Kumal S is a private company founded in 2004, which operates within the Kufner Group, and its main activity is the production of expanded polystyrene (EPS) and sandwich thermal insulation panels.

Since 2008, in addition to the production of EPS, Kumal has been emphasizing the production of sandwich thermal insulation panels with EPS and stone wool filling.

That is why Kumal takes care of a stimulating work environment. We provide appropriate working conditions in which our employees can find an opportunity for their professional and personal development.

As a manufacturer of high quality EPS products in the market, we need to be in line with trends and focused on change and development.
