Brick slips - insulation - block inner leaf
or
Brick slips - insulated concrete formwork (ICF)

It seems to me this would have the potential to include a lot more insulation than with traditional brick-cavity-insulation block.

The Belgian company Vandersanden says brick slips are 20% more expensive than regular bricks but the way they are fixed to special insulation looks a lot easier than laying bricks. Potentially making the outer skin a DIY job, or DIY with professional pointing?

I've no links with this company.]]> Brick slips - insulation - blocks https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270606#Comment_270606 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270606#Comment_270606 Wed, 10 Oct 2018 13:43:17 +0100 bhommels 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.]]> Brick slips - insulation - blocks https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270608#Comment_270608 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270608#Comment_270608 Wed, 10 Oct 2018 16:39:41 +0100 fostertom https://www.permarock.com/ewi-for-existing-buildings/decorative-renders-finishes-effects/permarock-brick-effect-render

I have no connection and went for a relatively standard build in the end (fulfil cavity, with bricks on the outside)]]> Brick slips - insulation - blocks https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270610#Comment_270610 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270610#Comment_270610 Thu, 11 Oct 2018 07:23:04 +0100 CWatters Posted By: bhommelsGlad you started this topic! I am considering brick slips on top of 200mm EWI for the front of the house.

Over in Belgium they have tax incentives which seems to encourage people to buy older houses and improve them. Using EWI and brick slips seems to be popular but not see it over here.]]> Brick slips - insulation - blocks https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270611#Comment_270611 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270611#Comment_270611 Thu, 11 Oct 2018 07:35:29 +0100 tony

If only someone could provide a similar system looking like really-random-rubble stone! i.e. huge variation in stones and undetectable course/modules.]]> Brick slips - insulation - blocks https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270618#Comment_270618 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270618#Comment_270618 Thu, 11 Oct 2018 11:58:22 +0100 CWatters Posted By: fostertom

"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.]]> Brick slips - insulation - blocks https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270620#Comment_270620 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270620#Comment_270620 Thu, 11 Oct 2018 12:46:56 +0100 bhommels Posted By: PeterStarckWe used the Wetherby system for a brick plinth wall. Very easy to use and everyone so far has thought it was brick.
That 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?]]> Brick slips - insulation - blocks https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270621#Comment_270621 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270621#Comment_270621 Thu, 11 Oct 2018 13:09:08 +0100 PeterStarck Posted By: bhommelsThat does look good indeed, thanks for posting the picture.

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.]]> Brick slips - insulation - blocks https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270626#Comment_270626 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=15890&Focus=270626#Comment_270626 Thu, 11 Oct 2018 22:08:16 +0100 Pile-o-Stone Posted By: CWatters

These look great. I have a garden wall with their name written on it. Any idea of the cost per m2?]]>
