Local considerations in Aberystwyth
We also cover Llandrindod Wells and Newtown, close to Aberystwyth. Aberystwyth is about 51 miles from Llanelli. West Wales has a high share of older solid-walled and stone homes, many in exposed coastal or rural settings.
Parts of Dyfed 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.
For older stone and early brick properties in Aberystwyth, we look at a wood fibre and lime build-up first.

Wales: planning and regulations
We check Aberystwyth 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.
Why do older walls need breathable insulation?
Stone and early brick walls were built with lime mortars and renders that let moisture in and out. Sealing them with impermeable materials can trap water in the wall, leading to damp and frost damage. Wood fibre keeps the build-up open to vapour, and its ability to absorb and release moisture helps the wall stay in balance.

Wood fibre EWI in Aberystwyth: questions
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.
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 Aberystwyth?
Yes — we survey and quote wood fibre external wall insulation in Aberystwyth (SY23) and nearby Llandrindod Wells, Newtown and Carmarthen, with a fixed written price before any work starts.
