As extensions of interior floor slabs, traditional balcony slabs conduct heat from the warm building interior into cold exterior environment with the unwanted efficiency of enormous cooling fins. In addition to wasting heat, chilling the interior side of the slab in today's air-tight, higher-humidity buildings can quickly form condensation, causing mold to grow and become airborne months or years before it becomes visible on room surfaces, exposing the developer to significant remediation and personal injury liability.
Isokorb® structural thermal breaks from Schöck can eliminate this problem by providing structural support equivalent to traditional floor slab extensions, and simultaneously insulating the interior floor slab from the exterior balcony slab at the building envelope.
The high-strength cast assembly cuts energy waste by up to 90% at the penetration, and up to 14% for the building overall — passively for the life of the building. Eliminating cold interior slabs additionally prevents condensation and mold formation, while pleasing tenants and owners with interior floors that are up to 27°F / 15°C warmer adjacent to balcony doors and exterior walls.
Whether your balconies are cantilevered or supported, recessed or rounded, Schöck offers the most comprehensive range of structural thermal break products to prevent thermal bridging at your balcony connections.
