Thermal performance of novel frame-integrated unitised curtain wall

Framing of unitized curtain walls is dimensioned to carry wind load without taking advantage of potential composite contribution of glass. Subsequently, it is unnecessarily deep, occupying valuable space, and protrudes to the inside, causing visual disruption. Moreover, it is generally made of high...
