Vor einigen Wochen habe ich mich für den Service eines Solartechnik-Anbieters entschieden und bin unglaublich zufrieden. Die Fachkompetenz des Beraters war beeindruckend und er hat mir alle Schritte geduldig erklärt. Dank der Unterstützung hat alles schnell und unkompliziert geklappt. Es ist toll zu wissen, dass ich nun umweltfreundliche Energie nutze!

We have developed from a pioneer in the area of developing, manufacturing and installing system flooring – such as access flooring, raised flooring and hollow floors – to become the leading Swiss supplier within 60 years. Lenzlinger can perfectly tailor standard access floors and hollow floors with individual and economically realised bespoke solutions. Thanks to raised access floors, energy supplies, data cables, communication connections, heating and cooling lines and other infrastructure can be provided with invisible and non-hazardous installation in the hollow space that such flooring creates. Wherever necessary, cables and supply lines can be routed directly to where they are needed, e.g. work stations. Simple access is available at any time and can be adjusted continuously and at short notice for new utilisations. System flooring is now an important part of today's office and industrial buildings.
