In a tough group can be grown into a success


HSL Group has specialized in partition wall systems and we are this industry's leading companies in Finland. Our success is born out of a complete service, that starts from the building property's designing phase and continues from the property's putting in service to the transformation of the spaces throughout the whole lifecycle of the property. Which means that we work in cooperation with architects, developers, construction companies, as well as the property owner and the users of the premises.

The values of our work is, quality, cost-efficiency, ecologicality and domesticity.

Important part of our work is domestic expertise. All of our walls are designed and made in Finland, Heinola. We look after our 25 employees. We know that a good, or even an excellent product is not enough alone. That's why we continuously invest also in customer satisfaction and the development of service concepts.

As last point we would like to bring up the respecting of the environment. Our business is guided by the principles of sustainable development, and we want to take into account in all of our work also the upcoming generations. We expect this also from our own partners.
