Homes and walls in Perth
We also cover Blairgowrie and Crieff, close to Perth. Tayside has stone tenements and terraces in the towns, harled cottages and post-war estates.
Exposure to wind-driven rain varies across Perth and Kinross: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.
We compare EPS against mineral wool for each Perth enquiry rather than assuming one board suits every wall.

Planning and building control in Scotland
For Perth properties, flats and tenements need planning permission for external insulation, and a noticeable change of finish on a house often does too under Scottish rules.
Scotland's building standards cover changes to external wall construction; we check whether your job in Perth needs a warrant.
How thick does the board need to be?
On a 225mm solid brick wall, around 90mm of grey EPS or 100–110mm of white EPS typically gets close to 0.30 W/m²K. Stone walls, concrete panels and hollow-block walls start from different points, so the system supplier's calculation for your wall sets the final thickness.

EPS insulation in Perth: questions
White or grey EPS?
Grey graphite EPS insulates better per millimetre, so it is the pick where space is tight at the eaves or around windows. White EPS is slightly cheaper and works well where the extra thickness isn't a problem.
How long does EPS last on a wall?
The board itself doesn't degrade when protected by the render system. Service life depends on the render, sealants and detailing, typically 25–30 years or more with maintenance.
Will woodpeckers damage EPS?
It happens occasionally, especially near woodland. Damage is to the render and board surface and is repaired with a mesh patch and colour-matched finish.
