Particularly inside buildings very strict material requisitions come into application - especially with regard to fire protection. The speedpipe indoor system masters the transition between optimum safety, optimum blowing in characteristics and ease of assembly.
Provision is obligatory - and meanwhile set in stone for the whole European Union:
"The existence of high-speed electronic communications networks up to the end-user should be facilitated [...] in particular by high-speed-ready in-building physical infrastructure. Given that providing for mini-ducts during the construction of a building has only a limited incremental cost [...] all new buildings or buildings subject to major renovation should be equipped with physical infrastructure, allowing the connection of end-users with high-speed networks." (Extract from the EU-Directive 2014/61/EU)
Regardless of legal obligations particularly in apartment buildings or heavily loaded building networks the infrastructure within the building cover must be suitabel for the quick connection to outside.
