CSS has developed and refined a proven innovative method of installing
and anchoring stone cladding. ISR stands for Individual
Support and Retention. Each piece of stone is individually
supported and mounted to an aluminum grid framework. There are no
rigid connections providing applications for projects in areas with
A unique drilling process and a specially designed anchor holds
a panel clip to the back of the stone panel. The stone with the
panel clip is hung onto an aluminum grid framework. The support
of the panel from the back eliminates anchors in the joints and
provides twice the holding power, allowing larger panel sizes in
thinner stone and less weight on the structure. Because there are
no anchors in the joints the ISR Plus system is perfect for rain
screen applications. Why waste money on caulking the joints and
the ongoing maintenance of re-caulking? Leave the joints open and
let the building cavity breath and avoid damaging condensation.
ISR Plus is a totally mechanical system. There are no adhesives,
no mortar, and no silicone. The system allows the setting of stone
in freezing conditions unlike traditional mortar setting methods.
The schedule for installation of stone becomes much more flexible
as each course of stone is not dependent on the lower course. Once
installed the stone panels can be removed, if necessary, without
damaging the panel.
The installation of stone using ISR Plus is faster and more flexible
than traditional setting methods. Please contact us with questions
