EXPERIENCE THE EVOLUTION OF THERMAL EFFICIENCY IN SOLID STEEL
Steel is five times more thermal resistant than aluminum, making it the ideal material for constructing the longest-lasting and best performing windows and doors. With Hope’s exclusive Thermal Evolution™ technology, all the intrinsic strengths of solid hot-rolled steel are maintained along with enhanced thermal efficiency, exceeding today’s most stringent thermal codes.
THERMAL EVOLUTION TECHNOLOGY: SIMPLY A SUPERIOR SOLUTION
Hope’s Thermal Evolution technology is a superior approach for creating a thermal break in fixed and operable time-tested solid hot-rolled steel windows and doors.
A Hope’s window or door equipped with Thermal Evolution technology features a fiber-reinforced polymer (FRP) isolator that is precision-machined to nest perfectly within Hope’s traditional hot-rolled solid steel frame profiles. This highly thermally resistant FRP isolator is structurally bonded to Hope’s steel window and door frames to create a powerfully strong and enduring composite construction that delivers impressive thermal efficiency and enhanced resistance to condensation.
DOESN’T SPLIT FRAMES
Manufacturers create thermal breaks in metal windows by splitting frames into exterior and interior sections, then reconnecting these sections with a polymer (plastic). However, this method, if applied to a Hope’s window, would significantly undermine its superior structural strength. And this would sacrifice a key reason why Hope’s windows are the most aesthetic, durable, and longest lasting. Instead, with Thermal Evolution technology, Hope’s traditional solid hot-rolled steel framing profiles remain completely intact the full depth of the window profile.
WINDOWS MADE WITH “STEEL PARTS” ARE NOT “SOLID HOT-ROLLED STEEL” WINDOWS
There’s no comparison in strength and durability between Hope’s solid hot-rolled steel windows and those that simply contain steel parts.
Hope’s concludes, after careful evaluation and testing, that the life-cycle and performance expectations synonymous with traditional hot-rolled steel windows and doors requires a solid steel web. Cladded and cold-rolled steel windows and doors do not meet these expectations.
ALL THE AESTHETIC AND STRUCTURAL BENEFITS OF SOLID HOT-ROLLED STEEL MAINTAINED
With patented Thermal Evolution technology, Hope’s is the only manufacturer of solid hot-rolled steel windows and doors with a thermal break. This means all the exquisite aesthetic potential of steel is maintained, including structural strength for virtually unlimited window size, extremely narrow frame dimensions and maximum glass area for the ultimate in clear views.
Hope’s windows and doors equipped with Thermal Evolution technology are ideal for new or retrofit construction of luxury residential, high-end commercial, cultural, institutional and historic preservation applications in virtually any color you can imagine.
Thermal Evolution technology accommodates True Divided Lite (TDL) or Simulated Divided Lite (SDL) muntin systems. Hope’s Power of 5 finishing system ensures that all Hope’s steel windows and doors last longer than any other available, even under the most extreme environmental conditions.

Refer to product specific specifications for design performance data.
The National Fenestration Rating Council® (NFRC), the U.S. leader in energy performance rating and certification programs for the window and door industry, ensures consistent third-party testing criteria with public access to product testing results.
Hope’s Landmark175™ Series with Thermal Evolution technology achieved impressive testing results from NFRC:
|U-factor as low as:||CR rating as high as:|
|Thermal tested, listed, and certified in accordance with NFRC-100, NFRC-200, and NFRC-300. U-value is a measure of heat loss with lower numbers indicating better insulating properties. CR is a measure of condensation resistance with higher numbers representing more resistance to the formation of condensation.|
It is also important to understand that thermal performance varies depending upon glass make-up and other variables of a window. For example, triple-paned windows will produce an even better U-factor than traditional single pane of glass.
