Approvals in Scotland
In Scotland, householder permitted development rights are set by the Scottish GPDO and are narrower for external wall changes; insulating flats or tenements, changing the appearance of a house noticeably, or working in a conservation area usually needs planning permission. Listed buildings need listed building consent. Ask your council's planning team before committing.
Work that alters an external wall's construction is covered by the building standards system; many over-cladding projects need a building warrant from the council's building standards team, and Section 6 (Energy) of the Technical Handbooks sets insulation benchmarks.
Scotland restricts combustible external wall cladding on buildings with a storey more than 11 metres above ground, so taller buildings use non-combustible insulation systems.
What about noise?
Dense mineral wool adds mass and absorbs sound, so homes beside main roads or railways often notice a quieter interior, particularly where windows are also upgraded. The improvement depends on the whole wall and windows, so we don't quote decibel figures without testing.

Mineral wool EWI in Dundee and Angus: questions
Can mineral wool EWI have a brick finish?
Yes. Brick slips can be bonded over mineral wool systems designed for them, with additional fixings for the extra weight.
Does mineral wool get wet?
It is water-repellent and protected by the render system. Like any insulation it must not be left exposed to rain during installation, so boards are covered and work stops in wet weather.
Is mineral wool needed for a bungalow?
Rarely for fire reasons. It may still be chosen on a damp-prone solid wall where a vapour-open build-up is wanted.
Do you cover all of Dundee and Angus?
Yes. We survey and quote mineral wool external wall insulation across Dundee and Angus, including Dundee, Arbroath, Forfar, Montrose.
