Local considerations in Trowbridge
As well as Trowbridge itself, we quote in Bath, Frome and Chippenham. It's roughly 25 miles from Trowbridge to Swindon, the largest town in Wiltshire. The South West has many stone and solid-walled cottages, exposed coastal properties and a share of post-war system-built houses, including types such as the Cornish Unit.
Exposure to wind-driven rain varies across Wiltshire: 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 Trowbridge, we look at a wood fibre and lime build-up first.

Planning and building control in England
For a house in Trowbridge, external insulation or render is often permitted development if it looks similar to the existing walls; conservation areas, flats, commercial buildings and listed buildings need permission or consent, so we check your address first.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.
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 Trowbridge: questions
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.
Does wood fibre need a lime render?
It needs the render specified by the system manufacturer, which is usually lime or mineral based.
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 Trowbridge?
Yes — we survey and quote wood fibre external wall insulation in Trowbridge (BA14) and nearby Bath, Frome and Chippenham, with a fixed written price before any work starts.
