130 employees at three Mantua production sites process over 3,000 square metres of monolithic glass and 3,000 square metres of laminated glass per day. Supplying large Italian producers of PVC, wood and aluminium windows, they generated a turnover of 40 million euros in 2022. The company runs a number of production lines over three shifts.
Daniele Predari, Managing Director of Predari Vetri: “We focus on a limited number of major Italian window manufacturers, and our factory is optimized to meet their needs. Our production and logistics capacity allows us to offer 'just in time' deliveries.”
Thermoplastic spacer technology integration
As a company producing high volumes, Predari Vetri started collaborating with Lisec in the early 1980s with an insulating glass line, a profile bending machine and an automatic float glass cutting line with loaders. And this successful cooperation continues to this day.
At the 2022 glasstec trade fair, Predari Vetri decided to invest in the exhibited Lisec insulating glass line with warm edge TPA technology. Mr Predari on the reasons for this decision: “We observe a change in the Italian market regarding customers and products. The share of PVC windows especially in residential construction has grown strongly.”

The Lisec TPA line features a flow measurement system on the applicator head: High precision during the application process ensures consistent end products exactly matching production specifications. After the TPA material is applied, a closing device refines the connection points to achieve not only unit gas tightness, but also a smooth, aesthetic result. The material storage integrated into the machine allows a fast application speed and an uninterrupted production ideal for large volume output.
The value of strategic partnerships
Current governmental tax incentives for residential and public energy renovation make Italy a strong market for IG solutions. To meet customer demand, Predari Vetri founded the Glass Group, established in 2009, a union of 23 leading Italian glass manufacturers that combines decades of experience in the production of insulating glass with high production figures and excellent quality standards. Together, this group operates 28 factories with 900 employees and processes 2,8 million square metres of insulating glass per year, with a turnover of 160 million euros.
