Brick slip EWI in Portslade: questions
Is building control approval needed for brick slip external wall insulation in Portslade?
Insulating more than half of a wall, or more than a quarter of the whole building envelope, counts as renovating a thermal element under the Building Regulations, so the wall should reach 0.30 W/m²K where that is technically, functionally and economically feasible, and building control must be involved. We arrange it as part of the job.
Do you cover Hove as well as Portslade?
Yes. From Portslade we also cover Hove, Brighton and Worthing, and the rest of East Sussex.
Which EWI system suits homes in Portslade?
It depends on the walls. Most brick houses in Portslade 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.
