A new Isokorb structural thermal break for concrete parapets employs Glass Fiber Reinforced Polymer bars to further reduce thermal conductivity between external and heated internal concrete structures, while simplifying installation.
The pursuit of elegant building enclosure design is ever-growing, particularly for aluminum-framed curtain wall systems. Where these curtain wall systems transition to horizontal roof systems, designers have long sought to minimize the visual impact of these conditions by subtly concealing them.
The profile of specific components, their configuration or sequencing, can vary with the roof system, climatic differences, and regional or area practices.
One of the ways the design, engineering and construction teams met the City of Vancouver’s new stringent energy requirements was by using structural thermal breaks to prevent thermal bridging at balconies, eyebrows, parapets and planter walls.
The parapet is so much more than the intersection of roof and wall. It’s also the junction where building aesthetics meets structural performance, air and moisture management, energy efficiency, construction trade sequencing and operational maintenance.
Section 1503.3 Coping: Parapet walls shall be properly coped with noncombustible, weatherproof materials of a width no less than the thickness of the parapet wall.
