How to Select a Sandwich Panel Core for a Building Project

Sandwich panels should be selected as complete envelope systems rather than by core name alone. The intended building use, temperature range, fire strategy, acoustic need, span, finish, joint detail and maintenance environment all influence the specification.

Start with the application

Residential rooms, warehouses, cold rooms, clean spaces and temporary cabins have different requirements. Confirm whether the panel is intended for an external wall, internal partition, roof or controlled-temperature enclosure.

Review the complete panel

Core type and thickness are important, but facing thickness, coating, profile, joint geometry, fasteners, sealants, flashings and support spacing also affect durability and performance.

Coordinate interfaces

Openings, corners, roof-to-wall junctions, floor connections and service penetrations can become weak points when they are not detailed before installation. Accessories should be included in both the drawing and quotation.

Request traceable information

Use current manufacturer documents for composition, dimensions, declared performance, handling and installation requirements. Project-specific engineering and regulatory decisions should be confirmed by qualified professionals.
