Internal wall insulation in Aberdare
From Aberdare to Rhondda, we price internal wall insulation after a measured survey — no guesswork, and no work starts until the price is agreed in writing. For terraced homes in Aberdare with attractive brick fronts, one approach is to insulate the front internally and the rear externally.

What we look for in Aberdare
As well as Aberdare itself, we quote in Rhondda, Merthyr Tydfil and Pontypridd. Aberdare is about 4 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 plan internal insulation in Aberdare homes room by room so you keep the rest of the house usable.

Permissions in Wales
Internal insulation rarely needs planning permission, but in England and Wales insulating or replastering more than half of a wall's area involves building control, and listed buildings need consent for internal changes that affect their character.
What are the options for internal insulation?
- Insulated plasterboard — PIR or phenolic foam bonded to plasterboard, fixed to the wall and skimmed. Thinnest option.
- Insulated stud wall — a timber or metal frame filled with insulation, with a vapour control layer and plasterboard. Takes more space but runs services easily.
- Wood fibre and lime — breathable boards finished in lime plaster, for older walls that need to manage moisture.

Internal wall insulation in Aberdare: questions
Is internal insulation cheaper than external?
Per m² usually yes, but the cost of moving fittings and redecorating narrows the gap on whole-house jobs.
Can I stay in the house?
Yes, but each room is out of use while it's worked on, typically 3–5 days.
How much room space will I lose?
Usually 50–100mm on each insulated wall, depending on the system.
Do you cover Aberdare?
Yes — we survey and quote internal wall insulation in Aberdare (CF44) and nearby Rhondda, Merthyr Tydfil and Pontypridd, with a fixed written price before any work starts.
