Local building codes in the United Kingdom include specific instructions for the installation of spray foam insulation in roof structures. Fireproof paint regulations in the UK do not require a thermal barrier between SPF and occupied spaces. That said, many insulation installers do choose to coat their foam in fire retardant spray or fireproof paint and fire safety is an ongoing conversation among contractors.
Insulation Manufacturers Association (IMA) Overview
The Insulation Manufacturers Association (IMA) is the UK trade association representing the polyisocyanurate (PIR) and polyurethane (PUR) insulation industry. Members include major manufacturers of rigid insulation, which constitutes about 40% of the UK’s total thermal insulation market, as well as suppliers of raw materials and related services. IMA advocates for the industry’s interests to government and other stakeholders, promoting a favorable business environment for PIR and PUR insulation.
Spray Foam Insulation (SPF) Installation Guidelines According to IMA
UK regulations specify that SPF insulation should not be installed by anyone other than a registered, trained and approved installer. Any spray insulation product must have a third-party certificate such as a BBA certificate or Kiwa BDA Agrément®, ensuring its suitability for the intended application.
The British Board of Agrément (BBA) drives industry safety by providing services that help clients create accountability and mitigate risk. Since 1966, the BBA has built its position as an independent certification body in the Construction and Civil Engineering Industries.
The Kiwa BDA Agrément® process is designed to underpin the “safety and fitness for purpose” of products destined for the UK construction market. Products are examined and rigorously tested following precise installation instructions. Agréments confirm the compliance and durability of the product under the specified method of installation.
UK Regulations for Installing SPF on Roof Space
Reoccupation of the roof space should be delayed for 24 hours unless a forced ventilation system (30 air changes per hour) is used, reducing the wait time to two hours. Follow the manufacturer’s specific guidelines for ventilation and reoccupation.
Chemical Storage and Handling of SPF
SPF chemicals must be stored in a secure, cool, and ventilated area, away from direct sunlight and incompatible materials. Ensure containers are tightly sealed to prevent moisture contamination, which could cause drum rupture due to carbon dioxide gas formation.
SPF Clean-Up and Maintenance
Post-application clean-up requires appropriate PPE. Remove PPE in a designated clean zone and dispose of contaminated items according to regulations. Inspect and clean reusable PPE, and properly decontaminate or dispose of contaminated items.
Spills and Emergency Procedures when Working with Spray Polyurethane Foam
Have an emergency spill kit ready. In the event of a large spill, evacuate personnel, call emergency services, and prevent the spill from entering drains. Follow the Safety Data Sheet’s instructions for clean-up and disposal and report the spill if required.
Disposal of SPF Chemicals
SPF chemicals are classified as hazardous waste and must be disposed of according to national regulations. Consult the manufacturer for disposal advice for large quantities.
Health and Safety for Spray Foam Insulation Installers
Access to the work area should be limited to trained personnel wearing the required PPE. After installation, provide the homeowner with a pack detailing the installer, installation date, product type, certification details, photographs, pre-installation survey, condensation risk analysis, and warranty information. An abbreviated version should be left in the loft space.
