Sandwich Roof/Wall Panel For Construction Materials

A sandwich panel is a product used to clad the walls and roofs of buildings. Each panel comprises a core of thermoinsulating material, skinned on both sides with sheet metal. Sandwich panels are not structural materials but curtain materials. The structural forces are carried by the steel framework or other carrier frame to which the sandwich panels are attached.

The types of sandwich panel are generally grouped by the thermoinsulating material used as the core. Sandwich panels with cores of EPS (expanded polystyrene), mineral wool and polyurethane (PIR, or polyisocyanurate) are all readily available.

The materials mainly vary in their thermal insulating performance, sound insulating performance, reaction to fire and weight.

• Any type of sandwich panel will do as cladding for walls and roofs.

Given the short installation time and large unit coverage, sandwich panels are most popular in constructing:

• Warehouse buildings
• Logistic hubs
• Sports facilities
• Cold stores and freezers
• Shopping malls
• Manufacturing buildings
• Office buildings

Sandwich panels can be combined with other structural solutions. A popular option is to install the panels as external cladding for the outer walls of shopping malls, including sandwich-layered roofing structures: box profile sheets, thermal insulation, and a waterproof membrane.
