About us


AS Klaasmerk was founded in 1992 as a sheet glass processing and installation company. In March 1993, we became one of the first insulating glass unit (IGU) manufacturers in Estonia. The manufacturing of IGUs has remained our principal activity to this day.

  • We have represented the U.S.-based Tremco illbruck Group in Estonia since 1995.
  • In 1998, we received the EN 1279 certificate for the production of IGUs, which certifies that our products conform to the IGU quality requirements under the standard.
  • In 2000, we merged with AS Klaasimaailm, which allowed us to expand our range of products with various types of interior design and safety glass, mirror sliding doors, and a variety of glass processing methods.
  • In 2008, we merged with AS Plastmerk, adding plastic door and window profiles to our selection of products.


Today, Klaasmerk is a recognised glass processor and door and window manufacturer with one of the widest ranges of products in Estonia, serving both private and business customers. We value innovation and offer both simpler as well as more complex custom solutions. We value quality and work to a high standard in even the smallest of jobs.

Our site is located at Valdeku 132, Nõmme, Tallinn with a production area of 4,100 m2.
