SUPERIOR QUALITY

InNergy
Innergy is a cutting-edge, energy-efficient alternative to traditional aluminum reinforcement, offering a significant advancement in the performance of windows and doors. It surpasses aluminum by providing superior thermal efficiency and strength, enhancing overall energy performance like never before.
  • Better Thermal Performance: Delivers up to 700 times better thermal efficiency than aluminum, significantly reducing heat transfer in material-to-material comparisons.
  • Better Thermal Break: Completely impervious to cold and heat, providing an unmatched thermal barrier that enhances overall energy efficiency.
  • Better Protection Against Condensation: Effectively prevents condensation buildup, reducing the risk of staining and corrosion often seen with traditional metal reinforcements.
  • Better Impact Testing: Demonstrates superior resistance to impact, offering greater durability and strength compared to other reinforcement products on the market.
InsulCore Insulated Foam Filling Technology: InsulCore is a proprietary foam-filling process designed to fill specific hollow cavities in the sash and mainframe of windows, creating an exceptional insulating barrier against thermal conductivity. This advanced technology significantly enhances the overall U-value of our windows, outperforming traditional hollow vinyl extrusions by over 9 R-values. InsulCore is an excellent value-added option that boosts energy efficiency, helping to reduce energy costs and improve the comfort of your home.
  • Superior Insulation: InsulCore foam-filling technology adds an extra insulating barrier within the window’s sash and mainframe, improving thermal performance.
  • Enhanced U-Value: By minimizing thermal conductivity, InsulCore significantly enhances the U-value of our windows, contributing to better overall energy efficiency.
  • High Performance: Outperforms standard hollow vinyl extrusions by more than 9 R-values, providing a noticeable improvement in insulation.
  • Cost-Effective Comfort: InsulCore helps lower energy costs, making your home more comfortable while enhancing energy efficiency without breaking the bank.

ENERGY EFFICIENT

Energy Efficiency

Energy Star – Our Window Man Double Hung windows are ENERGY STAR® labeled, ensuring you benefit from significantly lower energy bills and enhanced home comfort in every region. According to the U.S. Department of Energy, ENERGY STAR® rated windows excel in energy efficiency, based on estimates for a standard 2,000 sq. ft. single-story home with 300 sq. ft. of window area, utilizing gas heating and electric air conditioning. These savings are calculated using regional data and population-weighted energy use, alongside the Energy Information Administration’s average gas and electricity prices.

  • Double-paned, clear glass may not meet all local building codes.
  • Actual savings will vary based on your specific region and home characteristics. 

 

The National Fenestration Rating Council (NFRC) is a trusted non-profit organization that provides the only uniform, independent rating and labeling system for the energy performance of windows, doors, skylights, and related products. Their mission is to ensure fair, accurate, and reliable energy performance ratings, allowing consumers to make informed choices. The NFRC label on Window Man windows represents the overall thermal performance of each specific window tested, offering a clear understanding of its energy efficiency.

The NFRC label highlights key performance metrics, including the U-factor (where lower numbers indicate better insulation), Solar Heat Gain Coefficient (where lower values mean reduced heat gain), and Visible Transmittance (where higher values indicate better light transmission). Our NFRC thermal test results demonstrate that Window Man windows consistently outperform others, showcasing superior energy efficiency and thermal performance across all categories. The accompanying chart visually illustrates just how much better our windows perform compared to standard options, emphasizing our commitment to quality and energy efficiency.

AAMA and Structural Performance: The American Architectural Manufacturers Association (AAMA) is a respected voluntary organization that sets rigorous material performance standards for the window industry. Window Man windows are engineered to meet or exceed these demanding AAMA guidelines, ensuring exceptional quality and durability. Our windows undergo extensive testing to guarantee they can withstand various environmental conditions while maintaining structural integrity and energy efficiency.

The chart illustrates how Window Man windows outperform other styles in AAMA structural performance ratings, demonstrating superior strength, durability, and long-lasting efficiency. Our commitment to meeting and exceeding these stringent standards means you can trust that our windows will provide top-quality performance and reliability for years to come.

High Performance Glass Technology

Our Double Glazed Insulated Glass System features the patented Intercept® Spacer Technology, a unique U-channel design that reduces heat loss through the window. This one-piece, sealed spacer is stronger, better at retaining insulated gas, and helps prevent seal failures compared to conventional designs. The Intercept® spacer keeps window edges warmer, enhancing home comfort in the winter.

Our Triple Glazed Insulated Glass System uses the advanced Super Spacer® technology, a non-metal thermoset foam spacer with a dual seal, including NASA-approved acrylic adhesive and a hot melt butyl barrier. This design enhances energy efficiency, durability, condensation resistance, and comfort, making our windows last five times longer in tests compared to single-seal units.

Warm Spacer
