FTC Cracks Down on Windows’ Energy-Efficiency Claims
According to the FTC, Gorell Enterprises, which manufactures windows with the Thermal Master III glass system and other lines, lacked a reasonable basis for claiming that consumers who replaced existing windows with Thermal Master III windows were likely to achieve residential energy savings of 40% or save 40% on home heating and cooling costs.
It says Long Fence & Home’s claims that the Serious Energy Quantum 2 windows with SuperPak glass that Long Windows distributes and installs made “unsubstantiated” claims, including a 50% energy savings guarantee.
Serious Energy, the agency says, provided its dealers with marketing materials that included claims such as, "Guaranteed to reduce your heating and cooling use by up to 49%." The savings claims for the advertised windows were unsubstantiated, the FTC says.
THV Holdings' telemarketing sales scripts represented that its replacement windows would "cut energy bills in half" and that homeowners could expect to see a 35% to 55% reduction in monthly energy bills, among other claims. The agency charged that THV lacked a reasonable basis for the savings claims.
And finally, Winchester Industries, which manufactures the Bristol windows, claimed that consumers would "reduce energy costs by 47%" and that "the triple-paned design of some replacement windows, such as Bristol windows, can also produce energy savings of up to 50% a year." The FTC charged that Winchester lacked a reasonable basis for making its energy savings claims for its windows.
The glass is relatively easy, its the frame that is hard to get the higher values from.
A lot of window manufactures will quote the higher center of glass values rather than the lesser whole window values.
