The advantages of sprinkler systems for fire protection

Fire sprinklers are a tried and tested fire suppression technology that is used worldwide to save lives and protect property. 

Sprinklers offer some unique advantages over other fire protection methods for all properties, including:

Improved coverage in spaces over 4.5m – sprinkler installation removes the requirement for a separate exit in the event of a fire and for extra smoke detection devices.

Removal of the need for self-closing doors – self-closing bedroom doors can be hazardous for vulnerable residents in care homes. The security provided by fire sprinklers means that they are not necessary. 

Safer open-plan spaces and fewer doors in corridors –  the distance between doors in corridors can be increased making it easier for residents to get around. 

Increased accessibility for fire appliances – sprinkler protection means that fire appliances can be effective from 60m rather than 45m distance from your property.

Types of sprinkler systems

Modern sprinkler heads are designed to use inert gases, chemical gases, aerosol foam, carbon dioxide or water vapour.

Most of our residential clients choose mist systems for their properties.

When a water mist system is operational, the sprinkler heads produce tiny drops of water at high pressure. In hot conditions, the water turns into a cooling vapour, which can quickly suppress fire across a large area.

Clients protecting valuable stock or server rooms often choose inert gas or similar to avoid the potential water damage from a water-based system.
