Oldcastle Building Envelope Co., Ltd. (OBE), a globally renowned provider of building enclosure system solutions, has recently officially launched the Reliance TC SS (Thermal Control Spiral Spline) new high-temperature spiral spline curtain wall system. This product is based on OBE's mature and reliable Reliance curtain wall platform for iterative upgrades, focusing on the global trend of building energy efficiency upgrades. It integrates top-notch thermal performance, industrial manufacturing efficiency, and facade design flexibility, providing more competitive enclosure solutions for commercial buildings, high-end public buildings, and other projects.

The current global building energy efficiency standards continue to tighten, with high insulation and low energy consumption becoming the core requirements for curtain wall systems. Reliance TC SS strictly adapts to the stringent specifications of IECC climate zones 4-8 and can meet the constantly upgrading energy-saving stretching standards, maintaining stable performance even in cold and high-altitude weather conditions with large temperature differences. The system breakthrough adopts thin three-layer insulated glass units (IGUs), achieving excellent U-values as low as 0.19 without increasing the overall depth of the curtain wall system. With a lightweight structure, it achieves top-level insulation and thermal insulation effects, helping the project easily meet strict energy standards without sacrificing building aesthetics and installation efficiency.

In terms of structural design and construction adaptation, Reliance TC SS relies on spiral spline assembly structure, greatly simplifying the factory prefabrication process. Mature construction methods are used for on-site installation, effectively improving construction efficiency and shortening the construction period. The system is compatible with diverse glass configurations and can adapt to 1-inch standard insulated glass and 1-inch high-end thin three-layer insulated glass, achieving flexible performance expansion within the same system and meeting personalized needs of different projects. Relying on the integrated supply advantage of OBE glass and frame, the entire process of project coordination from specification formulation, deepening design to on-site installation is smoother, and system compatibility and overall quality are more guaranteed.

Julie Schessler, Product Manager of Oldcastle BuildingEnvelope, stated that Reliance TC SS accurately responds to the development direction of the curtain wall industry, integrating high thermal performance with the high efficiency of spiral spline structures, helping design, development, and construction teams achieve a win-win situation between energy-saving goals and building effects without adding additional complexity when dealing with increasing performance demands.

This new product release further improves the OBE high-performance curtain wall product matrix, providing more advanced and reliable facade technology support for global green building and low-carbon landmark projects, and promoting the continuous upgrading of building enclosure systems towards high efficiency, energy efficiency, and ease of implementation.
