This service combines aspects of fire safety with general building performance. While primarily focused on preventing the spread of smoke (which is the main cause of fatalities in fires), the techniques used often also create barriers for sound and odours.

This involves meticulous sealing of gaps, joints, and penetrations using specialized sealants and materials that are impermeable to air, smoke, and sound waves. For example, acoustic sealants used in firestopping applications can reduce noise transfer between rooms while simultaneously providing fire resistance. This holistic approach enhances both the safety and comfort of building occupants.
