Looking for a sprinkler system that is safe and aesthetically pleasing? Then choose a hidden sprinkler system. This fire extinguishing water installation is placed in plastic pipes in concrete, wood or insulation and requires architectural, construction and technical attention. When installing the hidden sprinkler system, materials are used that are compatible with the structural structure and that can withstand structural loads that occur during construction. The right strength, flexibility and tightness are important factors that play a role in the choice of a concealed sprinkler system.
