Energy Efficiency

Our windows and doors aren’t just tough – they're also energy efficient help you save energy. All standard Integrity products meet or exceed federal ENERGY STAR® guidelines. Because our windows and doors are built to the highest energy efficiency standards, you can reduce your environmental impact and see significant savings on your heating bill over the long term.

ENERGY STAR

ENERGY STAR® is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy designed to recognize products that meet strict energy efficiency guidelines. All Integrity products are ENERGY STAR rated, ensuring not only energy savings but potential tax credits when you replace old, inefficient windows.

Most Efficient

The U.S. Environmental Protection Agency launched the ENERGY STAR® Most Efficient Program for the fenestration industry on January 1, 2013. The program is designed to recognize products that meet the highest energy efficiency guidelines. Integrity is pleased to have several products awarded the ENERGY STAR® Most Efficient mark in 2013 and 2014 for both the Northern and North-Central zones. A full list of recognized products, performance values and ENERGY STAR® Most Efficient Program criteria are available at www.energystar.gov/mostefficient.

2013 Energy Tax Credits

The Residential Energy Efficiency Tax Credit was retroactively renewed by the American Taxpayer Relief Act of 2012. It will expire on December 31, 2013. This credit applies to energy efficiency improvements in the building envelope and other energy saving improvements. Owners of existing homes may receive a tax credit worth 10% of the cost of upgrading the efficiency of the building's envelope. The tax credit is applicable for a dwelling in the United States that is owned and used by the taxpayer as a primary residence. Maximum tax credit for all improvements made from 2006 to 2013 is $500, only $200 of which can be windows. A homeowner who buys both windows and doors can qualify for the entire $500. Doors are not included in the $200 limit, so that $500 credit can include doors if the $200 max for windows is achieved.


If a taxpayer claimed $500 or more ($200 for windows) of these tax credits in any previous year, any purchases made in 2012 or 2013 will be ineligible for a tax credit. To be eligible for the credit, the improvements must meet the prescriptive requirements established for it under the 2009 International Energy Conservation Code. Eligible windows and doors need only to be ENERGY STAR qualified products. Installation (labor) costs are not included. Many Integrity® exterior doors and windows qualify. All windows and doors must have been installed by December 31, 2013. See files of qualifying windows and doors at the links below.

Tax Credit Qualification

  1. Older windows and doors were replaced with more energy-efficient Integrity window and door products that are recognized as ENERGY STAR qualified products. Almost all Integrity products are labeled ENERGY STAR.
  2. All windows and doors must have been installed by December 31, 2013.
  3. Save the purchase receipt and all NFRC/Energy Star labels from the windows and doors installed.
  4. Print the Manufacturer’s Certification Statement.

Efficient Construction

Integrity products are energy efficient by design, thanks to the low-conductivity of the Ultrex framework keeps heat transfer to a minimum and the insulating properties Low E II glass with argon gas. Low E II features a double metallic coating on the inside glass surface to reflect or absorb warmth and reduce damaging UV rays.

The following factors are used to determine a window’s energy efficiency:

  • U-factor – This measures the rate of heat loss and how well a window insulates. The lower the number, the better a window is at keeping heat inside a building. The U-factor is key in the winter months, and important to consider in choosing a window.

  • Solar Heat Gain Coefficient (SHGC) – This measures how well a product blocks heat from the sun-the lower the number, the better. This is valuable in southern climates or high sun intensity areas where you might actually want to keep the sun’s heat out of your house

  • R-value – This measures resistance to heat loss. Many people are familiar with the R-value because of its use in home insulation. But actually, for windows and doors, U-factor and solar heat gain coefficient are more important measurements.

  • Design Pressure Rating – The “DP” measures the amount of pressure a door or window will withstand when closed and locked. Each DP rating also establishes other performance factors such as water penetration; air infiltration; structural pressure; forced entry; and operational force. The higher the DP numbers, the better the performance. Look for the certified hallmark of the Window and Door Manufacturers Association.

LEED Certified

The U.S. Green Building Council’s LEED® (Leadership in Energy and Environmental Design) certification recognizes projects that meet stringent standards of environmental and public health excellence. While individual building components themselves are not certified, Integrity’s long-lasting and energy-efficient windows and doors can be an integral part of your project’s LEED certification.
