PCA Position on Spray-Foam Insulation

Introduction

The Property Care Association (PCA) is the UK’s principal trade body for building-fabric repair. In late 2021 the PCA issued a cautionary notice regarding spray-foam installations. After a programme of laboratory tests and joint site inspections, the PCA released an updated statement in November 2023 confirming that, when installed by accredited professionals with proper moisture control and ventilation, closed-cell spray foam satisfies all recognised performance and safety criteria.

  • 2022

  • November 2023
    PCA issues a revised position: correctly specified and installed open cell & closed-cell foam is fully compliant.

PCA Homeowner Guidance

  1. Installer Accreditation
    Accredited installers must demonstrate proficiency in moisture management and building physics.
  2. On-Site Quality Assurance Checks
    • Moisture Readings: Pre- and post-installation values must remain below 20 % RH.
    • Confirm continuous coverage and identify any voids.
  3. Comprehensive Handover Pack
    Ensure you receive:
    • Product Safety Data Sheets (SDS)
    • Manufacturer’s warranty documentation
    • A clear maintenance and ventilation plan
  4. Annual Building Inspections
    Arrange yearly checks to detect any subsequent moisture ingress or performance drift.
