Modern modular construction relies on the structural composite action of sandwich panels. By bonding dual high-tensile metallic facings to a lightweight thermal core, sandwich panels deliver unprecedented strength-to-weight ratios, structural rigidity, and thermal resistance.
| Core Insulation Material | Thermal Conductivity (λ) | Fire Behavior Class | Compressive Strength | Optimal B2B Application |
|---|---|---|---|---|
| PIR (Polyisocyanurate) | 0.022 W/m·K | B-s1, d0 (Self-Extinguishing) | 150 - 200 kPa | High-efficiency cold storage, cleanrooms, energy-efficient housing |
| Mineral Rockwool | 0.038 - 0.044 W/m·K | A1 Non-Combustible | 80 - 120 kPa | Oil & gas camps, high fire-risk sites, acoustic partitions |
| PUR (Polyurethane) | 0.024 W/m·K | B2 / B3 Grade | 120 - 160 kPa | Standard commercial portacabins, site offices, mobile shelters |
| EPS (Expanded Polystyrene) | 0.035 - 0.039 W/m·K | B2 Standard Grade | 70 - 100 kPa | Budget temporary worker housing, lightweight hoarding panels |
Our male-female tongue and groove joint profiles feature concealed continuous gasket strips and thermal break gaps, preventing heat conduction and moisture condensation in sub-zero environments.
Encased in hot-dip galvanized steel skins (0.4mm to 0.8mm) treated with zinc coatings (Z120 to Z275) and outdoor-grade fluorocarbon (PVDF) paints for superior UV and saline corrosion resistance.
Modular cold room and housing panels are embedded with high-strength corrosion-resistant cam-lock fasteners, enabling rapid assembly and disassembly without specialized field welding.
As global construction shifts toward decarbonization, off-site prefabrication, and strict energy ratings, institutional buyers must align procurement strategies with emerging structural trends.
Global EPC contractors are mandating environmental product declarations (EPDs) for sandwich panel materials. Zero-ODP (Ozone Depletion Potential) and ultra-low GWP (Global Warming Potential) blowing agents such as Pentane are replacing legacy HCFC systems.
Procurement teams are shifting from traditional stick-built housing to BIM-integrated flat-pack systems. DfMA optimizes shipping container volume utilization, reducing international ocean freight costs by up to 60% per unit.
Future modular units integrate thin-film BIPV (Building-Integrated Photovoltaics) directly into the outer skin of sandwich panels, creating self-sustaining field offices and mobile cold chains for extreme environments.
Established in 2003 in Ras Al Khaimah, United Arab Emirates, RAM PREFABS LLC has grown into a premier multi-national manufacturer of prefabricated modular buildings, portacabins, modified shipping containers, and industrial cold room systems.
Clear, expert answers to key technical questions raised by B2B buyers, structural engineers, and global procurement agents.
PIR (Polyisocyanurate) sandwich panels provide unmatched thermal performance with a thermal conductivity as low as 0.022 W/m·K, making them ideal for energy-efficient prefab homes and cold storage rooms where space saving and low U-values are critical. Rockwool panels, with a thermal conductivity of ~0.040 W/m·K, excel primarily in fire resistance (A1 non-combustible rating) and acoustic insulation. Rockwool is preferred for oil & gas camps and high-density industrial sites requiring strict fire wall integrity, whereas PIR offers superior moisture resistance and structural strength per unit weight.
Our custom-engineered sandwich panel prefab houses are designed to meet international structural building codes (IBC / Eurocodes). Standard units withstand basic wind speeds up to 160 km/h (Category 3 hurricane resistance) and seismic acceleration up to Zone 4 parameters. For harsh desert or coastal marine deployments, the cold-rolled steel framing system and panel connections are structurally reinforced with heavy-gauge corner fittings and high-tensile structural fasteners.
Prefabricated houses can be shipped as fully assembled portacabins or knock-down "flat pack" systems. Flat pack cabin designs allow up to 4 complete modular units (including roof, floor chassis, structural posts, and insulated wall panels) to be bundled and shipped inside a single 40ft High Cube ISO shipping container. This reduces ocean transport volume by approximately 75% compared to fully welded pre-built units.
Thermal bridging is prevented by incorporating precision tongue-and-groove joint geometry equipped with internal PVCu thermal break profiles, continuous EPDM sealing gaskets, and recessed cam-lock latches. During installation, the male and female panel edges compress to form an airtight seal, preventing conductive heat transfer across the metal skin facings.
With regular maintenance, high-quality prefabricated sandwich panel houses have a design service life of 25 to 30+ years. The longevity depends on the metallic skin coating selected. Standard polyester (PE) coatings suit inland commercial sites, while Fluorocarbon (PVDF) or High-Durable Polyester (HDP) coatings are specified for coastal environments exposed to high salt spray and UV radiation.
Yes. We design hybrid solar-powered mobile cold storage rooms and off-grid accommodation units integrated with roof-mounted photovoltaic arrays, inverter systems, and lithium-ion or thermal energy storage banks. These units maintain continuous thermal regulation without requiring permanent electrical grid connections, making them ideal for agricultural harvesting and remote exploration camps.
