The global construction sector is undergoing a rapid technological evolution. As energy regulations tighten, environmental requirements grow stricter, and project timelines shorten, EPC contractors, project architects, and real estate developers are shifting from traditional heavy on-site masonry to engineered modular building panels. These structural sandwich panels provide structural integrity, architectural versatility, and class-leading thermal insulation within a single integrated package.
Prefabricated modular panels reduce construction schedules by up to 50%. The tongue-and-groove interlocking profiles facilitate quick installations without the need for intensive local labor or weather-delayed concrete pouring.
Featuring cores made of Polyisocyanurate (PIR), Rock Wool, and Polyurethane (PU), these systems achieve excellent thermal values (U-values below 0.15 W/m²K), keeping HVAC loads low throughout the building lifecycle.
Our panels are manufactured to comply with strict ASTM, EN, and GB fire performance classifications, including Class A non-combustibility for Rock Wool cores and self-extinguishing parameters for custom PIR matrices.
Understanding insulation profiles, fire dynamics, and mechanical performance values is crucial for selection. The table below outlines standard performance metrics across different modular panel core layers.
| Insulation Core Type | Thermal Conductivity (λ - W/m·K) | Fire Classification (EN 13501-1) | Density Range (kg/m³) | Primary Industrial Application |
|---|---|---|---|---|
| PIR (Polyisocyanurate) | 0.019 - 0.022 | B-s1, d0 (Fire Retardant) | 38 - 42 | Cold Storage Facilities, Automated Logistic Hubs |
| Rock Wool (Mineral Fiber) | 0.035 - 0.040 | A1 / A2 (Non-Combustible) | 80 - 120 | High-Risk Processing Plants, Fire-Rated Partitions |
| PU (Polyurethane - PUR) | 0.022 - 0.024 | B-s2, d0 | 35 - 40 | Agricultural Sheds, Modular Residential Panels |
| EPS (Expanded Polystyrene) | 0.033 - 0.038 | B-s3, d0 / E | 15 - 25 | Budget Modular Enclosures, Dry Cargo Sheds |
| XPS (Extruded Polystyrene) | 0.029 - 0.032 | B-s2, d0 | 32 - 38 | Heavy-Load Cold Room Flooring, Sub-grade Insulation |
As the global supply chain faces material bottlenecks and logistics volatility, sourcing modular building panels from an advanced manufacturing plant ensures stability. Our production facilities utilize Industry 4.0 automation to deliver consistent quality and cost efficiency.
Our continuous double-belt manufacturing systems ensure uniform distribution of the insulation core, eliminating internal voids. This gives the panels high resistance to delamination under wind loads and changes in temperature.
We use premium galvanized and pre-painted steel sheets (PPGI/PPGL) with coatings like PVDF, HDP, and PE. This provides corrosion protection, making the panels suitable for chemical plants, coastal warehouses, and food processing facilities.
Our advanced CNC milling systems create precise tongue-and-groove joint profiles, including double-groove options. These joints prevent air and moisture infiltration, helping maintain strict internal temperatures.

Designed with airtight seal details and options like stainless steel or anti-static surfaces, these cleanroom panel assemblies maintain positive pressure differentials and resist aggressive cleanroom sanitizing washdowns.
Engineered for high wind load performance and structural span capacity. These wall and roof systems reduce secondary structural framing steel weight, lowering total construction cost per square meter.
Integrating aesthetic exterior finishes like stone, marble, and wood grain textured facades with an insulated composite core. This offers residential-grade thermal values with rapid, modular structural build times.
Expert insights on structural, thermal, and regulatory specifications for modular panel building systems.
With high-quality hot-dip galvanized substrates (Z275/AZ150) and PVDF/HDP paint systems, our modular building panels have a designed mechanical and structural service life exceeding 25 years under standard atmospheric exposures.
PIR (Polyisocyanurate) is an advanced version of polyurethane that offers improved thermal resistance and fire performance. It features a ring-like chemical structure that resists high temperatures, helping meet strict fire safety regulations.
Our interlocking panels feature double-tongue-and-groove joint options with built-in PVC gaskets. This design prevents thermal bridging, limits air leakage, and maintains cleanroom environment requirements.
Yes. For harsh environments like coastal factories, chemical processing plants, or agricultural barns, we provide customized options such as stainless steel liners (Grade 304 or 316) or high-durability coatings to prevent chemical and moisture damage.
