Sandwich panels

Types of insulating core

Sandwich panel insulating cores use:

• PUR — polyurethane foam
• PIR — polyisocyanurate foam
• RW — stone wool

The core material affects the panel’s thermal, acoustic and fire properties, as well as its weight. When selecting a panel, check the declared performance of the complete product. The reaction-to-fire classification of the insulating core should not be equated with that of the finished panel.

Sandwich panel applications

Sandwich panels are used in industrial, commercial, agricultural, residential and modular buildings. Choose the appropriate type for the application:

• Roof sandwich panels for roof surfaces.
• Wall sandwich panels for façades, internal walls and partitions.
• Cold-room sandwich panels for cold rooms and temperature-controlled spaces.
• Acoustic sandwich panels for applications requiring sound absorption.

Dimensions, load-bearing capacity and installation

Module width, length and available thicknesses depend on the panel model. Consult the selected product’s technical documentation for exact dimensions and manufacturing options.

Core thickness, metal facings and profiling are selected according to energy requirements, the span between supports and design loads. Load-bearing capacity is checked for snow, wind, self-weight and other anticipated loads.

The supporting structure, fastening method and joint details must comply with the project documentation and the manufacturer’s instructions.

How do you choose the right panel?

Consider the building’s intended use, thermal and acoustic insulation requirements, fire protection and operating conditions.

To compare thermal insulation, check the U-value for the selected model and thickness: a lower value means less heat transfer through the panel.

For help with selection, contact our technical consulting team. Please provide the building’s intended use, project requirements, required dimensions and panel quantity.
