Roof Sandwich Panel Specifications & Selection
The performance of an insulated roof depends on how panels, joints, fixings and finishing details work together. Glostar’s roofing options address different priorities within that complete assembly.
Profiled Surfaces & Joint Detailing
Roof profiles guide rainwater towards the drainage system, while correctly specified overlaps, seals and flashings help protect connections. Side laps, end laps, ridges, eaves and penetrations should be detailed for the selected roof configuration.
Thermal Insulation Across the Roof
An integrated insulation core helps limit heat transfer through the roof. Core selection and thickness should be coordinated with joint continuity, air sealing and condensation control to support the building’s thermal design.
Acoustic Options for Large Enclosed Spaces
Selected rock wool roof sandwich panels use a perforated internal liner to provide sound absorption. This is particularly relevant where the underside of the roof forms part of the room’s acoustic environment.
Factory-Assembled Roofing Components
Metal facings and insulation are assembled before delivery, reducing the number of separate layers handled on site. Coordinating roof sandwich panel lengths and installation sequences with the roof layout helps simplify site planning.
How to Specify Roof Sandwich Panels for Your Project
Start with the roof geometry, support structure and required building performance. Roof sandwich panel thickness alone does not determine whether a roof sandwich panel is suitable: profile, metal thickness, fasteners, support spacing and connection details also affect the proposed system.
| Specification Item | Options and Selection Considerations |
| Insulation core | PU/PIR, rock wool and selected glass wool configurations, depending on the product |
| Panel thickness | Selected rock wool roof sandwich panel models offer thicknesses from 50 to 200 mm; available sizes vary by product |
| Effective cover width | 1,000 mm is available on several models; confirm the selected profile before preparing the panel schedule |
| Metal facings | External profiled steel with an internal steel liner; perforated internal facings are available on acoustic models |
| Surface coating | PE, SMP, HDP and PVDF options, subject to the selected facing specification and exposure conditions |
| Roof slope and drainage | Coordinate roof pitch, drainage length, side laps, end laps, gutters and outlets |
| Structural requirements | Review purlin spacing, downward loads, wind uplift, fixing details and permitted deflection |
| Fire and thermal performance | Specify the required classifications and thermal target, supported by documentation for the proposed configuration |
| Roof openings and equipment | Coordinate rooflights, ventilation openings, service penetrations, access routes and any PV mounting system |
| Panel length and delivery | Coordinate cut lengths with roof geometry, transport limits, lifting equipment and site access |
Available specifications are product-specific. Request the relevant datasheet and connection details before finalising the roof sandwich panel schedule.

Roof sandwich panel prices vary according to the insulation core, panel thickness, steel facing thickness, roof profile, coating, panel length, order quantity and project requirements. PU/PIR and rock wool roof panels have different thermal, fire and structural characteristics, so the final cost should be evaluated according to the required roofing configuration rather than panel area alone.
For an accurate quotation, send us your required panel type, thickness, roof area or quantity, project location and delivery requirements. If roof drawings or a panel schedule are available, Glostar can review the project information and recommend a suitable panel configuration before preparing the quotation.
Roof Sandwich Panel Applications
Industrial Factories & Workshops
Insulated roofing for production buildings where thermal conditions, roof openings and equipment interfaces need to be coordinated. Sandwich panel selection should reflect the manufacturing environment, including internal humidity and potential corrosive exposure.
Warehouses & Logistics Centres
Roof sandwich panel systems for storage and distribution buildings with repetitive structural bays and large roof areas. Key considerations include panel layout, purlin spacing, drainage routes, rooflights and delivery sequencing.
Food Processing & Temperature-Controlled Facilities
Roofing for buildings with defined internal temperature and humidity requirements. Review insulation continuity, vapour control, joint sealing and the suitability of the internal facing as part of the roof design.
Sports Halls & Acoustic-Sensitive Buildings
Selected acoustic rock wool roof sandwich panels for spaces where sound absorption at roof level is required. Coordinate the perforated liner and panel configuration with the room’s acoustic design and environmental conditions.
Commercial & Public Buildings
Insulated roofing for buildings that require coordinated thermal performance, internal appearance and weather protection. Roof access, service penetrations, ventilation equipment and maintenance requirements should be addressed during specification.
Manufacturing Strength for Your Roofing Project
The roof sandwich panel supplier needs to coordinate more than panel production. Roof geometry, panel lengths, insulation requirements and connection details must come together in a package that can be manufactured, transported and installed as planned.
Glostar combines manufacturing scale with building envelope expertise to support contractors, distributors and project owners sourcing insulated roof sandwich panels. From product selection to production coordination, we help translate project requirements into a defined roofing supply package.

Roof Sandwich Panel FAQs
PU and PIR roof sandwich panels use rigid foam insulation cores, while rock wool roof sandwich panels use a mineral fibre core. Compare the proposed products against the required thermal performance, fire classification, weight and roof design. Where internal sound absorption is needed, consider a dedicated acoustic configuration rather than selecting by core material alone.
Start with the required thermal performance and then check the proposed panel against the roof’s structural conditions. Core type, metal facing thickness, profile, purlin spacing and design loads all matter. The roof sandwich panel’s thickness should be selected using the relevant product data rather than climate or span alone.
Depending on the product, roof sandwich panels may use profiled overlaps, anti-capillary features and specified sealing details. Weather resistance also depends on correctly installed fasteners, end laps, flashings, ridges and penetrations. Panels and accessories should be detailed as one coordinated roof assembly.
Do not assume that an installed panel roof is suitable for unrestricted access. Construction and maintenance access must follow the approved roof design and the manufacturer’s instructions. Load limits, support positions, walkways and fall protection need to be addressed before access is permitted.
Selected roof sandwich panels can be assessed for PV applications. The review must cover the mounting method, additional loads, wind uplift, waterproofing interfaces and the load path into the supporting structure. Compatibility should be confirmed for the specific roof and mounting system.
Packaging and loading are arranged according to the roof sandwich panel profile, length, quantity and transport method. Discuss shipping limits, surface protection, unloading equipment and site storage before placing the order. Production lead time and the delivery programme are confirmed with the quotation and order schedule.
