Aluminum composite “Rainscreen” wall cladding system.

The design of pressure equalized “rainscreen” curtain wall assemblies using Aluminum Composite Metal Panels (ACMP) – a dominant trend – has changed considerably over the years. Wall assemblies built according to the “rainscreen principle” consist of a cladding, a vented air space, and a metal subframe attachment system, with the curtain wall or load-bearing wall underneath.

SpandrelTech creates stronger, longer lasting, aesthetically superior cladding systems that feature design-unit integrity utilizing improved methods of adhesion between the ACMP and the fastening system while meeting or exceeding the most demanding specifications. A better panel system is also easier to install.

Attachment of the cladding to the protected wall traditionally employs an all-screw-fastened metal framing system.

SpandrelTech – with Compaspan™ – improves the installation process with a trademarked “snap-in” fastening system that secures the panels to the subframe, yielding better quality installations at reduced cost.

The panels are rout and return, pan formed and lightweight, consisting of a nominal 0.5 mm (0.020”) thickness aluminum skin on each side of a Polyethylene (PE) or Fire Rated (FR) core of nominal 3 mm (0.118”) thickness. The resulting panel is a nominal 4 mm (0.156”) thickness protected by a protective polymer release liner (strippable film) that is removed after installation.

The new trademarked “snap-in” attachment system in concert with traditional screw fastening reduces installation time (and cost) substantially. The aluminum subframe attachment extrusions are designed to allow for expansion and contraction (thermal movement) within the “rainscreen” wall. Panel bottoms have oblong weep holes and the panels use open cell foam to facilitate evaporation and drainage of any moisture entering the system.

Typical maximum panel height is 1524 mm (60”) with up to 1575 mm (62”) available. Maximum panel length is 4978 mm (196”). Panel depth is overall 51 mm (2”). Most manufacturers make their ACM available in 3 mm, 4 mm, 6 mm (0.118”, 0.156”, 0.234”) thickness.
