In most applications discussed on this website and passive fire protection installation in general penetration seals are important.  Irrespective of whether some one is using a DuraSystems product or system, the importance of sealing any gaps in fire resisting construction is vital to ensure the integrity of the system.  Such gaps are typically at service penetrations through walls, floors and ceilings and would also include gaps left for structural movement and gaps due to installation tolerances.

Every service passing through fire resistant building elements reacts in a different way in the event of a fire, so there is no single solution or product that will protect all services.  Recognizing this, DuraSystems provides the following range of effective solutions to seal gaps at service penetrations:    

DuraSTOP

DuraSTOP is an energy absorbing compound system used to form seals around penetrations through fire and blast resistant walls, floors and ceilings.  Performing equally well is concrete or masonry structures and DuraSystems proprietary systems. 

DuraSTOP retains its mechanical strength during a fire and will withstand vibration and expansion.  Its seal is water and gas tight and will withstand the thermal shock and erosive action of a hose stream of water in the event of a fire.

DuraSTOP’s energy absorbing heat sink properties appreciably delay the conduction of heat along cable trays, cables, conduit, pipes and other metal penetrations requiring sealing.  This product will also stop the passage of chlorine and toxic gases generated by a fire there by reducing the risks to people and property.

DuraSTOP has been extensively tested and is non combustible.  These tests include fire tests up to 4 hours of protection to ASTM E119.  DuraSTOP is the product of choice of penetrations.

PROMASEAL Pillows

PROMASEAL Pillows maintains the fire resistance of walls where openings services are located.  The pillows can provide permanent protection from the spread of fire; however they are ideally used in temporary opening requiring fire protection.  

The compressible fire stopping pillows are made from quality woven envelopes, encasing a fire resistant material.  Simple to install, reusable and maintenance free makes these the idea solution for your penetration requirements.

The PROMASEAL Pillows are available in three convenient sizes:

Large 330mm x 200mm x 45 mm

Small 300mm x 200mm x 20 mm

Sausage 330mm x 50mm x 20 mm

PROMASEAL

PROMASEAL is an intumescent sealant used to close gaps around mechanical and electrical services fire resistant floor and wall joints and partition joints. 

Intumescent sealants such as PROMASEAL have excellent adhesive properties for sealing of joints and penetration for up to 4 hours.  It bonds to dust-free masonry, concrete, calcium silicate boards, gypsum, metal and cable covering.  The product remains flexible after curing to accommodate thermal expansion.

PROMASEAL is available in standard 310mm cartridges.

PROMASEAL Unicollars

It has been shown that plastic pipe penetrating fire barriers present a potential for fire to pass from one side to the other when the plastic melts and burns away.  All building regulations specify that the fire rating of the separating building element must not be impaired by services that pass through them.  That is why the PROMASEAL Unicollar was developed.

The Unicollar is the latest generation of retrofit fire collars designed to protect plastic pipes penetrating fire rated elements of building construction.  The collar is designed to cut and snapped to the required length. The multiple length collar can be sized to fit most applications thus requiring only one product.  Each box is equivalent to 5 110mm OD collars.
