Glad you started this topic! I am considering brick slips on top of 200mm EWI for the front of the house. It would make it look very similar to the row of semis we are in, which is good as it would do away with the need for planning application (or so the council officer assured me).
The vandersanden solution looks very much like what alumasc offer. The downside is that you are tied to their grooved insulation boards. As I already have the EPS boards (thanks to a generous forum member :-) I am considering the Weatherby system where a ridged metal mesh is pinned on top of the EPS, with additional fixings into the wall. To me this looks like a more robust solution for carrying the weight of the brick slips, and the ridges ensure nicely aligned and spaced bricks.
After receiving a few samples I am even considering acrylic brick slips as these look good at much less weight.

Any suggestions as to what brick slip systems people have used on top of 200mm EPS, and are quicker to install than aligning the slips individually are veryveryvery welcome.

Have a look at Monolith, who have a few options for brick slip type products, with insulation and with panels for 12 in one piece, saving on some installation costs.

I have no connection and went for a relatively standard build in the end (fulfil cavity, with bricks on the outside)

We did one wall of an old extension, formed insulation with ridges, pistol slips for the external corners worked well and difficult to tell ir is not real brickwork

I have seen commercial systems on flats recently too

Yes, that does look good.

If only someone could provide a similar system looking like really-random-rubble stone! i.e. huge variation in stones and undetectable course/modules.

Yes, not bad. But 40mm thick, inevitably for such high-relief surfaces. 65kg/m2.

"Supporting Structure:
Standard block cavity wall. If on timber frame, the wall should first be clad with a cement-based board.
Z-Stone should not be fixed directly onto timber, plasterboard or painted surfaces"

So with EWI of significant thickness, over say 50mm, wd have to be treated like other claddings like boarding (other than direct render or direct-fixed brick slips). The whole cladding on backing board would have to be suspended from above, from overhanging rafter ends or similar.
That is, can't rely on fixing the backing board by cantilever action of lots of screws through anything more than thin EWI.

But all in all, subject to inspection of finished jobs - a great possibility of using stone with EWI, which up till now has seemed to necessitate founds and base walls for 150-200mm of stone plus perhaps a blockwork backing - at great cost.

Posted By: bhommelsThat does look good indeed, thanks for posting the picture. And since Weatherby assured me they have fixings compatible with 200mm thick EWI I think I just made a decision. Did you install it yourself BTW?
Are these the Weatherby supplied slips or from another supplier?

Yes, I fitted Bluclad board, which was one they recommended, and then used all their fittings and slips including adhesive and grout/mortar. It's like tiling but the mesh keeps the slips in place.
