Reliance™ is a thermally broken, zone glazed, pressure-equalized curtain wall system offering both captured and structural silicone glazed vertical mullions with multiple system depths and glazing infill options.


To meet demands for more stringent thermal performance criteria, the Reliance™-HTC Curtain Wall System was developed by Oldcastle BuildingEnvelope®.


Reliance™-SS is an outside glazed screw spline, split vertical mullion version of the popular Reliance™ Curtain Wall, offering captured and structural silicone glazed vertical mullions with multiple system depths to meet ever growing demands for less field labor.

Reliance™-SS Enhancements

Our Reliance-SS Curtain Wall system is an outside glazed, front set pressure wall curtain wall system that offers screw spline assembly of frames and the ability to shop seal the frame before shipping to the project site. Available in both 6" and 7-¼" depths, using either captured or structural silicon glazed verticals, this wall system now features several enhancements.


Energy efficiency has become a critical part of the design process in modern construction. With this in mind, Oldcastle BuildingEnvelope® has developed the Reliance™-TC Thermal Composite Pressure Wall Curtain Wall System.

Reliance™-TC IG

To complement the popular Reliance™ Curtain Wall platform, Oldcastle BuildingEnvelope™ has developed a thermal composite inside glazed curtain wall system, Reliance™-TC IG.
