Structural Integrity
High-Rib Trapezoidal Geometry & Capillary Lock
The external face incorporates stiffening trapezoidal ribs (35 mm - 40 mm rib height) that act as load-bearing structural beams, allowing wider purlin spacing and lowering overall structural steel usage. The side lap features a deep overlap with an anti-capillary groove and factory-placed butyl sealant to prevent water creep under tropical downpours and sand penetration in desert environments.
Effective Cover Width
1,000 mm
Standard Lengths
Up to 15.0 m (Transportable)
Steel Facers Grade
DX51D / S250GD (Z275 / AZ150)
Top Coating Options
Polyester (25µ), SMP, PVDF (28µ)
Installation Performance
Total Water Barrier Without Secondary Membranes
Unlike built-up roofing assemblies that require separate deck sheets, vapor retarders, spacer bars, rock mineral insulation, and outer standing seams, Emaar PUR/PIR sandwich panels are installed as an all-in-one unified composite element.
Contractors benefit from a 60% faster installation pace, reduced site labor, lower crane deployment times, and eliminated exposure of insulation to rain or humidity during construction phase.
Why Engineers Specify Emaar
Built for Harsh Climatic & Industrial Environments
Our sandwich roofing systems combine German-engineered automated high-pressure continuous foaming with certified steel feeds to guarantee dependable long-term field performance.
Significant Energy Reductions
Closed-cell core density of 40–42 kg/m³ with over 95% closed-cell content provides an airtight envelope that suppresses thermal conductivity to 0.020 W/m·K, slashing HVAC operating cooling costs by up to 40% across Gulf summers.
Certified PIR Fire Protection
Our PIR formulation contains advanced polyisocyanurate ring compounds that char upon direct flame exposure without producing melting drops. Panels achieve European Class B-s1, d0 classification in conformity with EN 13501-1 and Civil Defence standards.
Corrosion & UV Shield
External steel facers receive premium zinc coating (275 g/m²) or Aluzinc (AZ150) paired with multi-layer high-durability polyester or PVDF coatings, engineered to withstand aggressive coastal marine salts and high UV solar radiation.
High Span & High Load Capacity
The rigid foam core remains continuously bonded to profiled steel facers via auto-dispensed polyurethane adhesive. This composite structure demonstrates high shear resistance, allowing substantial purlin spans and handling heavy solar panel arrays.
Precision Factory Manufacturing
Produced on fully automated continuous production lines in Muscat with high-precision cutting, edge profiling, and uniform density distribution, eliminating hot-spots, delamination, and on-site dimension discrepancies.
Short GCC Logistics Lead Time
Strategically located in Oman with streamlined customs clearances and daily direct transport to the UAE, Saudi Arabia, Qatar, Bahrain, Kuwait, and East Africa, eliminating transoceanic shipping delays and container handling damages.
Technical Knowledge Base
PUR & PIR Roof Panels Frequently Asked Questions
Comprehensive technical guidance compiled by our structural and thermal insulation engineers to support project tenders, consultant submittals, and MEP coordination.
Emaar Industries manufactures continuous PUR and PIR roof panels in standard nominal core thicknesses of 30 mm, 50 mm, 75 mm, 100 mm, and 150 mm. Custom project thicknesses can also be manufactured depending on specific structural engineering span limits and consultant U-value specifications.
Thickness is determined by internal building operation temperatures, thermal envelope energy compliance codes, and purlin spacing. For non-conditioned warehouses or industrial storage, 30mm to 50mm panels provide condensation control and moderate insulation. For climate-controlled production facilities, pharmaceutical buildings, and commercial retail centres, 75mm to 100mm is recommended. For cold chain facilities and blast chiller roofs, 150mm provides the required deep thermal resistance.
The primary difference is thermal performance and load-bearing span capacity. A 50 mm PIR panel delivers a U-value of approximately 0.43 W/m²·K, suitable for general ambient industrial use. A 100 mm PIR panel cuts heat transmittance in half to roughly 0.21 W/m²·K, drastically reducing indoor air-conditioning loads and permitting wider purlin spans due to increased composite cross-sectional flexural stiffness.
Yes. Our roof panels are engineered specifically for Middle Eastern environmental extremes, where roof surfaces can reach 80°C to 85°C under direct solar radiation. The high dimensional stability of our PIR formulation prevents thermal blistering and warpage, while certified anti-corrosion protective coatings (such as Super Durable Polyester or PVDF) defend against coastal salt-spray and abrasive dust storms.
Yes. The high-rib trapezoidal profile provides substantial mechanical load strength. Photovoltaic solar mounting brackets can be mechanically fastened directly into the major structural ribs using specialized self-drilling non-penetrating clamps or EPDM-gasketed self-tapping structural fasteners without compromising the underlying thermal foam core or building water-tightness.
No. Emaar PIR/PUR roof panels function as an integrated, self-sufficient weatherproof roofing envelope. The profiled outer steel skin manages water discharge, the rigid core provides an unbroken vapor barrier, and the interlocked longitudinal joints with integrated anti-capillary breaks eliminate water ingress without requiring built-up felt, bituminous membranes, or supplementary insulation layers.
