Wood fibre insulation for older homes in Antrim
Homeowners and landlords in Antrim can get a free survey and a fixed written quote for wood fibre external wall insulation, covering BT41 and the surrounding area. If your home in Antrim is in a conservation area, we check the council's position on render before suggesting wood fibre EWI.
- Free survey in BT41 and nearby
- Guide price from £150 per m² + scaffold, 0% VAT

Postcode, service and a phone number is all we need.
Included as standard
- Compatible with lime renders used on traditional buildings
- Vapour-open and hygroscopic — buffers moisture rather than trapping it
- Often the most suitable EWI where planning allows on older properties
- Thicker than foam for the same U-value
Antrim: walls, weather and approvals
As well as Antrim itself, we quote in Ballymena, Newtownabbey and Belfast. Antrim is about 14 miles from Belfast. Northern Ireland has many rendered and pebble-dashed homes, older solid-walled rural houses, and estates built by the Housing Executive.
Parts of County Antrim 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 Antrim, we look at a wood fibre and lime build-up first.

Planning and building control in Northern Ireland
Before quoting in Antrim, we check whether the property is listed or in a conservation area, which changes what needs planning permission in Northern Ireland.
Building control applies to insulation and major re-rendering in Northern Ireland, and the work is signed off by the council.
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 Antrim: 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.
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.
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 Antrim?
Yes — we survey and quote wood fibre external wall insulation in Antrim (BT41) and nearby Ballymena, Newtownabbey and Belfast, with a fixed written price before any work starts.
