For any passive fire protection system, air leakage can act to compromise it’s effectiveness, leading to an increased ability of fire and smoke to penetrate through services and spread throughout a building.
With an increased focus on energy efficiency and sustainability in construction, driven by motives such as BREEAM and compliance with Part L of the Building Regulations, air sealing is becoming a more prevalent aspect of the construction process. Reducing air movement in a building is a key aspect of controlling heat and subsequently energy usage, along with moisture control.
To quote the government’s current energy policy – air movement can account for 30% of more of a building’s heating and cooling costs. Flux can install preventative measures to mitigate and prevent this issue by sealing areas such as service voids, wall penetrations, window and door frames, cladding and the like.
