What is brick slip external wall insulation?

Brick slip EWI in Farnborough: questions
Is building control approval needed for brick slip external wall insulation in Farnborough?
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.
How long will the work take in Farnborough?
Two to six weeks on site for most houses, depending on size: bungalows are quicker, detached houses longer, weather allowing. Render isn't applied in rain or frost.
Which EWI system suits homes in Farnborough?
It depends on the walls. Most brick houses in Farnborough 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.
