Fire Stopping, Acoustic & Air Sealing

Building regulations outline the need for buildings to be divided into compartments, and specify the level of fire performance the compartment walls and floors need to achieve in order to preserve both building structure and life through fire and smoke containment. In most buildings, mechanical and electrical services breach compartment walls and floors allowing potential failure of fire integrity and insulation to occur where gaps around services have not been adequately or correctly fire stopped.

The use of proprietary certified fire stopping systems, when correctly installed by Fire Stopping Companies in accordance with manufacturer’s test data, will contain a fire at its source and limit the risk of the destruction caused by the spread of fire and the release of toxic gases.

For over 30 years we developed a reputation as one of the most trusted fire stopping companies. Our technical team is ready to assist you.

Intumescent Coated Batts

Fire barriers are high density mineral fibre boards with a white endothermic, ablative coating. These are designed specifically to stop the spread of fire through service openings in fire rated walls and floors and can provide up to 240 minutes fire protection. In addition to providing a fire seal, these barriers can also provide high decibel acoustic performance depending on installation specifics.

Fire Compounds

Passive Fire Protective compound systems are manufactured from single gypsum based or cement mortar compounds, with thermal and acoustic properties providing a fire seal around service penetrations through walls and floors. Fire compound systems are particularly designed for use in areas where a loading of the penetration is applicable, such as service risers. Fire compounds are quick setting to provide a seal offering up to 240 minutes fire resistance.

Intumescent Mastic

Intumescent Mastic systems are water based acrylic intumescent or silicone based sealants. Adhering to most types of surface it can be used for all building & construction joints and is used to provide fire protection to gaps & movement joints. It also provides fire protection around service penetrations when used in conjunction with the Intumescent batts which when cured form a non-hardening seal. This prevents the passage of smoke, toxic gases and fire for up to 240 minutes of fire protection.

Air Sealing

Passive Fire Protection, Air tightness / air permeability is defined as the resistance of the building envelope to inward or outward air leakage. Air leakage is driven by pressure differentials between inside and outside a building caused by wind, stack effect and mechanical ventilation systems. Excessive air leakage can lead to increased energy consumption, increased drafts within the building and increased risks of condensation within the building fabric. Fire Shield uses a variety of insulation products which provide the required seal between the internal and external perimeters of the building.
