What the job covers
- Thicker than foam for the same U-value
- High density gives good protection from summer heat
- Vapour-open and hygroscopic — buffers moisture rather than trapping it
- Often the most suitable EWI where planning allows on older properties
Risca: walls, weather and approvals
As well as Risca itself, we quote in Newport (Gwent), Cwmbran and Caerphilly. Risca sits around 5 miles from Newport (Gwent). South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Exposure to wind-driven rain varies across Gwent: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
For period homes in Risca, the survey looks closely at existing lime mortars and any cement patching that may trap moisture.

Permissions in Wales
We check Risca 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.
What about listed buildings and conservation areas?
EWI on a listed building needs listed building consent and is often refused where the outside appearance matters. In conservation areas, rendering or cladding a house normally needs planning permission. Wood fibre and lime are more likely to be acceptable than foam and acrylic, but the council decides. We check before quoting.

Wood fibre EWI in Risca: questions
Does wood fibre need a lime render?
It needs the render specified by the system manufacturer, which is usually lime or mineral based.
Is wood fibre insulation fireproof?
No — it's a timber product. It chars rather than flaming readily, but it is combustible, so it's used on low-rise buildings within a tested system and never where non-combustible materials are required.
Can wood fibre go on a stone wall?
Yes, after levelling. Rubble stone is often uneven, so a levelling coat or adapted fixing method is used first.
Do you cover Risca?
Yes — we survey and quote wood fibre external wall insulation in Risca (NP11) and nearby Newport (Gwent), Cwmbran and Caerphilly, with a fixed written price before any work starts.
