stricter requirements. Windows, sliding glass doors, and swinging and sliding entry doors must conform to lower ENERGY STAR 7.0 U-Factor and SHGC criteria as outlined below.

Understanding the ENERGY STAR label

The new ENERGY STAR 7.0 specification represents an increase in energy efficiency and savings. The new label includes an additional line for northern climate zones, and lower values for U-Factor and SHGC, which translates to better insulating performance.

  • U-Factor – measurement of the rate of heat transfer; indicates how well the window insulates. Values typically range from 0.25 – 1.25; a lower U-Factor means better insulation.
  • SHGC – (solar heat gain coefficient) the amount of solar energy transmitted through the window; measurement of how well the window blocks heat from sunlight. Values range from 0.25 – 0.80; a lower number indicates lower level of solar heat transmitted.
  • The Northern Climate Zone has several recommended ranges due to colder climate and temperature variations. The lower the U-Factor, the better the window is at keeping cold air out.
  • The overall lower U-Factor and SHGC values of ENERGY STAR 7.0 offer increased energy efficiency, peak performance, and savings to you.

U-Factor is the insulating value of an entire window system. Lower numbers reflect better insulating value.

Solar Heat Gain Coefficient

Solar heat gain coefficient (SHGC) is the amount of heat from the sun passing through the glass. Lower numbers indicate glass is keeping heat from entering your home. SHGC is measured on a scale from 0 to 1.

Visible Transmittance

Visible transmittance is the amount of visible light passing through the glass. Higher numbers indicate glass is allowing more light to enter your home. Visible transmittance is measured on a scale from 0 to 1.

Air Infiltration

Air infiltration measures how much air is entering or escaping through a window. The number shown represents the maximum air infiltration allowable by NFRC listings.
