Yes, all of our engineers go through rigorous in-house training, ongoing audit processes and are fully certified to install the iMist system.
The mess will be minimal, and all of our engineers are trained and instructed to clear up after they have installed the system.
Our system is designed to be fitted behind a 30-minute fire resistant plasterboard barrier. If you cannot provide us with this, then we would install solid fixed stainless-steel pipework. This pipework is, however, very small compared to a typical fire sprinkler system.
Typically, a 5 nozzle system could be fully installed in half a day.
Yes, our system is easily retrofitted within existing buildings/developments. The iMist system is installed much easier than traditional systems because of the flexibility of its components.
We have completed many retrofit projects 
Each nozzle covers 16m² or 172 sq. ft, so it would depend on how many rooms are in the property, as well as the size of the rooms.
The pump unit is designed to fit in kitchen units under the sink, in under stairs cupboards, the eaves of the building etc.
