Metal Composite Material (MCM) Panel Systems

Sobotec predominantly uses Alucobond®for its MCM Panel Systems.  Alucobond®is a global brand leader for metal composite material (MCM) and has been time-and-laboratory tested to meet stringent building code requirements. Developed in 1969, Alucobond®manufactured the original aluminium composite material (ACM), which is also known as MCM. Sobotec is credited for being the first company to develop an engineered Rainscreen System for aluminum composites. This innovation revolutionized the use of the material for the architectural and building industries in North America. Sobotec is one of only a handful of companies to be certified by the Metal Construction Association (MCA) as a Certified Premium MCM Fabricator.


Rout & Return Caulked System

The SL-1000 system is technically equal to the SL-2000 system, with the exception of the panel joint treatment. The system has also been structurally tested to the same stringent criteria. This system is mostly used in Rainscreen applications where virtually all water infiltration is eliminated in the vented cavity. An air barrier is required behind panels under these conditions. In other applications, the SL-1000 can be used as a fully sealed system which relies on the face sealant to act as the primary weather barrier.  This system is a traditional system in applications where the seal cannot be guaranteed by membranes and is still used on simple to complex applications.

Special Features

  • Pressure-Equalized Rainscreen System
  • Can be designed as a fully face sealed system

Dry Joint Pressure Equalized Rainscreen (PER) System

This legendary system revolutionized the architectural panel system industry.  Introduced to the market by Sobotec in 1993, it has become the most widely used and specified system for MCM.

For years, architects had been requesting a low-maintenance and flexible pressure-equalized rainscreen panel system.  We listened and were the first in the industry to pioneer and develop this system for metal composite materials.  The SL-2000 is tested to the American Architectural Manufacturers Association (AAMA) 508 standard for Pressure Equalized Rainscreen (PER) Systems. The MCM joint filler allows variance in both colour and joint size.  The SL-2000 system offers a crisp, clean, high-tech look to today’s architectural community.  This system has been continuously upgraded and tested using Metal Composite Material and solid aluminum plate as per the changing North American building code requirements. The test report is available to design professionals through Sobotec’s engineering department.  Contact us today to discuss how this proven system can assist you on your next project.

Dry Joint Gasketed System

Sobotec's SL-3000 is a high performance, dry-joint system utilizing an extruded horizontal and vertical guttering system. The joint seal is accomplished by the use of neoprene gaskets placed within the perimeter extrusions. Perimeter extrusions reinforce and encapsulate panel returns, eliminating any exposed cut edges. The standard reveal colour is black with optional colours available. To accommodate various accent expressions, vertical and horizontal extrusions are available in various sizes or can be extruded to suit various custom designs.

Special Features

  • Secondary gutter ensures water tight performance
  • Encapsulated panel edge
  • Air barrier membrane provides improved weather resistance
  • Low maintenance

System Characteristics

Material: Metal Composite Material
Joint Type: Extruded, Painted and Gasketed Aluminum
Standard Joint Size: 3/4"
Testing: Tested to AAMA 501 Standard. AAMA 501.1, 501.4, ASTM E283, E331, E330
Wall Design: Rainscreen and Pressure Equalized or Sealed


Dry Joint Snap-In Reveal System

The SL-4000 is a very unique Pressure-Equalized Rainscreen System which allows individual panels to be easily removed and replaced. Originally designed specifically for the Windsor Casino (now known as Caesar’s Casino Windsor) this was one of the largest applications of Alucobond® material in North America. Throughout its 375,000 sq. ft. panel area, the aluminum extruded two-part, snap-in reveal allows for expansion and contraction at each individual panel. Its exclusive characteristics and widespread recognition made the SL-4000 another one of Sobotec's popular, engineered-performance designs.

Special Features

  • Panels are able to be easily removed and replaced
  • Custom-designed, high-performance system
  • Utilizes a unique two-part snap-in extruded reveal

System Characteristics

Material: Metal Composite Material
Joint Type: Non-progressive, individually removable panels
Standard Joint Size: 3/4"
Testing: Full scale wall test at Construction Research Laboratory Inc., Miami, Florida
Wall Design: Rainscreen & Pressure Equalized
