Hope’s Introduces Thermal Evolution Technology for Hot-Rolled, Solid Steel Windows

Hope’s® introduces Thermal Evolution™Technology, a breakthrough solution for hot-rolled, solid steel windows to meet increasingly stringent energy efficiency standards.

With significantly improved U-factors and condensation resistance, the Hope’s technology achieves a thermal break for steel windows while retaining their superior qualities that enable endless design possibilities.

The Hope’s Thermal Evolution Technology–U.S. Patent No. 8484902 for operable windows and a patent pending for fixed windows–employs fiberglass reinforced polymer (FRP) liners that are structurally bonded to fully-welded, hot-rolled, solid steel profiles.

The first product line to feature the Thermal Evolution Technology is the Hope’s Landmark175™ Series which achieved impressive testing results from the National Fenestration Rating Council® (NFRC): a 0.170 U-factor during a series of tests completed in May 2013; and a 0.25 U-factor during tests finished in October 2013. In addition, the new Thermal Evolution Technology achieves a Condensation Resistance (CR) ratings of 49 for fixed windows and 36 for operable, according to NFRC testing.

“Hope’s hot-rolled steel windows and doors have been the benchmark for architects for over 100 years,” says Randy Manitta, CEO/President of Hope’s. “We were determined to address the tougher energy codes while preserving the core product attributes Hope’s is known for: strength, durability and narrow sightlines. The design of the conventional thermal break window, used by other window manufacturers, splits the window profile which compromises the very essence of a steel window. Hope’s FRP liner technology retains the integrity of a steel window.”

The strength of steel windows allows for minimized frame profiles and maximized glass area, offering the best views. The Hope’s steel windows are a favorite of architects and interior designers because they are custom designed and handcrafted to attain the widest range of design visions–with virtually unlimited shapes, sizes, finishes and profiles. Thermal Evolution Technology can accommodate True Divided Lite (TDL) or Simulated Divided Lite (SDL) muntin systems. Hope’s advanced coating process ensures that all Hope’s steel windows last longer than any other available, even under the most extreme environmental conditions.
