How to fit a sign onto an exterior insulation wall?

[Andrew O Brien]

Long screws and bond it to the wall?

[Robert Lambie]

Are you saying the face of the wall/building is actually the insulation?
Normally you will have a face panel, then insulation. This can be 1mm thick steel or even composite etc etc.

[Andrew O Brien]

They normally just put a special render applied over the insulation. Normally the insulation is around 100mm then the render. It would support nothing.

Did you do a site survey before agreeing to undertake the work ?

Is there any other location the sign could go

OK, got you now… and understand what you meant by long screws and liquid bonding.
Thing is, the screws are put in blind and depends what they hit to make a good fixing. The liquid bonding would obviously hold once set, but if the sign has to be removed, i would expect that to pull the render from the insulation.

What about using a wall masonry wrap?
just apply the prints directly to the wall with zero fixings.

I did a site survey, and I recommended a different location as being the best place to put the sign up, but they didn’t take my recommendation and was certain they wanted it on the insulation. :bangshead:

I think then I would consider Robs comments and possibly suggest to the client you apply a printed vinyl direct to the substrate

[Stephen Morriss]

Bit late but you needed to specify that you will not fit to the insulated wall or if you do you take no responsibility for any subsequent damage or leaks, even then you’d be better doing some research on specific wall fixings.

Or look into Robs suggestion.
