Before we quote in Pontypool
We also cover Cwmbran and Risca, close to Pontypool. It's roughly 8 miles from Pontypool to Newport (Gwent), the largest town in Gwent. South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Exposure to wind-driven rain varies across Gwent: 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.
Where eaves are shallow on a house in Pontypool, grey EPS can sometimes avoid the cost of extending the roofline.

Permissions in Wales
Householder rules in Wales are similar to England's: in Pontypool, a similar-looking finish on a house is often permitted, but conservation areas, flats and listed buildings need permission or consent.
Building control in Wales applies to most insulation and re-rendering jobs of this size; the quote states who submits the notice.
What is EPS insulation?
Expanded polystyrene is a closed-cell foam made from beads that are expanded and moulded into boards. White EPS is the standard grade; grey EPS has graphite added, which reflects radiant heat and improves performance by roughly 15–20%, so a thinner board does the same job. Both are used inside certified render systems where the board, adhesive, fixings, mesh and finish are tested together by the manufacturer.

EPS insulation in Pontypool: questions
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.
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.
