Surface-related advice and large-scale projects – you can count on our many years of specialist skills

Over the past years Jansen has enhanced its service spectrum by the surface-related advice and large-scale projects sector. This includes surface-related advice for any technical issues surrounding our systems and non-standard solutions. Thanks to Jansen you as the architect, specialist planner, building owner or fabricator can rely on a strong partner by your side to support you throughout all performance phases from planning to implementation.

A unique component develops with each building project featuring individual edge conditions and resulting technical requirements. With our technical support we are happy to support you in mastering these challenges – be it with design suggestions, static and/or thermal calculations or performance certificates as part of component tests at our technology centre.
