Copper is safe
Even if you decide not to fit your house with a sprinkler system, installation tubes made of copper can save your life in case of fire. Copper tubes are non-combustible and release neither fumes nor toxic gases.
Most of all, copper is sustainably safe. All tubes and connections are manufactured according to international standards. This means that all components are always available - or at least have the shortest possible delivery periods - and fast work for the installer because he needs no specialist tools for installation. This is something that cannot be said for many other tube systems.
