Brick slip EWI in Rhosllannerchrugog: questions

Do I need planning permission for external wall insulation in Rhosllannerchrugog?

Welsh guidance allows cladding a house without an application if the materials look similar to the original, but external wall insulation that projects more than 16cm from the wall needs planning permission. Any cladding or render in a conservation area, National Park, AONB or World Heritage Site needs permission, listed buildings need consent, and permitted development rights may have been removed by condition or Article 4 direction.

Do you cover Wrexham as well as Rhosllannerchrugog?

Yes. From Rhosllannerchrugog we also cover Wrexham, Buckley and Hawarden, and the rest of Clwyd.

Which EWI system suits homes in Rhosllannerchrugog?

It depends on the walls. Most brick houses in Rhosllannerchrugog suit EPS with silicone render; older stone or lime-built walls suit wood fibre or insulating lime render; and blocks need mineral wool. The free survey recommends one and explains why.
