Thurso: walls, weather and approvals
We cover Thurso and nearby 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.
For terraced homes in Thurso with attractive brick fronts, one approach is to insulate the front internally and the rear externally.

Planning and building control in Scotland
Internal insulation rarely needs planning permission; listed buildings need consent for internal changes.
Where a building warrant is needed for Thurso work, it's obtained before installation starts, and the quote says who arranges it.
What are the risks with internal insulation?
Insulating inside makes the masonry colder, so moisture risk rises. Weak points are where floor joists bear into the wall, window reveals and corners. A condensation risk check for the build-up, a continuous vapour control layer where specified, and returning insulation into reveals deal with most of it.

Internal wall insulation in Thurso: questions
How much room space will I lose?
Usually 50–100mm on each insulated wall, depending on the system.
Is internal insulation cheaper than external?
Per m² usually yes, but the cost of moving fittings and redecorating narrows the gap on whole-house jobs.
What happens to my radiators and sockets?
They're taken off and refitted on the new wall face. Electrical work is done by a qualified electrician.
