„Wall separates, door connects “

– Tammer OÜ

By now Tammer has become the largest project based door factory in Nordic Countries, whose cooperation partners are shipbuilding, construction and real estate maintenance companies, door producers in the Baltic and Nordic countries. Exports account for more than 80% of production.
The idea to create a door company began in 1995 on the ferry Georg Ots, on which two men – complete strangers – decided to order a pizza to share with each other. A mere few months later, the father of a large family with 6 children and the entrepreneur Raigo Tammo founded the family company Tammer that has grown into the largest producer of metal fillers for openings in the Baltic States under the management of the family’s son Anti.

The aim of Tammer
