    Hi my 1930 semi is a solid wall construction and externally pebble dash rendered.

    I am looking into EWI options and I wonder if anyone tried to use the SuperQuilt system?

    Their datasheet claims two 38mm cavities + the superquilt sandwiches between can achieve 0.30 U-Value.

    Very impressive to me and in particular:
    1. Vapour control layer is quite robust
    2. Potentially I do not need to hack of the existing pebble dash?

    Any opinion?

    Alternatively, I looked into EPS board also... Do I need to remove the existing rendering in that case?

    Thank you and Regards

    Super quilt and the like are not that credible for internal insulation, so I'd hate to think how it performs externally. Heat coming out the house wall into a ventilated cavity does not seem to be a good way of insulating.

    As for the render, that's for the installation firm to decide and worry about. You'll need to check their product certification and install guide.
