Homes and walls in Thurso
As well as Thurso itself, we quote in Wick, Kirkwall and Lossiemouth. Thurso is about 81 miles from Inverness. The Highlands and Islands have many exposed stone and harled homes, timber-framed houses and scattered rural properties.
Parts of Highland 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 Thurso is in a conservation area, we check the council's position on render before suggesting wood fibre EWI.

Approvals in Scotland
In Scotland, permitted development for external wall changes is narrower, so in Thurso we check with the council's planning team where the appearance changes, and always for flats, tenements and conservation areas.
Over-cladding work in Scotland often needs a building warrant from the council's building standards service, with Section 6 of the Technical Handbooks setting insulation benchmarks.
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 Thurso: 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.
Does wood fibre need a lime render?
It needs the render specified by the system manufacturer, which is usually lime or mineral based.
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 Thurso?
Yes — we survey and quote wood fibre external wall insulation in Thurso (KW14) and nearby Wick, Kirkwall and Lossiemouth, with a fixed written price before any work starts.
