Seals and Insulation

For more than 70 years, Planet lowering gaskets have made threshold-free doors seal against the ground. It all started in a carpentry shop in Zurich. Here they worked out the first Planet drop-down seals for doors and developed them continuously.

The effect was not long in coming, conquered but the carpenters with the Planet Absenkdichtungen a market niche. Finally, the production of the Planet Absenkdichtungen was outsourced and sold in 1998. 

This change of ownership resulted in today's Planet GDZ AG based in Tagelswangen, Zurich. Now the innovative owners, René Gyger and Andreas Dintheer, successfully continue the company history of the company.
