Sandwich panel systems consist of an insulating core bonded between two metal facings. Thanks to their lightweight construction and excellent thermal insulation performance, they are widely used in industrial buildings. They are commonly specified as roofing and façade systems for factories, warehouses, logistics centers, manufacturing facilities, agricultural buildings, and cold storage facilities.
In these systems, panels must not only be securely fixed to the supporting structure but also sealed at their joints to ensure airtightness, watertightness, and vapor tightness. Proper sealing of panel joints is particularly critical in cold storage facilities and climate-controlled buildings, where it directly affects energy efficiency and overall system performance.
Adhesives and sealants are commonly used in the following sandwich panel applications:
Panel joints
Roof panel connections
Façade panel joints
Ridge and eaves details
Corner profiles
Perimeters of doors and windows
Chimney and service penetrations
Roof skylights
Fastener and fixing point sealing
Maintenance and repair applications.
Products used in these applications are expected to provide excellent adhesion to metal substrates, outstanding resistance to outdoor environmental conditions, and sufficient elasticity to accommodate panel movement.
Technologies Used
Neutral Silicones
Neutral-cure silicones provide reliable sealing solutions for panel joints thanks to their excellent weather resistance and long-lasting elasticity.
Typical applications include panel joints, roof details, façade joints, and perimeter sealing around metal frames.
Polyurethane Sealants
Polyurethane sealants are suitable for panel connections requiring high mechanical strength and for joints subjected to vibration.
Their elastic properties allow them to accommodate panel movement while maintaining long-term joint integrity.
Polyurethane Assembly Foams
Although used to a more limited extent in sandwich panel systems, polyurethane installation foams are suitable for insulation applications such as filling panel cavities, sealing around door frames, window perimeters, and service penetrations.
Hybrid Polymer Technology
Hybrid Polymer-based products are versatile adhesives and sealants widely used in sandwich panel systems.
They offer excellent adhesion to galvanized steel and pre-painted metal surfaces, combined with permanent elasticity, outstanding UV resistance, excellent weather durability, and, depending on the product, paintability.
They are particularly preferred for sealing panel joints and installing auxiliary metal profiles.
