Local considerations in Newport (Gwent)
We also cover Risca and Cwmbran, close to 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 older stone and early brick properties in Newport (Gwent), we look at a wood fibre and lime build-up first.

Approvals in Wales
We check Newport (Gwent) addresses for conservation areas and listing before quoting, because Welsh permitted development rules don't cover every external change.
In Wales, insulating or re-rendering more than half of a wall's area is treated as renovating a thermal element under Approved Document L (Wales), so building control is involved before work starts.
What finish goes over wood fibre?
A lime-based or mineral render designed for the system, applied over a reinforcing base coat. Lime finishes give the softer, slightly irregular texture that suits cottages and older terraces.

Wood fibre EWI in Newport (Gwent): questions
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.
Is wood fibre worth the extra cost?
On older solid walls the main benefit is moisture safety rather than raw U-value. If the wall needs to breathe, the cheaper option can cost more later.
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.
Do you cover Newport (Gwent)?
Yes — we survey and quote wood fibre external wall insulation in Newport (Gwent, NP20) and nearby Risca, Cwmbran and Pontypool, with a fixed written price before any work starts.
