Barnstaple: walls, weather and approvals
We also cover Bideford and Exeter, close to Barnstaple. Barnstaple is about 49 miles from Plymouth. The South West has many stone and solid-walled cottages, exposed coastal properties and a share of post-war system-built houses, including types such as the Cornish Unit.
Parts of Devon 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.
We compare EPS against mineral wool for each Barnstaple enquiry rather than assuming one board suits every wall.

Permissions in England
Before quoting in Barnstaple, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.
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 Barnstaple: 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.
