System Description


6-8 mm stone layer

1mm fiberglass mesh with Epoxy

17mm honeycomb layer

1mm epoxy saturated fibre mesh backing called Pre-preg


Stone and Panels

Thickness:  Stones are usually 6mm thick however 8mm is available on request.  (thinner is more flexible, uses less stone and weighs less)  Blocks of stone are cut into slabs (usually 1” but dependent on finished size required).  1” slabs will yield 2,   8mm panels

Selection: Any granite, limestone and some marbles and slate and sandstones are suitable for us on the system. State Vein direction.

Book match: when a vein in one piece mirrors the next piece.  This can be done for a premium.  Often returns are a continuation of a vein as they are usually cut from the same panel

Panel Sizes: Maximum panel size is 58x140” (1524 x 3556mm). Panel sizes are limited by the slab size.  It is also possible to score the face of panels to make a large panel appear to be smaller by creating a false joint.  The exterior system measures 60 mm (2 3/8”) thick. (Panel is 25mm or 1”, brackets are 35mm or  1 3/8”).

Weights: panels weigh 3.7 lbs/sf, brackets weigh approx. 1.0 lb/sf (depending on frequency)




Stones are mounted onto the AHSP system and then they are finished in the same manner as a slab of dimensional stone. Polished, honed and sandblasted finishes are the most common.

Porcelain sheets are available in a selection of colours and finishes.  Porcelain thicknesses  vary from 3mm to 5mm and panel sizes are 90x180cm, 100x300cm or 120x360cm.




Honeycomb is made of aluminum alloy is 6063 T6 mill finish.

Mounting brackets are anodized for exterior only and can be butt directly to stainless steel

Bracket spacing is 24-48”

There are three types of mounting brackets:


-interior S clip; continuous channel is installed on the wall and the mate is pre-installed onto the panel backing.


-exterior interlocking; continuous channel is mounted onto the building and the mate is pre-installed onto the panel backing.  This rail is also used as a starter rail for the Stacking/Progressive Clip System.  On panels taller than 48” the intermediate rail will be the interlocking bracket.   Non- sequential removal requires a minimum joint size of 14mm for one panel and 9mm if you can shift the panel above.  Tighter joints will not allow for sequential movement.  (Only the interlocking bracket will allow for individual panel removal)

-exterior Stacking/Progressive clip; the continuous bracket is pre-installed on the back of the panel and it has a protrusion which sets up the next bracket by screwing it back to the substrate.

Corners and returns highlights: 

Corners and returns are factory made to have a virtually invisible detail

Returns of 2-4” are standard.  Larger returns can be discussed on a case by case basis



Factory can work from:

AutoCAD Drawing File  .dwg

Drawing Exchange File  .dxt

Shop Drawings

Factory can mark panel layout on the provided electronic drawings

Installer is responsible to mark-up for site measurements

Factory will produce final shop drawings for architect approval

Factory will produce fabrication/cut tickets



Minimum joint size is 6mm,  9mm is more common and can accommodate caulking

Joints maybe be sealed or left open



LEEDcontribution is for Regional Credit, recycled content is minimal.  The panels might also qualify for sustainable (no wastage on site) and reusable points.
