The mission of the “Ostrowski” company is to build a leading position in the production of sandwich panels for joinery on the Polish market, and to develop a network of customers on European markets. We also try to use our experience in acquiring new market segments by offering innovative solutions using sandwich panels in which the core is extruded polystyrene (XPS).

In 1991 Mr. Krzysztof Ostrowski establishes a construction company dealing with, among others, construction works in the field of thermal insulation of housing estates, renovation of banks, schools and other facilities. In response to economic changes and interest of market, the company also conducted commercial activities in the RTV (1993-1997) and catering (1999-2004) industries.
In 2003, while looking for new areas of economic activity, a production line of sandwich panels for door panels was launched. The new business profile is run as a commercial law company called “Ostrowski” Sp. z o.o.
Due to the high quality standards imposed by the owner and an efficient trade policy, the company is gaining part of the domestic market within a few years and is also successful in exporting to Central and Eastern Europe. The company’s trading partners are mainly domestic and international wholesale networks.
Thanks to the energy market’s interest in ecological fuel, new business opportunities have emerged.
In 2008, “Ostrowski” acquires real estate near the intersection of A1 and A4 motorways and builds a reloading and warehouse base for mass products. The company has the appropriate equipment base, automotive fleet and warehouse halls. Regardless of reloading and storage of biomass, the company also conducts online retail sales of ecological fuel.
As part of the capital group, there has also been a company operating in the Internet trading in lighting, electrical equipment and accessories since 2006 (www.LuxMarket.pl).
The company’s development strategy in the coming years provides for further diversification of business activities within the capital group, in particular the expansion of the hardware base and infrastructure as well as undertaking projects in the field of “green” energy.
