Fire Door Seals
The flipper can improve the sealing performance of the doorset assembly, however, both flipper and brush can still achieve the requirements of BS476 and EN1634.
Yes. However, where the door or frame exceeds the height of the seal, we would recommend that any joins are installed in the lower extremities of the doorset assembly.
Yes. Brush and flipper seals can be wiped clean, using a damp cloth with a mild detergent.
Yes, paint can bind the seal making the seal difficult to provide a smoke sealing function. Flipper seals if painted or stained with a high VOC solvent can soften the material, and can cause embrittlement, resulting in the seal delaminating away from the main body of the extrusion.
Intumescent door strip is available in black only. Flexible door strip is provided with a coloured polymeric covering.
The material will produce fumes like most polymeric compounds. See the material safety data sheet on the product page for further information and guidance.
Refer to the Material safety data sheet for further guidance. The only product which contains such fibres is the Pyroplex mineral fibre sheet, all other intumescent materials do not contain such articles in the formulation.
In some applications such a pipe sealing penetrations, the intumescent material can withstand 4 hours fire resistant.
The intumescent material will start to expand in volume when exposed to temperatures greater than 180°C.
The expanded volume varies depending upon the end use application of the product, with a minimum expansion volume of x18 original volume with a maximum expanded volume of x25 times.
The reactive element within the Pyroplex intumescent material is based upon a thermally expanded graphite. When exposed to elevated temperatures, greater that 180°C, the material will start to expand in volume and continue to expand exponentially with exposure to increase temperatures.
A good source of information on the specification of fire doors is available from www.asdma.com
Yes. Our products can be made available in other colours, subject to minimum requirements.
Yes, we have worked with the leading manufacturers of adhesives and have approved list various adhesives approved for use on our products, please contact us for approved adhesives systems and manufacturers.
Yes, the collar needs to be firmly fixed to the supporting construction, failure to securely fix can comprise the integrity of the fire resistance of the collar.
Fire compartmentation in buildings in the form of walls and floors is designed to protect the occupants in and around a building and fire and rescue service personnel from the spread of fire by containing it in the compartment of origin for a period. Compartmentation is a vital part of the fire safety design of a building and seeks to divide large spaces into smaller, more manageable ones should a fire occur. Fire compartmentation is also used in order to create a safe, protected means of escape for the building occupants.
Yes, all the Pyroplex pipe collars and penetration seals are covered by ETA and Declaration of Performance documents are available for download.
For wall applications, we would strongly recommend that the penetration is provided with a collar, either side of the penetration.
Can I install a collar externally, without compromising the performance of the intumescent material?
Yes, the collar can be installed in external environments and the intumescent material will not be compromised by external weathering environments.
When exposed to elevated temperatures the polymeric pipe materials will begin to soften and collapse depending upon the material type. During the softening phase of the pipe, the intumescent material will expand, generating pressure to effectively crush the remaining pipe material, prior to being fully consumed. The intumescent will form a thermal barrier by forming a hard-residual char, to restrict the passage of fire through the supporting construction.
Sealants and Foam
The cartridges and foil packs are recyclable – see symbol classifications on the cartridges. All packaging can be recycled in accordance with the local market requirements.
The Pyroplex CE marked intumescent acrylic can be used in similar types application, linear joints, however, the movement accommodation is greater and can be use for sealing around pipe and cable penetrations. Refer to the technical data sheet for further guidance and information.
We would recommend using our CE marked Pyroplex intumescent sealant for this application.
The maximum gap width is 40mm in floors and walls. Please refer to the tables provided in technical data sheet, which outlines the requirements in terms of fire resistance.
