Integrative Systems
Technology, New Products and Integrative Systems
ELFI systems combine structural, load-bearing steel framing and Expanded Polystyrene (EPS) foam insulation into one product (stand-alone building envelope or as a comprehensive system base). With energy-efficiency foremost, ELFI’s integrative component-based, system of products, methods and processes are state-of-the-art in the green-building construction market, and ELFI Systems are integratable with all efficiency-focused advanced technologies, products and systems, as well as, all conventional methods when necessary.
- ELFI exterior wall and roofing system is of light-gauge steel with high-performance, load-bearing profiles and integrated with light-gauge steel floor joist systems and light-gauge steel roofing trusses. This, in turn, makes:
- The entire structure lighter (7-12 times) compared to block (CMU) construction.
- Lowers, lightens demands on concrete foundation by approximately one-third.
- The entire exterior envelope is of non-combustive materials.
- Our steel is 40-70% recycled content, and after the life of a structure is 100% recyclable.
- Lightweight means lower transportation costs, easier and safer working environment, and no need for heavy lifting equipment or specialty trades.
- Light-gauge steel floor joists are assembled with metal pan (same i-v applies here) and lightweight, self-leveling cementitious products. In a four-season climate these floors could be embedded with radiant, in-floor heating (highly energy-efficient and the most comfortable).
- Light-gauge steel roofing trusses could be designed for extreme conditions (hurricanes, tornados, heavy winds, micro-bursts, brush and fire resistance ratings, earthquake…).
- Over the years ELFI exterior envelopes have proven 40-60% reduction in energy needs for HVAC. This could be further reduced by solar panels installations, as one example: ELFI utilizes solar panels in two ways – producing, storing and consuming DC electric power and heating water for potable use and enhancing heating capabilities.
- There are several finishing products which further simplify, enhance and make the building process faster and more economical. Additionally, exterior finishes such as concrete stain is high quality, a durable material, and facilitates endless desirable aesthetics. With roofing, new, advanced spray-on roofing finishes provide a long lifespan, are toxic, and non-flammable. These are only a couple of examples of ELFI flexibility, integrate-ability, efficiencies and high-performance.
ELFI materials and components are established and sustainable construction items. ELFI configuration, integration, process and methodology provide high-performance for every project, from basic design to net/near-zero to absolute zero-energy structures for parameters of any scope, every time.
