Solar Heat Gain by the
National Fenestration
Rating Council (NFRC).
Fiberglass windows are
among the most energy
efficient windows available
today. Less energy is
required to manufacture
fiberglass windows than
other window materials,
and little waste is produced
during the manufacturing
process. Fiberglass is also
valued for its longevity
and ability to conserve
energy even in extreme
climate conditions.
Fiberglass-clad. The choice that’s energy efficient.
Weather Shield Fiberglass-clad premium wood windows are among the most energy efficient windows available today. The virtually indestructible nature of fiberglass makes it a superior fenestration choice, providing long term savings due to little or no maintenance costs and lower energy bills. The low U-factor and Solar Heat Gain Coefficient of fiberglass also meets or exceeds the requirements of the 2009 ARRA Energy Tax Credit, giving homeowners even greater savings towards energy efficient home improvements.
Durable Fiberglass provides the ultimate combination of increased strength, energy efficiency and structural capabilities. Fiberglass remains unchanged over years of performing in extreme temperatures. This hard-wearing material is also impervious to termites and other pests, scratch and dent resistant and does not corrode or rot, making it an ideal solution for coastal applications or other harsh environments.
Premium wood interiors give our Fiberglass-clad windows a refined appearance that is uncommon among other fiberglass products. Weather Shield Fiberglass-clad premium wood windows offer an array of exterior color choices, pre-finished interior wood choices, and the design flexibility desired by homeowners today.
Zo-e shield™. Built better to reduce energy.
Zo-e shield™ is unlike any glass system in the world. It
delivers the most energy efficient result you can achieve
from the newest glazing technologies. And that means
unparalleled performance in lowering energy use and utility bills, preventing sun damage and
protecting the environment. Our exclusive Zo-e Shield glazing systems feature multiple layers
of Low-E coatings that filter
out the light spectrum’s heat transmission to optimize the sun’s
heat and a home’s heating/cooling systems. Homeowners can save thousands of dollars in
energy costs during the lifetime of the home.
Energy Saving Where You Live

Installing Zo·e·shield windows saves you money over clear double-paned wood windows. Your estimated savings will vary from region to region based on home heating and cooling costs. Variations are generally greatest in regions with hot summers, cold winters or both.
The estimated savings for a typical home, from replacing double-paned wood windows with Zo·e·shield windows, are significant in all regions of the country and can range from 15% to 30% a year.† To learn how much you can save, go to zoeshield.com and click on the “save money” icon.
† Savings are relative to a double-pane clear glass window. Based on a national average size house (2,300 sq. ft., 2-story), with 18% window to floor area ratio, 15% shade usage, gas heat and electric air conditioning. Long term national average energyprices of $1 per therm for natural gas and $0.09 per kWh electric. Actual savings will vary by climate region, house type, homeowner operational characteristics, and local energy prices.
