Technology Description:

Triton Systems will develop and demonstrate a high efficiency windowpane system that will encourage retrofitting of single-pane windows. Triton's Multifunctional Glazing System (MGS) will potentially provide a better balance of performance with cost and weight versus double-pane insulated glass units. The system combines a nanoparticle-polymer composite film with an insulating layer of a porous material filled with air, to provide thermal insulation. The team will enhance the pane’s durability by incorporating a nanocomposite edge seal. The thickness of the MGS will be less than ¼ inch, ensuring its compatibility with most single-pane window sashes as a direct glazing replacement.

Potential Impact:

If successful, Triton’s innovations will enable energy-efficient retrofits for the substantial remaining stock of single-pane windows in the United States. Retrofitting single-pane windows could produce significant environmental and economic benefits. By consuming less electricity, natural gas, and/or heating oil to warm a building, these technologies could help avoid greenhouse gas emissions associated with these energy sources. Moreover, these technologies could help reduce building energy consumption and save money for homeowners and businesses. Consumers adopting these retrofits could also benefit from improved window performance, including greater comfort and reduced condensation in cold weather and improved.
