Thermal performance
Incorporated in our designs is a thermal barrier to ensure that the inside elements of the
curtain wall remain at a constant temperature relative to the interior temperature of the
building. This is achieved by separating the outer elements and the inner elements with a
continuous extruded thermal brake. The need for a proper thermal barrier are as
follows :
1. To ensure that the temperature of all elements that
are located on the interior side of the air seal / vapour barrier line is above the dew
point at the specified conditions of humidity and temperature ;
2. To achieve a warm cavity around the edge of the sealed glass unit by locating the
thermal barrier at the outermost face of it.

Considering the type of glazing specified on most
projects, it is essential that, for good performance of the systems, the incorporation and
location of the thermal barrier be such that it will assure an acceptable temperature
differential between the middle and perimeter of the glass units, minimizing the
probability of breakage due to thermal shock. This is accomplished in our designs.
