Intumescent Fire Sleeves
Intumescent fire sleeves are essential components within a system of fire stopping products, used to maintain the integrity of fire compartments when building services pass through walls and floors. Designed to swell under heat, these sleeves close openings left by combustible pipework that would otherwise allow fire and smoke to spread unchecked between compartments. They form part of the passive fire protection strategy, working automatically without the need for any external activation, and are tested as part of the complete sealing system around service penetrations to preserve the fire resistance of the construction element.

Intumescent Fire Sleeves for Passive Compartmentation and Service Penetration Sealing
Intumescent fire sleeves are a passive solution for sealing pipe and cable penetrations and play a critical role alongside door upgrade kits in maintaining fire compartmentation. Where fire doors control the spread through openings like corridors, fire sleeves protect smaller but equally vulnerable service penetrations - such as those created by plastic pipes - which can otherwise become a channel for rapid fire spread if left unsealed.
Fire sleeves expand under intense heat, forming a dense insulating char that blocks smoke, heat, and flames from breaching the fire-resisting construction. Their correct use ensures that walls and floors maintain their integrity and insulation ratings when services pass through them. These devices are crucial in preserving the fire-resisting properties of compartment boundaries and are tested under load-bearing and non-load-bearing conditions depending on the construction type. Since services vary across builds, installation must align with the original tested configuration to guarantee performance.
Only tested and approved sleeves - installed according to manufacturer specifications - can ensure compliance with Building Regulations. In practice, they form part of a layered defence strategy, particularly where fire-stopping solutions must account for the pipe material, wall construction, and desired fire resistance duration. Their use reduces the likelihood of unseen fire and smoke migration within building cavities and contributes to safer evacuation conditions.
Intumescent Fire Sleeves FAQs
Can fire sleeves be used with metal pipes or just plastic?
They are primarily designed for combustible pipework like plastic, but systems may also be used with metal services when part of a tested configuration.
Do fire sleeves replace the need for pipe collars or wraps?
No. The choice depends on pipe type, wall construction, and tested solutions. Collars, wraps, and sleeves are different tools in the fire stopping toolkit.
Are fire sleeves suitable for use in ceilings as well as walls?
Yes. They are commonly used in both horizontal and vertical applications to maintain the fire rating of compartment elements.
What fire rating can be achieved with a sleeve?
Depending on the tested configuration, fire sleeves can help maintain integrity and insulation for 30 to 120 minutes.
