Foil and multifoil insulation inspection
Foil and multifoil products perform as published only when fitted the way their product approval says: a ventilated air gap on the right side, sealed joints, the vapour control where it should be. This inspection records whether yours was.
- Independent
- £295
- Travel included within ~3 hrs of the North West
- Report in 48–72 hours
Travel included within about three hours of the North West; a fixed supplement further away, shown with your total before you book.
Independent: SprayFoamCheck doesn't install or remove insulation and takes no referral fees.
Book this one if
- Multifoil was fitted under the rafters, often after spray foam removal, and you want to know whether it was done properly
- The loft is damp or there's condensation on the foil
- A surveyor couldn't confirm what was installed or how, and a sale or application has slowed
- You suspect the product in the loft isn't the one on the paperwork
What's included for £295
Included
- Multifoil product identification where possible (SuperFOIL, YBS, Actis, generic)
- Installation cross-referenced against the relevant BBA product approval
- Air gap, sealed-joint and vapour control checks
- Combined insulation buildup vs claimed U-value
- Moisture meter + psychrometer readings as standard
- Photo-referenced written report
What it isn't
- Removal or installation work
- Legal or financial advice
A product approval covers the product under defined conditions; it doesn't confirm that the material in your loft was fitted to those conditions. That's what the inspection looks at. It isn't a report for a lender, and no one can promise what a lender will do.
Travel is included within about three hours' drive of the North West base. Further away, a fixed travel supplement is added (£50 South & East England, £75 Greater London, £100 far Cornwall) and shown with your total as soon as you enter your postcode, before you book. Express delivery (+£50) is 24 hours from the visit. Questions after the report are free.
