Home Fire Suppression Systems for your Extension

Looking to extend your property? Protect your home and your family with a mist fire suppression system and ensure you comply with building regulations.

Unrivalled Protection for Homeowners

Home extensions, including kitchen extensions and loft conversions, are relatively cost-effective, providing your home with additional room at a much lower cost than purchasing a new property. Open-plan living, although visually pleasing, can lead to a fire spreading rapidly. In most cases, a home fire suppression system is installed to protect afford valuable extra time for occupants to escape, as well as protecting the property in the event of a fire.

When extending your living space, several building regulations will need to be considered to ensure that your property is fully compliant. Thanks to the flexibility of the iMist™ fire suppression system, we can easily retrofit in a cost-effective, quick and clean way, avoiding unnecessary disruption to your home.

Why Do You Need a Home Fire Suppression System?

BS:9991 says you must have an AWFSS in the following circumstances; Multi-Basement Buildings

For dwellings with multiple floors below ground level, a protected stairway, and an AWFSS is required. 9 meters should not be exceeded from the foot of the protected stair to any habitable room.

A second, separate protected stairwell is not required if AWFSS is fitted throughout.

Flats or maisonettes with an open plan arrangement and more than one floor should have a protected stairway and AWFSS fitted. This allows escape to the shared external entrance.

Flats more than 4.5m above ground level that are entered on the same level can increase total travel distances to the entrances from 9m to 20m with the
