Horsham: walls, weather and approvals
We cover Horsham and nearby Crawley, Horley and Haywards Heath. Horsham sits around 7 miles from Crawley. Homes across the South East range from inter-war semis and post-war estates, which are mostly cavity-walled, to older solid-walled cottages and Victorian town terraces.
Exposure to wind-driven rain varies across West Sussex: 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 Horsham enquiry rather than assuming one board suits every wall.

Permissions in England
Planning in Horsham follows England's national rules: similar-looking finishes on houses are usually permitted, while flats, commercial premises, conservation areas and streets under an Article 4 direction need an application.
Insulating or re-rendering more than half of a wall's area brings in Part L of the Building Regulations, so building control is notified and the wall is upgraded to about 0.30 W/m²K where practical.
When is EPS the right choice?
EPS suits most two-storey houses, bungalows and park homes where the wall is sound and there are no fire-height restrictions. It is a good fit where eaves are shallow, because grey EPS can hit the target with less thickness. On buildings with a storey 11 metres or more above ground, or where the guidance asks for non-combustible materials, mineral wool is used instead.

EPS insulation in Horsham: questions
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.
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.
