Panel Description
Sandwich panels are typically single piece, modular factory
engineered units comprising two metal faces and a fully insulating core.
The metal facings are fully bonded to the core so that the
panel acts compositely when under load, in most cases, providing free
standing panels. Facings used for insulated panels are predominantly of
steel.
The insulating core is typically bonded to the facings using
a conventional adhesive bond. If other than EP, the core material is
usually a material that provides good thermal insulation properties.
The panels are typically manufactured on a continuous production line, as shown below.
Core Materials
The following generic core material types are often used in Sandwich Panel:
- Expanded Polystyrene (EPS)
- Polyurethane (PUR)
- Polyisocyanurate (PIR)
- Mineral Wool / Stone Wool
- Phenolic foams
- Phenolic/EPS Composites
