Re-Insulation Options
After spray foam removal, we specify breathable, high-performance re-insulation — typically reflective multifoil systems (e.g., SuperFOIL®) — designed to keep heat in, let moisture escape, and keep roof timbers visible for inspection. That means comfort, lower bills and a roof lenders and surveyors can sign off with confidence.
Why choose reflective multifoil (e.g., SuperFOIL®)
Radiant barrier
Reflects radiant heat to reduce heat loss in winter and heat gain in summer for steadier indoor temps.
Built-in vapour control
Integrated VCL helps minimise moisture ingress and condensation risks when detailed correctly.
Breathable build-ups
Designed with proper ventilation paths so moisture can escape — supporting timber health.
Slim & lightweight
Space-efficient compared to bulky rolls — ideal where headroom matters.
Fast installation
Clean, quick installs help reduce disruption and labour time.
Mortgage-safe approach
Timbers remain inspectable with photo documentation for lenders/surveyors.
SuperFOIL’s multifoil range combines reflective foils, wadding and a vapour control layer to deliver insulation + radiant barrier performance in a slim build-up.
Popular options we install
EPC improvements and property value
EPC uplift
Better insulation contributes EPC points; many homes see meaningful score gains when roofs are upgraded and detailed correctly.
Buyer appeal
Greener, lower-running-cost homes attract more interest; higher EPCs are associated with price premiums in market studies.
Mortgage readiness
Post-foam, a breathable, inspectable roof simplifies surveys and lender queries — reducing sale friction.
Why multifoil — and not just a breathable membrane?
Insulation vs underlay
A membrane manages moisture/air but isn’t insulation. Multifoil adds real thermal performance and a radiant barrier.
Timber health
With correct ventilation detailing, multifoil helps moisture escape while keeping timbers inspectable.
Comfort & bills
Reflective layers reduce heat loss and summer heat gain — improving comfort and cutting energy waste.
We often specify multifoil with ventilation baffles and, where needed, a hybrid with rolls/PIR to hit target U-values.

FAQs
Is multifoil right for every roof?
We design to your roof build-up. Some homes benefit from a hybrid (foil + rolls/PIR) to reach target U-values while keeping the roof breathable and inspectable.
Will this help my EPC?
Improving roof insulation typically increases EPC points; the actual uplift varies by property and other measures in place. We’ll advise what’s realistic for your home.
How long does installation take?
Most re-insulation projects are fast once the roof is prepared — we’ll confirm timings after survey.
