Brecon: walls, weather and approvals
We cover Brecon and nearby Merthyr Tydfil, Ebbw Vale and Aberdare. Brecon sits around 39 miles from Newtown. Mid Wales is largely rural, with stone farmhouses, cottages and market-town terraces, many of them solid-walled.
Parts of Powys 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.
EPS is a common choice for two-storey houses, mainly on cost and weight, and we price it alongside mineral wool for homes in Brecon.

Wales: planning and regulations
Householder rules in Wales are similar to England's: in Brecon, a similar-looking finish on a house is often permitted, but conservation areas, flats and listed buildings need permission or consent.
In Wales, insulating or re-rendering more than half of a wall's area is treated as renovating a thermal element under Approved Document L (Wales), so building control is involved before work starts.
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 Brecon: 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.
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.
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.
