Together, these innovations streamline every stage of on-site assembly, from unloading to final finishing, drastically reducing project timelines.

2.1 Integrated Panel Design: All-in-One Construction

Unlike traditional construction, which requires separate installation of framing, insulation, cladding, and interior finishes, easy install sandwich panels combine all these functions into a single prefabricated component. Each panel features two high-strength outer facings (typically galvanized steel or aluminum) bonded to a core insulation material (rock wool, polyurethane/PU, or expanded polystyrene/EPS), with factory-finished exteriors and interiors. This integration eliminates 80% of on-site workflow steps—there is no need for on-site plastering, painting, or insulation installation, as the panels arrive ready to assemble.

The lightweight nature of the panels further accelerates installation. A standard 1.2m×2.4m sandwich panel weighs just 12–22 kg/m², depending on the core material—30% lighter than traditional brick-and-mortar walls or concrete slabs. This allows two laborers to manually handle and install panels, eliminating the need for heavy machinery such as cranes for most residential-scale projects. For example, a 100㎡ prefab house requires only 2–3 truckloads of panels, and the entire structural assembly can be completed by a team of 3–4 general laborers in 3–7 days, compared to 2–3 months for traditional construction .

2.2 Intuitive Connection Systems: Tool-Free, Precision Assembly

The defining feature of easy install sandwich panels is their proprietary connection systems, which enable fast, secure assembly without specialized skills or equipment. Two core connection technologies dominate this space, each optimized for different project scales and requirements:

Cam-Lock Joints: Designed for modular prefab houses, cam-lock joints are integrated into the panel edges and structural frames. With a simple twist, the joints engage to create a tight, secure bond between panels and the frame, eliminating the need for bolts or welding. This system reduces panel installation time by 70% compared to bolted connections, with each joint requiring just 10–15 seconds to fasten. The joints are engineered to maintain structural integrity under extreme conditions, withstanding wind loads of up to 120 km/h and seismic activity of magnitude 7.

Tongue-and-Groove Seams: For wall and roof panels, precision-machined tongue-and-groove edges allow panels to slot together seamlessly. Pre-installed weatherstripping within the seams creates an airtight, waterproof seal, eliminating the need for on-site caulking or sealing work. This system enables laborers to install up to 80 m² of panels per day—four times faster than traditional framing and cladding methods. The standardized design ensures consistent alignment, reducing errors and rework to near zero.

Both systems are complemented by clear labeling and assembly guides, ensuring that even laborers with minimal training can complete installation efficiently. This accessibility expands the labor pool and further accelerates project timelines, a critical advantage in regions facing skilled labor shortages.
