Warmframe® is a brand new word to the Curtain Wall Industry. Generally speaking, Warmframe® is a novel and high performance thermal break technology for building envelopes.

Since the thermal conductivities of the metal frames of facades are usually quite high, for example, the thermal conductivity of aluminum alloy is 160.00 W/(m∙K), thermal break materials with much lower thermal conductivities are usually placed in between the metal frames to provide better thermal performance. The traditional thermal breaks include: polyamide (nylon), polyurethane (PU), EPDM and etc. The thermal conductivities of these materials are about 0.25 W/(m∙K), which is much lower than the metals. However, the thermal conductivity of the High Performance Thermal Break Blanket is typically no larger than 0.019 W/(m∙K), which is less than one tenth of the traditional materials. In another words, the efficiency of the thermal loss thru the High Performance Thermal Break Blanket is more than 10 times better.

Warmframe® technology is to mechanically fix the High Performance Thermal Break Blanket, such as Warmframe® 1000 in between the interior and exterior metals. If properly designed, it may be combined smoothly with the existing facade system and maximized its advantages, such as thin profile, super high thermal performance, excellent water repellent and easy processing. Should Warmframe® technology is adopted, it may contribute to reduce the thermal transmittance of curtain wall frames (U_f) significantly, and improve the overall thermal transmittance of curtain wall (U_cw) eventually. Meanwhile, the condensation risks happen thru the frames are minimized to the lowest level. Warmframe® simplifies the detail of thermal break and encourages mechanical fixing, which resolves most of the concerns regarding structural safety.
