Glaszentrum Weber + Wagener – glass supplier with in-house production
Glaszentrum Weber + Wagener is a family-run company founded in 1901, now in its fourth generation, headquartered in Freudenberg (Siegerland). The company industrially manufactures multi-pane insulating glass – with a capacity of up to 4,000 units per day – as well as special insulating glass such as fire-resistant glass, Georgian-bar glass, venetian-blind glass, screen-printed glass, cast glass and tinted glass. The product range also includes refined glass products for interior fit-out, including mirrors, glass showers, all-glass doors and walkable glazing made of laminated safety glass, which are processed in an in-house edging shop by edge grinding, drilling, sawing and bonding. In addition, the company offers plastic products such as multiwall sheets, hollow-chamber panels, corrugated sheets and Trespa facade cladding, and through its subsidiary die glaser provides glass installation from measurement to final assembly. From its sites in Freudenberg and Schwalmtal (Lower Rhine) as well as the Wetzlar branch, WWGlas supplies recurring buyers of flat glass products in North Rhine-Westphalia, Hesse and the neighboring Benelux countries. Reference projects range from hotels and trade fairs to industrial customers such as Rittal and Linde.
