INNOVATION FROM MORE THAN 30 YEARS OF EXPERIENCE
Dennert Poraver GmbH is the global market leader in the manufacture and sales of expanded glass granules. The company is among the pioneers in the field of innovative lightweight filling materials. More than 30 years ago, in our own research, a method for the industrial manufacture of expanded glass from recycled glass was developed – a milestone in the company’s history.
Since then, the company, founded in 1983, has manufactured the lightweight aggregate Poraver® expanded glass granules at its production sites in Europe and North America for customers and distributors throughout the world.
