Choose the Right Insulated Sandwich Panel for Your Project
The right insulated sandwich panel is the one that matches the building’s use, design requirements and installation conditions. Start with the application, then compare the available panel configurations against the project specification.
Wall Panels or Roof Panels?
Wall and roof sandwich panels should not be selected on thickness alone. Review the proposed product’s intended use, profile, joint geometry and fixing details.
For wall applications, consider the façade layout, panel orientation, openings and finish. For roof applications, coordinate the panel system with the roof design, drainage details, penetrations and supporting structure.
Compare the Requirements That Matter
| Selection Factor | What to Confirm |
| Building Application | External wall, roof or another specifically approved use |
| Thermal Requirements | Project insulation target and the declared performance of the proposed panel |
| Fire Requirements | Applicable project criteria and documentation for the relevant assembly |
| Exposure Conditions | Moisture, corrosive conditions, cleaning requirements and external exposure |
| Architectural Finish | Colour, surface profile, joint appearance and installation direction |
| Structural Coordination | Support spacing, design loads and product-specific engineering information |
| Installation | Fixings, seals, trims, openings and connection to adjacent construction |
| Procurement Scope | Panel quantities, accessories, packing, delivery requirements and supply responsibilities |
Define Performance Before Finalising Thickness
Insulated sandwich panel thickness is only one part of the specification. Core material, metal facings, joints and installation details also need to be defined.
If your tender includes thermal or fire-performance criteria, send the relevant requirements with your enquiry so the proposed panel can be reviewed against them.
Panel Joints, Fixings and Accessories
The insulated sandwich panel package needs more than the panels themselves. Joints, fixings, flashings and seals must be coordinated with the building details and the selected panel system.
Define these items early to clarify the scope of supply and reduce missing information during quotation and installation planning.
Joint and Fixing Details
Carefully review how each panel connects to adjacent panels and how the complete panel system is secured to the supporting structure. Confirm the joint profile, connection method, fastener type, fixing spacing, support requirements, and allowable installation tolerances for the selected panel model. Sealing materials, gasket positions, sealant application, flashing details, and thermal-break requirements should also be verified to ensure reliable air tightness, water resistance, thermal performance, and long-term durability. All joint and fixing details must be coordinated with the project drawings, structural design, site conditions, and applicable performance requirements before installation begins.
Flashings and Interface Details
Proper flashing and interface design helps create a weather-tight, durable, and visually consistent building envelope. Panel transitions should be carefully coordinated at corners, eaves, ridges, parapets, door and window openings, wall-to-roof connections, and interfaces with adjacent construction.
Flashings and trims can be customized to match the panel profile, thickness, joint configuration, coating, and project dimensions. Correct detailing helps reduce the risk of water penetration, air leakage, exposed insulation, and thermal bridging while providing a clean finished appearance.
For accurate quotation and fabrication, please provide architectural drawings, panel layouts, connection details, opening dimensions, or relevant sketches. Matching ridge caps, corner trims, eave flashings, opening trims, base flashings, and other customized accessories can be supplied as part of the complete wall and roofing system.
Confirm the Accessory Scope
The complete insulated sandwich panel system requires more than the panels themselves. Depending on the wall or roofing system, panel profile, connection method, and project design, matching accessories may be required to ensure secure installation, reliable sealing, weather resistance, and a clean finished appearance.
Typical accessories include panel fixing components, screws and fasteners, joint seals, sealing materials, internal and external corner trims, door and window opening trims, ridge caps, eave flashings, base flashings, and other project-specific interface components.
Flashings and trims can be customized according to the panel profile, project dimensions, bend angles, material thickness, coating, and color requirements. For special connections, customized accessories can also be fabricated based on architectural or shop drawings.
To ensure accurate pricing and complete material preparation, please provide panel layouts, opening dimensions, connection details, and relevant drawings when requesting a quotation. Accessory types, quantities, specifications, and supply responsibilities should be clearly confirmed before production and shipment.

More About Our Company
Manufacturing and Quality Control
An insulated sandwich panel manufacturer should be evaluated on more than a product image or headline specification. Consistent materials, controlled production and traceable product information are important parts of project procurement.
Glostar’s building materials offering is supported by a group manufacturing background. For your project, confirm the manufacturing entity, agreed product specification and applicable quality documentation as part of the technical and commercial review.
Material Specification
Define the core material, metal facings, coating and other agreed components before production.
The purchase specification should identify the product being supplied rather than rely on a general product-family description.
Production and Inspection Requirements
Agree on the inspection scope for the order, including relevant dimensional, visual and other product-specific checks.
Where inspection records or additional verification are required, identify these requirements during quotation.
Technical Documentation
Request documents that correspond to the proposed product and its intended use. Depending on availability and project requirements, these may include product data sheets, connection drawings, test reports and relevant quality documents.
Packing and Delivery Coordination
Confirm panel lengths, packing requirements, unloading conditions and delivery arrangements before order release.
Clarify how panels and accessories will be identified so the supplied materials can be matched to the project schedule.
Insulated Sandwich Panel FAQs
An insulated sandwich panel is a composite building panel with an insulating core between two facings. In metal-faced systems, the facings and core form a factory-produced panel that can be specified for particular wall or roof applications.
The intended use and performance depend on the complete product configuration.
Start with the application and project requirements. Confirm whether the panels are for walls or roofs, then review insulation targets, fire-performance criteria, exposure conditions, finishes and installation details.
The next step is to compare suitable product models using their specific technical documentation.
Choose thickness against the required performance of the building and the technical data for the proposed panel.
Do not assume that two panels with the same thickness provide the same performance. Core material, facings, joints and the installation arrangement also need to be considered.
Do not assume that wall and roof panels are interchangeable. Their profiles, joints, fixing arrangements and intended uses may differ.
Check the proposed model’s technical information and coordinate it with the project design before confirming the order.
Discuss the required panel lengths, thickness, metal facings, colour and coating during enquiry. Available options and manufacturing limits depend on the selected product.
Available lengths, dimensions, colours and finishes depend on the product series and order requirements.
Include your preferred specification in the enquiry so availability, production constraints and transport considerations can be checked before quotation.
