History of the PV Group The PV Group is a group of companies that specialise in Perlite and Vermiculite. We have been working with these minerals for more than 25 years. Currently, our business activity ranges from perlite and vermiculite expansion to subsequent applications (manufacturing mortar for fireproofing, soundproofing, heat and cryogenic insulation and and lightweight mortars). The main feature of these materials is their low heat conductivity, which makes them the best natural insulators around. They are suitable for all kinds of insulation, including fireproofing, soundproofing, heat and cryogenic insulation, etc.… Our business activities focus on: Manufacturing expanded perlite and vermiculite for construction, industry and agriculture. Manufacturing systems for passive fire protection in factories (chemical, petrochemical) and buildings. Manufacturing acoustic absorption systems. Manufacturing lightweight mortar. Applying our products on-site. Cryogenic insulation.
