LEWIS® Deck: Engineered Flooring Solutions That Meet the Highest Standards
In the world of modern construction, selecting the right flooring system is critical—not only for structural performance but also for comfort, safety, and long-term durability. LEWIS® Deck, composite floor system, is designed to meet the increasingly demanding criteria of today’s residential, commercial, and modular building projects.
Whether you are building multi-family homes, hotels, healthcare facilities, or modular units, LEWIS® Deck offers a reliable and tested solution that combines structural efficiency, acoustic comfort, fire resistance, and thermal adaptability.
1. No Temporary Propping – Simpler and Faster Installation
A major advantage of the LEWIS® Deck system is that it allows for installation without the need for temporary propping on standard spans with appropriate screed thickness. This not only simplifies site logistics but also accelerates the construction timeline, making it ideal for projects where speed and efficiency are essential.
By eliminating the need for support props during the curing phase, LEWIS® Deck enhances safety on-site and reduces labor and material costs associated with formwork or shoring.
2. Exceptional Load-Bearing Performance
LEWIS® Deck systems are engineered to handle high structural loads, exceeding typical design requirements for both dead and live loads.
- • Dead load capacity is optimized when used with fine-grade or liquid screeds, ensuring a stable platform for further finishes.
- • Live load resistance comfortably exceeds the standard requirement for residential and commercial flooring, accommodating heavy usage areas and flexible occupancy types.
With high strength-to-weight efficiency, LEWIS® Deck offers peace of mind and flexibility for architects and engineers designing multi-storey and mixed-use buildings.
3. Superior Acoustic Insulation – Designed for Sound Comfort
Noise control is a top priority in shared buildings, and LEWIS® Deck systems are designed to significantly reduce both impact and airborne sound transmission. When used in combination with resilient strips and proper insulation, the system meets and surpasses the commonly required standards for acoustic performance.
- • Impact sound insulation (IIC): Helps reduce footfall and mechanical impact sounds transmitted through the structure upto 52 dB with MTA 5 Strip
- • Airborne sound insulation (STC): Minimizes sound transfer between rooms or units, ensuring privacy and comfort upto 71dB with MTA 5 Strip
These properties make LEWIS® Deck ideal for applications such as hotels, apartments, student housing, and office buildings where acoustic control is vital.
4. Fire Resistance from Floor to Ceiling
Safety and compliance are non-negotiable in today’s building regulations. LEWIS® Deck systems can be integrated with certified ceiling systems to deliver up to 120 minutes of fire resistance, from the underside of the ceiling to the top of the screed.
This makes the system well-suited for buildings with stringent fire performance requirements, including high-rise structures, hospitals, schools, and institutional facilities. Fire-tested configurations ensure safety for occupants and help meet regional fire code standards.
5. Thermal Performance – Adaptable to Project Needs
While LEWIS® Deck is primarily a structural and acoustic floor system, it also supports energy-efficient design. Thermal resistance targets can be achieved through the integration of insulation within the floor build-up, especially in the plenum or void space.
By selecting the appropriate thickness and conductivity of insulation materials, U-values can be fine-tuned to meet local energy codes and green building certifications.
For optimal results:
- • Use 140 mm insulation to satisfy basic acoustic needs.
- • Increase to 170 mm or more for enhanced thermal performance, especially in colder climates or energy-efficient buildings
6. Slim Profile – Ideal for Lightweight and Modular Construction
The LEWIS® system’s low-profile design allows for reduced floor build-up without compromising strength or performance. This makes it a perfect solution for:
- • Renovation projects where headroom is limited
- • Timber or light steel frame structures
- • Modular and prefabricated construction
- • Mezzanines and loft extensions
The integration with steel or PFC joists further enhances its compatibility with hybrid structural systems.
7. Materials and Components
A typical LEWIS® Deck flooring system includes:
- • LEWIS® steel decking (0.5 mm)
- • Fine-grade concrete ≥ C30/37 or liquid screed ≥ C30/F4
- • Resilient acoustic strips (e.g., MTA 15/7)
- • High-performance thermal/acoustic insulation (≥140 mm or more as needed)
- • Compatible ceiling system for fire-rated assemblies
Every component works together to form a high-performance composite floor that is robust, quiet, safe, and compliant.
The Smart Choice for High-Performance Floors
LEWIS® Deck stands out as a smart, multi-functional flooring system for today’s construction challenges. Its performance across structure, sound, fire, and thermal criteria makes it an attractive choice for builders, architects, and developers looking to meet compliance standards without complexity.
At Zintex, we believe in supporting the industry with solutions that are engineered for longevity, safety, and performance. LEWIS® Deck is one such solution that offers proven reliability with the flexibility to adapt to various project needs.
