WonderWindows new construction windows got their start by doing retrofits in Vermont under a USDA Small Business Innovation Research grant. Rock Point High School in Burlington, VT retrofitted 104 windows, saving over $569 a year in this historic 1887 building with inefficient natural gas fired boilers and radiators. Savings in kerosene or fuel-oil furnaces or boilers could be 2.3 times greater.

WonderWindow in the Community

WonderWindow worked with student volunteers from St. Michael’s College in Colchester, VT installing WonderWindows on the mobile homes of low income seniors. 147 total window retrofits on 14 individual homes yield up to $3.90/sf of calculated annual energy savings for these kerosene-heated homes: one client is saving as much as $500.
