IGNIS / PASSIVE FIRE PROTECTION

Protection.
Built in.

Specialist passive fire protection
for the built environment.

01 / BENEATH THE SURFACE

The protection
you don’t see.

Behind the finished façade.
Within the structure. Between spaces.
Protection, carefully integrated.

02 / STRUCTURAL PROTECTION

Strength.
Protected.

Intumescent coatings protect structural steel. Fire-rated board encasement provides another route, selected to suit the specification.

INTUMESCENT COATINGS / ENCASEMENT

03 / SERVICE PENETRATIONS

Every opening.
Considered.

Pipes and cables pass through walls and floors. Fire-stopping systems protect the integrity of those boundaries.

FIRE STOPPING / MASTIC SEALS

04 / COMPARTMENTATION

Protection
between spaces.

Fire barriers continue the line of protection through concealed voids. The details matter, even when they disappear from view.

FIRE CURTAINS / BARRIERS

05 / THE COMPLETE PICTURE

Individual details.
One purpose.

Specialist passive fire protection,
from the structure to the smallest junction.
