Headroom under a hipped 1930s roof is the recurring problem, and it is exactly where the multifoil-versus-board question has to be answered by measurement rather than preference.
Solihull's housing and what it means for insulation
Solihull is largely inter-war and post-war suburban: substantial 1930s semis and detached houses in Olton, Shirley and Knowle, 1960s–70s estates in Chelmsley Wood and Marston Green, and higher-value detached stock in Dorridge and Knowle. Loft conversions and room-in-roof upgrades are the dominant enquiry.
Typical Solihull enquiries
- Loft conversions in Shirley, Olton and Knowle
- Room-in-roof upgrades in earlier conversions
- Loft floor and boarding in Chelmsley Wood estates
- Roof-level insulation in detached homes in Dorridge

1930s Solihull semis: the headroom problem
Shirley and Olton semis are converted for a bedroom rather than a study, so the target is a full-height room — which is exactly where the multifoil-versus-board calculation matters most.
Inter-war semi-detached houses here have hipped roofs on purlins whose rafter depth must be measured rather than assumed, and a loft conversion loses headroom quickly if deep board is used. The usual investigation is multifoil under the rafters, with 50mm PIR between them where a target U-value must be met, keeping the finished ceiling as high as possible. The hips, the purlins and the position of the water tank are what the survey measures first.
Coverage around Solihull
Assessment and installation are allocated by postcode and project type across Solihull and these surrounding areas:
We also cover Dudley, Telford, Walsall and the rest of the West Midlands.
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 Solihull quotes exist.
Local projects
Documented Solihull 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.
