Lisburn: walls, weather and approvals
We cover Lisburn and nearby Belfast, Castlereagh and Newtownabbey. Lisburn sits around 7 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.
If your home in Lisburn is in a conservation area, we check the council's position on render before suggesting wood fibre EWI.

Permissions in Northern Ireland
For Lisburn homes, the council's planning office has the final say on external changes; conservation areas, flats and listed buildings need an application or consent.
Council building control in Northern Ireland checks insulation work of this kind; the quote says how the application is handled.
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 Lisburn: 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 Lisburn?
Yes — we survey and quote wood fibre external wall insulation in Lisburn (BT27) and nearby Belfast, Castlereagh and Newtownabbey, with a fixed written price before any work starts.
