Insulation

Today, the world has a heightened understanding of the importance of energy-efficient products. Consumers are more aware of energy ratings, carbon savings and the thermal benefits available. This continues to drive the need for greater thermally-efficient and cost-effective solutions, to reduce the carbon footprint of our buildings. BBA Test Services perform a wide range of tests on a variety of insulation products, including rigid boards, foam, multi foils, loose bead and fibre for use in wall, floor and roof applications.
