Prefabricated modular construction technologies continue to advance solutions for diverse sectors worldwide. As a leading innovator of pre-engineered steel building systems, Lida Group strives to expand the applications and sustainability benefits of their globally deployed construction solutions.

This white paper introduces new structural panel and cladding innovations recently developed by Lida Group research and engineering teams. These innovations further optimize the company’s proprietary reusable prefabricated construction approach to meet evolving structural and environmental performance requirements.

Two new versatile panel products – the ReWall structural sandwich panel and Therma Clad insulated metal wall panel – are profiled. Their design, material composition, manufacturing process and technical specifications are detailed. Initial building prototype applications highlight expanded opportunities across commercial, industrial and specialized agricultural sectors.

By advancing modular construction technologies, Lida Group aims to provide clients more durable, efficient and sustainable building solutions. The new panel innovations introduced contribute to this vision through optimized prefabricated structural and envelope designs supporting global development priorities.

ReWall Structural Sandwich Panel

The ReWall panel is a lightweight load-bearing composite composed of galvanized steel skins bonded to a insulating polyurethane foam core. Several proprietary innovations set it apart:

– Skin thickness of 0.4mm for robustness yet 25% lighter material usage versus conventional pre-cut panels.

– CFC-free foam core laminated under high heat/pressure for enhanced insulation and strength-to-weight ratio.

– Roll-form manufacturing enabling on-demand panel cutting to maximize material yields.

– Enhanced embossing on steel surfaces provides improved adhesion during lamination.

Testing confirms the ReWall panel possesses equivalent or better structural capacity to alternatives up to 40% heavier. Its insulating core achieves an industry-leading R-value of 5.4 per inch thickness. Smooth panel surfaces require no additional fireproofing or finishes.

Prototyped building applications include industrial cold storage facilities in Southeast Asia and agro-processing warehouses in East Africa. Prefabricated walls, floors and roofs assembled in 40-60% less time on-site than traditional methods. Combined with 30% materials cost savings, simple payback is estimated at 2-3 years.

ReWall elevates prefabricated modular construction performance by optimizing steel and insulation usage. Its availability as a cost-competitive reusable building panel expands multi-sector applications sustainably.

ThermaClad Insulated Metal Wall Panel

The ThermaClad panel features Lida Group’s first fully insulated architectural metal cladding solution. Highly versatile applications include:

– Outer walls, mansard roofs and dormers utilizing a concealed fastener pre-finished insulated panel.

– Splash zone and soffit applications of the same panel with additional primed aluminum coil exterior.

Some key innovations of the ThermaClad panel include:

– Thicker 0.5mm Galvalume steel facers encapsulating rigid polyisocyanurate foam insulation.

– Double-folded seamed joints achieving air/water tightness equal to stick-built installation quality.

– Proprietary manufacturing allowing up to 9R insulating values in standard panel thickness.

– Non-combustible interior and exterior finish options meeting global code compliance.

Prototype facilities constructed include commercial office towers in Australia utilizing ThermaClad for rainscreen-style outer walls. Testing found the panels reduced energy costs up to 15% annually compared to traditional steel cladding under similar climates.

By providing a complete reusable envelope solution, ThermaClad expands modular construction potential into high-performance commercial and institutional markets worldwide.

Prefabricated Modular Construction

Prefabricated modular construction helps address challenges including: material and labor shortages; rising costs; schedule delays; quality control; site waste generation and safety risks. The innovations highlighted demonstrate Lida Group’s ongoing dedication to optimizing their construction system performance.

Key advantages of the new panel products include:

– Higher strength-to-weight ratios for reduced foundations and material transportation needs

– Precut-to-size manufacturing enabling maximum material yields and flexibility

– Improved energy efficiency lowering total building lifecycle costs

– Faster assembly times with fewer skilled laborers required on-site

– Multi-sector solutions through expanded envelope and structural applications

– Higher reused material recoverability at building end-of-life

– More durable and sustainable buildings using optimized materials

As modular construction adoption accelerates globally, innovations supporting continued improvements will remain vital. Evidence presented suggests Lida Group’s new panel innovations offer clients optimized prefabricated building solutions at expanded scales.
