Local considerations in Merthyr Tydfil
As well as Merthyr Tydfil itself, we quote in Aberdare, Rhondda and Ebbw Vale. Merthyr Tydfil sits around 7 miles from Rhondda. South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Parts of Mid Glamorgan fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.
We bring finish samples to Merthyr Tydfil surveys so colours can be judged in daylight against your roof and windows.

Permissions in Wales
We check Merthyr Tydfil addresses for conservation areas and listing before quoting, because Welsh permitted development rules don't cover every external change.
Building control in Wales applies to most insulation and re-rendering jobs of this size; the quote states who submits the notice.
Is insulated render the same as EWI?
Yes — insulated render is the everyday name for a rendered EWI system. Some people also use it for thin thermal renders containing aerogel or cork, which are applied 20–40mm thick on heritage walls. They insulate far less than board systems, so we treat them as a specialist option.

Insulated render in Merthyr Tydfil: questions
How long does insulated render last?
Typically 25–30 years or more with maintenance; the manufacturer's documentation sets the service life for the specific system.
Will my house look different?
Yes, if it was brick or pebble dash. If you want to keep a brick look, a brick-slip finish over the insulation is an option.
Does insulated render need painting?
Through-coloured silicone and acrylic renders don't need painting. Mineral renders are usually painted with a compatible masonry paint.
