Brick slip EWI in Rhondda: questions
Do I need planning permission for external wall insulation in Rhondda?
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 Tonypandy as well as Rhondda?
Yes. From Rhondda we also cover Tonypandy, Aberdare and Pontypridd, and the rest of Mid Glamorgan.
Which EWI system suits homes in Rhondda?
It depends on the walls. Most brick houses in Rhondda 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.
