J. C. Seidelin opens the first dedicated store for building materials at Fredens Torv in Aarhus.
Louis Hammerich takes over the business and expands the range to include wholesale products and begins to import building materials from abroad.
L. Hammerich Specialforretning i Bygningsartikler is renamed Aktieselskabet L. Hammerich & Co. The public limited company has registration number 645 and is thus one of the oldest surviving public companies in Denmark.
The business has grown, and A/S L. Hammerich & Co. moves into modern new premises in Grønnegade in central Aarhus. Poul Hammerich, Louis’s son, takes over management of the company.
A/S L. Hammerich & Co. acquires A/S Troldhede Pladeindustri in Troldhede. Fibreboard and the cement-bonded wood wool Troldtekt® panels are manufactured here, and a registered trademark is acquired in 1936.
Poul Hammerich sets up the ‘Grosserer L. Hammerich og Hustru Ellen, f. Lisbergs Legat’ foundation to support families and staff. Poul Hammerich dies at a young age, but the foundation is subsequently realised.
Svend Hammerich joins the company management and helps re-establish the company’s position following the Second World War.
The fourth generation of the Hammerich family, Peter Hammerich, joins the company management.
The product range is extensively restructured, with a 100 per cent focus on Troldtekt and a few trade goods. All warehouse facilities are moved to Troldhede, while sales and administration are moved to new offices on Klamsagervej, Åbyhøj. Peter Hammerich leaves the company.
Thorkild Bjerglund Andersen, who has been on the company’s board of directors since 1973, purchases A/S L. Hammerich & Co.
A/S L. Hammerich & Co. moves to the sawmill Aarhus Savværk’s former premises on Søren Nymarks Vej in Højbjerg.
Running out of space again, A/S L. Hammerich & Co. moves to the old Østergaard manor in Malling, which Thorkild Bjerglund Andersen has renovated while farming the adjoining land. Huge investments are made in streamlining and modernising production in Troldhede.
The new millennium marks the beginning of a period of strong product development. Troldtekt is no longer just acoustic panels, but acoustic solutions with integrated lighting, sound, ventilation and decoration.
A/S L. Hammerich & Co. and A/S Troldhede Pladeindustri merge under the name A/S L. Hammerich & Co., with sales and administration in Malling and production in Troldhede.
Thorkild Bjerglund Andersen’s heirs take over the company and carry on the family-owned enterprise under the management of a professional advisory board.
Following a business succession, A/S L. Hammerich & Co. moves to more contemporary premises on Sletvej in Tranbjerg outside Aarhus, and the company name is abbreviated to L. Hammerich A/S.
The 75th anniversary of the production of Troldtekt acoustic panels is marked by changing the company name to Troldtekt A/S. Troldtekt receives the Danish Building Industry Environment Award the same year for its focus on the environment and sustainability throughout the product’s entire life cycle.
Troldtekt qualifies for Cradle to Cradle certification in the silver category and prepares a roadmap for developing Cradle to Cradle quality at Troldtekt through to 2022.
The CSR Foundation awards Troldtekt A/S the CSR Awards’ Strategy Prize for its solid and strategic approach to CSR and for having established CSR in all parts of the business, including at executive level and in the business strategy.
Troldtekt Deutschland GmbH is established in Hamburg, the company’s first foreign subsidiary. The strategic focus on neighbouring export markets is followed up by a significant expansion of production capacity in Troldhede.
The company’s second foreign subsidiary, Troldtekt AB, is established in Malmö in Sweden, and production capacity is further expanded.
Troldtekt's production capacity is doubled with the opening of a new 13,000-square-metre production line in Troldhede in western Denmark.
