Competent by tradition - Novapor since 1958

When Hans Lau founded the Novapor company in 1958, he wanted to create a company that stood for reliability, innovation and consistency. A brave step in difficult times, but this vision paid off. Novapor is now successfully managed by the third generation and can look back on a great history.


Novapor's company founder Hans Lau was born in Kollmar in Dithmarschen.

Already after the 2nd World War the merchant is quite successful with shops in Hamburg.

Just 6 years later, Hans Lau founds the company Novapor. The first seat of the company is in Hamburg Lokstedt. Styrofoam blocks are foamed there and insulating panels are cut.

In addition to the production of normal insulating panels, the focus of the company will then be on building cold rooms.



Hans Lau can benefit from the many contacts he has with fruit growers and tree nurseries through his birthplace Kollmar.

The Novapor company and the name Hans Lau are now quickly becoming a good name when it comes to the insulation of cold rooms and warehouses.


Since the Hamburg location soon ran out of space, Hans Lau builds the first production facility on his own premises near his home in Garstedt.

Hans Lau makes the first attempts in the area of EPS molding production and creates an automatic molding machine and an EPS cutting line.



Company founder Hans Lau dies at the age of 68. The sons-in-law Günther Mühlenberg and Herbert Hildebrand take over the management. The oil crisis hits the company hard in the 1970s, as the raw material produced from crude oil is allocated to the processing companies.


In addition to styrofoam, polyethylene is now also being processed and successfully sold.

Discontinuation of the production of molded parts and further expansion of the production of blanks and special parts.

The polystyrene range is expanded to include qualities from 11 kg/m³ to 60 kg/m³. Block dimensions of up to 4 meters in length are processed.

Unfortunately, since this space does not last long, another warehouse is rented in the vicinity.

The good business and order situation requires the construction of a new warehouse in Norderstedt. Managing Director Herbert Hildebrandt retired in 1997.

A year later, Managing Director Günther Mühlenberg retires. However, he continued to support the company in an advisory capacity until the year 2000.
