Spray Foam Insulation FAQs
The National Insulation Association strongly cautions against DIY spray foam setup. Spray foam insulation should constantly be installed by a specialist.
Installers need to be fully trained to apply the foam appropriately and should be evaluated by the British Board of Agrément (BBA- a UK trade body which accredits installers' competence). The spray foam item need to additionally have a BBA certification or matching. The setup should also adapt with the,construction guidelines, and also health and safety guidelines.
