Brick slip EWI in Newtown: questions
How much should I budget for brick slip external wall insulation in Newtown?
Budget around £185–£265 per square metre of wall for the system and finish, plus scaffolding priced per house. The survey measures your walls in Newtown and fixes the total in writing.
Do I need planning permission for external wall insulation in Newtown?
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.
Which EWI system suits homes in Newtown?
It depends on the walls. Most brick houses in Newtown 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.
