Site dormitory panels are A1 fire-rated rock wool sandwich panel systems engineered for construction site dormitories, labor camps, and worker accommodation housing large numbers of occupants in close quarters. The outer skins use color-coated galvanized steel sheet at 0.5mm thickness, providing non-combustible facings that add an additional layer of protection against fire spread across the dormitory envelope.
The rock wool core delivers A1 non-combustible performance at density of 80-120 kg/m³, with a melting point of 1600°C that far exceeds conventional fire temperatures. Thermal conductivity of 0.040-0.045 W/(m·K) provides reliable insulation, while the inorganic silicate fiber structure releases no toxic smoke during fire exposure, achieving fire resistance of EI30 at 50mm thickness and EI120+ at 100mm thickness per EN 13501 and GB 8624 testing.
Standard total panel thickness ranges from 50mm to 150mm, with effective widths of 950mm and 1150mm and lengths customized to dormitory module dimensions. Skins are joined to the core through continuous high-pressure lamination, with tongue-and-groove or concealed-clip joint profiles that prevent thermal bridging and maintain fire compartment integrity across the wall and roof envelope.
These site dormitory panels serve construction site accommodation, worker camps, modular hospitals, resettlement housing, and emergency relief shelters. They comply with GB 50720 mandatory A-grade core requirements for occupant buildings, achieving wind load resistance of 0.6-1.5 kPa, floor live load capacity of 2.0-2.5 kN/m², and structural design service life of 15+ years for semi-permanent deployment.

Site Dormitory Panel Buying Guide & FAQ
Selecting the right site dormitory panel requires understanding fire safety classifications, core density, structural load ratings, and compliance with occupant building codes. This guide answers the most common questions from construction contractors, camp housing providers, and humanitarian project managers evaluating rock wool sandwich panels for worker accommodation and dormitory deployments.
1. Why is rock wool the mandatory core for site dormitory panels?
Rock wool is the mandatory core for occupant dormitory buildings because it achieves A1 non-combustible classification per GB 8624, with a melting point of 1600°C that prevents structural collapse during fire. GB 50720 explicitly requires A-grade non-combustible core materials for dormitory and office buildings on construction sites, making rock wool the only compliant choice for legal occupant accommodation alongside galvanized steel facings.
2. What fire resistance ratings do site dormitory panels achieve?
Rock wool sandwich panels achieve fire resistance of EI30 at 50mm thickness, EI60 at 80mm, and EI120+ at 100mm per EN 13501-2 testing, meaning the panel maintains structural integrity, insulation, and integrity for 30 to 120 minutes under direct fire exposure. The inorganic silicate fiber structure releases no toxic smoke, with smoke toxicity index below 0.5 per ISO 13344 standards for safe occupant evacuation.
3. What panel thickness do I need for my dormitory project?
Panel thickness ranges from 50mm to 150mm depending on climate zone and fire code requirements. Standard construction site dormitories in temperate climates use 50-75mm rock wool panels for EI30 to EI60 fire resistance. Dormitories in extreme cold regions or requiring EI120+ fire compartmentation use 100-150mm panels, delivering thermal conductivity of 0.040-0.045 W/(m·K) for reliable year-round occupant comfort.
4. How do site dormitory panels perform under wind and snow loads?
Panels are engineered to withstand wind loads of 0.6-1.5 kPa and support floor live loads of 2.0-2.5 kN/m² for multi-occupancy dormitory use. The galvanized steel structural frame at 2.5-3.0mm thickness provides the load-bearing backbone, while the rock wool sandwich envelope contributes fire compartmentation and acoustic insulation of Rw 30-35 dB that reduces noise transfer between dormitory rooms for improved occupant rest.
5. Do site dormitory panels meet GB 50720 compliance requirements?
Yes. RaxPanel rock wool site dormitory panels comply with GB 50720 mandatory requirements for A-grade non-combustible core materials in construction site dormitory and office buildings. Core oxygen index meets or exceeds 32%, vertical combustion rating achieves GB/T 8625 FV-0 class, and documentation includes verified test reports confirming A1 classification per GB 8624 for occupant building fire safety compliance.
