The Construction Products Association acts as a single voice to promote and campaign for construction product manufacturers and suppliers in the UK.
The construction products industry is at the heart of the UK economy, providing essential materials for the built environment including our homes, schools, hospitals, factories, offices, roads, railways and other infrastructure.
