Breathability matters more in Devon's older walls than almost anywhere else, so foil is a roof conversation here, not a wall one.
Exeter's housing and what it means for insulation
Victorian terraces in St Thomas, Heavitree and Newtown, inter-war semis in Pennsylvania and Countess Wear, post-war estates at Whipton and Beacon Heath, and a surrounding county of cottages, cob and slate. Exeter's newer suburbs add 1990s–2010s stock.
Typical Exeter enquiries
- Terrace loft conversions in Heavitree and St Thomas
- Cottage and cob-walled roof build-ups
- Inter-war semi loft rooms
- Loft floor upgrades in Whipton

Older Exeter terraces: shallow rafters and back additions
Heavitree and St Thomas terraces are the conversion stock; the county's cob and stone cottages need breathable, designed roof build-ups rather than a standard detail.
Older roofs can have significantly less usable insulation depth than modern constructions. Rafter dimensions, underlay type, ventilation and any rear or addition roof must therefore be checked at the property before a multifoil or hybrid build-up is specified. Where depth is limited, the usual investigation is multifoil under the rafters with battens forming the room-side air space; where a target U-value applies, PIR between the rafters is added. The party-wall junction and any existing damp staining decide whether the job is straightforward.
Coverage around Exeter
Assessment and installation are allocated by postcode and project type across Exeter and these surrounding areas:
We also cover Cheltenham, Plymouth, Gloucester and the rest of the South West.
How it works, briefly
Postcode → property questions → assessment where a physical inspection is needed → recommendation → fixed quote → installation. Every step runs to the InsulationMatch installation standard; the installing company is named on the quote. Multifoil itself is explained in the multifoil guide, and what moves a price in the cost guide. Local ranges are published here only once genuine Exeter quotes exist.
Local projects
Documented Exeter projects are added to the project library as they complete. Until then the library's typical project scenarios show how the housing above is assessed.
