ET25SWG0001 - Thin Triple Pane Windows

This project aims to research and evaluate the market for thin triple-pane windows and window panel add-ons in residential and multi-family buildings. The study will focus on the current use of industry-standard incumbent technology of double and single-pane windows and assess the potential benefits of adopting thin triple-pane windows and panel add-ons. Thin triple-pane windows, which have the same dimensions as double-pane windows with only a marginal increase in weight, provide the same R-value as traditional thickness triple-pane windows, an increase from the incumbent. This design minimizes the increased costs associated with installation in new or retrofit builds, as well as reducing shipping costs. Additionally, window panel add-ons offer an extra layer of insulation, reducing heat transfer and easing the load on HVAC systems without increasing utilization costs. These add-ons are custom sized for each window, ensuring flexibility and ease of installation.

By reducing heat transfer, these products lower HVAC system loads and associated utility bills, offering significant cost savings. The lightweight design of panel add-ons further reduces manufacturing, shipping, and installation costs. Thin triple-pane windows occupy the same market niche as double-pane windows and can be used in the same manner, including opening and closing. Several manufacturers currently produce and sell thin triple-pane windows and panel add-ons. The goal of this agile project is a market assessment to help justify the need for a medium sized modeling project which can be used to update the statewide measure package that is currently being developed.
