Sandwich Panel - The Versatile Building Material of Choice

Sandwich Panel

Sandwich panel are Insulated structural building panels consisting of an inner rigid insulation core bonded between two thin outer facings or skins. The insulation core is typically made of expanded polystyrene (EPS) or polyurethane while the facings are made of steel, aluminum or other metal sheets.

Advantages of composite panels

composite panels provide numerous advantages over site-built construction methods:

Speed of Construction

composite panels are prefabricated offsite which allows entire building envelopes or sections to be rapidly installed with little onsite labor. Complex building geometries can be easily achieved through prefabrication. This significantly reduces construction schedules compared to traditional building methods.

Thermal Insulation

The core insulation in composite panels provides excellent thermal insulation properties, reducing heating and cooling needs. EPS cores have high R-values allowing buildings to be energy efficient. This lowers long term operating costs of buildings.

Sound Insulation

In addition to thermal insulation, composite panels constructions also act as sound barriers due to the rigid insulation core damping structure borne noise transfer through the Sandwich Panels. This makes them suitable for applications requiring acoustic insulation like industrial facilities.

Durability

Sandwich panel facings protect the insulation core from moisture ingress and damage. The composite panel structure withstands impacts and point loading better than single skin constructions. This results in durable, long lasting buildings resistant to weathering and normal wear and tear.

Low Maintenance

composite panels have smooth, impervious panel surfaces that are easy to clean and require little maintenance. The insulated panel construction remains weatherproof and aesthetically appealing for decades with minimal upkeep.

Design Flexibility

composite panels can be produced in virtually any size up to 60 feet by 360 inches with complex geometries, shapes and details. This allows them to be used for virtually any type of building from warehouses to offices to retail structures.

Applications of composite panels

Some common applications of prefabricated composite panels include:

Commercial and Industrial Buildings

Large footprint single and multi-storey commercial, warehouse and industrial buildings are increasingly being built using composite panels construction systems. Their speed and ease of erection makes them well suited for projects requiring fast completion like distribution centers.

Cold Storage Facilities

Sandwich panel structures combined with insulated metal door systems provide the stringent thermal and moisture requirements for cold storage warehouses and food processing facilities.

Manufacturing Facilities

Factories involved in manufacturing, assembly and process plants utilize composite panels walls and roofs for their structural strength, durability in harsh environments and ability to span large uninterrupted areas.

Modular Construction

Panelized building systems and modular construction relying on prefabricated components made of composite panels have revolutionized construction approaches achieving unprecedented quality, speed, and cost control for projects.

Military and Temporary Structures

Their strength to weight ratio, rapid deployability and durability make composite panels well suited for military, disaster relief and temporary structures that may need to be transported or relocated frequently.

Types of composite panels Constructions

While the basic composite panels concept remains the same, several types are available based on facings and cores:

Steel-faced Panels - Thin galvanized steel, stainless steel or aluminum sheets are common facings providing durable, weatherproof and impact-resistant surfaces.

Composite Panels - Fiber reinforced plastic (FRP), fiber cement or wood panel facings produce aesthetic and non-conductive panel options.

Concrete-faced Panels - Insulated formwork panels with an interior concrete facing eliminate the need for on-site pouring of foundation or above ground walls.

Structural Insulated Panels (SIP) - Sheathed OSB or plywood facings bonded to rigid foam form an integrated, load bearing wall system replacing wood framing.

Changing Face of Construction

Prefabricated building systems especially those made using high-performance Sandwich panel are revolutionizing construction practices worldwide. Compared to traditional on-site methods, they deliver major advantages of cost, schedule and quality certainties. As sustainability and industrialization become greater priorities, composite panels will continue growing in popularity and applications. Their versatile performance and building capabilities make them a construction material of choice for the future.
