raumplus manufactures customized sliding doors, room dividers, and closet systems. As a family company headquartered in Bremen/Germany we are able to produce flexibly, from one-off pieces to large quantities.

Our successful history goes back three generations – from the first sliding door, built in 1986 by family head and company founder Jürgen Guddas, through development into a global brand under Carsten and Uta Bergmann (née Guddas) to the illuminated S1200 LED sliding door developed by his granddaughter, industrial designer Nane-Sophie Bergmann, to mark the company’s 30th anniversary. Under the management of current CEO Carsten Bergmann raumplus is today at home in all corners of the globe, with partners in 70 countries, including shares in businesses in the USA, Canada, Russia, Switzerland and Poland. Despite the brand’s ongoing success and growth, raumplus continues to stand for the ethical principles that have been an integral brand component since the company was founded – customer-friendly service, diversity, uncompromising quality, and competence.


With its various range of products raumplus is able not only to produce individual and tailor-made built-in closets and room dividers. raumplus stands for clever and innovative room solutions beyond standards and usual products.

Anyone can follow standards; this has never encouraged us. We have always taken up the challenge to fulfill customer wishes 100%.

We realize anything for our customers, however taking into account fair trading and behavior. We thus attach great importance to follow the credo of our company founder Jürgen Guddas: to be a fair, respectful and honest Hanseatic businessman and to behave in this manner vis-à-vis our suppliers and many qualified employees.

Sustainability - our continual challenge

Maximum product protection with minimum environmental impact – this is our credo when it comes to packaging. It goes without saying that we believe that not only our closet and room divider systems but also our planet’s resources should be protected. To this end, Interseroh GmbH regularly carries out audits based on the Fraunhofer Institute’s UMSICHT study to identify how much of a contribution recycling of our transport packaging is making to saving primary resources and avoiding greenhouse gas emissions. The »resources SAVED by recycling« study and our personal Resource Protection Certificates confirm that we were able to achieve new best performances over the last years. For example: by returning raumplus packaging to the recycling flow we were able to avoid 20,903 kilograms of greenhouse gases and save 177 metric tons of resources in 2016. This is equivalent to the weight of 417 apple trees – an image that is as inspiring as it is interesting and motivates us to continue to work hard to act responsibly. Towards our customers and the environment.


We use cardboard instead of foils or foams for our packagings as far as possible. 80% of the produced corrugated board already consists of recycled paper. Cardboard packaging waste is shredded and used as filling material.


As far as flights cannot be avoided, we pay attention to low-emission flight bookings.

LED Lamps

We are saving global warming gases by switching to LED lamps in our offices, production and warehouse.


The corrugated board we use for our packaging is 100% recyclable.

Printing products

Our main brochure »Smart Sliding & More« is printed climate-neutral and with FSC certified paper.

Image pictures
