RDX – ACM Dry Joint Rainscreen SystemGENERAL INFORMATION

The information in this manual has been prepared to assist the designerand installer with the proper application of Armetco’s RDX4 ACM DryRainscreen System. Since each project is unique, the information isintended to be used as a guideline and in no way ensures properapplication of ACM Dry Rainscreen System panels.

ALUMINUM COMPOSITE MATERIAL

Aluminum Composite Material (ACM) is the material of choicewhen panel flatness and a high performance finish are a must.Made from two sheets of aluminum bonded to a thermoplastic core,ACM is strong yet lightweight and, with the right product knowledgeand equipment, can be fabricated into panel systems that willaccommodate most of your cladding needs.

Armetco Systems offers a complete line of ACM products, systemsand services. With multiple attachment systems and access to all ofthe major Aluminum Composite Material manufacturers, Armetcohas an ACM solution for all applications.

Armetco’s RDX4 rout and return system is a dry joint, drained backventilated rainscreen ACM wall cladding system utilizing a factoryapplied continuous extruded aluminum perimeter attachment system,an easy to install bridge plate and a channel and weep system formaximum water integrity. No exposed sealant is required.

RDX4 perimeter extrusions are applied to the ACM panel byinserting and mechanically fastening the return panel leg into thecontinuous perimeter extrusion. Structural sealant, corner platesand a hidden fastener insure positive attachment. A “sealantpocket” is designed into the male (RDX4-M) and female (RDX4-F)extrusions to allow for proper curing of factory applied structuralsilicone as recommended by the structural sealant manufacturer.

At panel intersections, where other systems may require exposedsealant or cover plates, our molded bridge plate easily installs overthe top extrusion of the lower panel and under the bottomextrusions of the upper panel, to properly channel and control anyminor leakage that may occur at panel intersections and endconditions.

Additional features include the dovetailed receiver on the femaleextrusion for easier installation of longer panels, and specialextrusions for sill, corner, and end conditions.

The horizontal RDX4-M extrusion eliminates the need for horizontalsubgirts or furring channels and can be fastened through sheathinginto metal studs (at 16” O.C. max). For panel heights less than 30”,the RDX4-M carries the load without support or attachment at thevertical in most cases. A waterproofing membrane such asTyvek construction wrap is required.

Every project is shipped complete with installation drawings,installation instructions, detailed material lists, approved fabricationtickets, and clearly marked crates and panels.

Also available in 6mm (RDX6)

PROPER STORAGE

If panels are not to be used immediately, they should be stored inan area that is out of the way and suitable for storage until readyfor installation. Continual moving of crates and / or panels willcause damage to panels. Panels intended for exterior use can be

stored outside. Store crates on a solid surface. Keep the material offthe ground and Do NOT store crates on surfaces that are subject tomud or in drainage areas where water can reach panels. If cratesare wrapped in plastic, cut several large slits on the sides to allowventilation and reduce condensation. It is the responsibility of thecontractor / panel erector to insure that panels are properly storedat the jobsite.

PROPER UNLOADING & HANDLING

1. Inspect crates immediately for damage. Notify driver of anyvisible damage and record damage on driver’s copy ofshipping bill.

2. Inspect contents of crates within 24 hours of delivery3. Panel crates must be lifted from the bottom skid.4. For hoisting, use proper lifting straps that have been inspected

and are in good condition. DO NOT USE CABLE OR ROPE.5. Place panels in area that they can be stored safely until ready

for installation. Do not move crates and / or panels any morethan absolutely necessary. This will cause damage to panels.

6. Handle panels with multiple faces by lifting and / or supportingpanel’s at all or at least two faces. Failure to do this can causedamage to corner clips and supports and may cause the facesheet to split.

INSTALLATION

1. Install panels per Armetco installation instructions andapproved shop drawings. Refer to page 18 for installationillustrations.

2. If field verification of dimensions is required, record actual fielddimensions on 1 set of shop drawings and return to Armetcoengineering.

3. Review and approve Armetco fabrication drawings as required.4. Check support framing to be sure area to receive panels is

installed straight, plumb and in plane.5. Inspect waterproofing membrane for proper installation and

for rips or tears. If waterproofing membrane is not installedproperly and in good condition, make necessary repairs ornotify contractor immediately. DO NOT PROCEED withpanel installation until waterproofing membrane is inacceptable condition.

6. Install panels true, plumb, level and spaced properly (Seeillustration on page 18).

1. Starter strip must be installed first.Starter must be leveled, and withmitered cuts at corners.

2. The first panel (A) is set on thestarter using 1/2” shims toinsure a consistent joint. 3. The second panel (B) is installed in the

desired direction on the male leg using1/2” shims at the starter strip and betweenthe panels to insure a consistent joint.

4. A bead of sealant is then run on thebottom of the backer plate. The backerplate is then set in the pocket behind themale leg centering it over the splicebetween the panels.

5. Next, install the splice plate slippingit over the male leg at the splicebetween the panels. This will concealthe gap needed for thermalmovement while keeping a uniformcolor at the extrusion. Now installthe weep baffles at all weep holes.

6. Working vertically, the next panel (C)is installed similar to the first panel(A) using 1/2” shims to insure aconsistent 1/2” joint between thepanels. This panel will set over thebacker plate so that the backer platelaps under the panel 2”.

7. The next panel (D) is installedsimilar to panel (B) with 1/2”shims keeping a consistent 1/2”joint and making sure to keeppanels in line both vertically andhorizontally.

8. Repeat steps 1 through 7 as required.
