Great Sankey: walls, weather and approvals
We cover Great Sankey and nearby Warrington, Newton-le-Willows and Widnes. Great Sankey is about 2 miles from Warrington. The North West has one of the largest stocks of pre-1919 solid-wall terraces in England, alongside Pennine stone houses and post-war estates.
Exposure to wind-driven rain varies across Cheshire: 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 Great Sankey, grey EPS can sometimes avoid the cost of extending the roofline.

Approvals in England
For a house in Great Sankey, external insulation or render is often permitted development if it looks similar to the existing walls; conservation areas, flats, commercial buildings and listed buildings need permission or consent, so we check your address first.
Building control applies once more than half of a wall is insulated or re-rendered, or more than a quarter of the whole building envelope, and your written quote says how that's handled.
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 Great Sankey: 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.
Is EPS insulation safe on a house?
EPS is used inside render systems that are fire-tested as a whole. On low-rise houses it is widely used. On taller buildings, or where guidance calls for non-combustible materials, mineral wool systems are specified instead.
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.
