Description

Duct Seal FR Cable Duct Sealing System: Fire Resistant Protection for Critical Installations

The Duct Seal FR Cable Duct Sealing System is an advanced, fire-resistant solution designed for sealing cable ducts and duct openings. It features a low-smoke, zero-halogen formula, making it ideal for applications where fire resistance and safety are paramount. The system effectively seals against harmful or flammable gases, liquids, fire, smoke, and pests, providing exceptional protection for AC cable solutions in harsh environments. It has been rigorously tested according to BS EN 1366-3:2021, meeting stringent fire certification requirements.

Fire Resistant materials: Up to 4 Hours of Certified Protection

The Duct Seal FR system provides fire resistance of up to 4 hours (240 mins), in compliance with BS EN 1366-3:2021. This fire certification ensures the product meets the highest standards for installations requiring fire resistance, including both horizontal penetrations and low-density concrete walls. It is suitable for a wide range of cable types, including NYY-O, N2XH-J, HO7V-K, and telecommunication bundles, making it a versatile choice for sealing multiple cables.

AC Cable Solutions: Reliable Sealing for Diverse Applications

Designed with AC cable solutions in mind, the Duct Seal FR system accommodates a variety of cable sizes and types, including heavy cables and bundled cables. It features a patented trefoil/triplex separation system, ensuring minimal cable movement during installation. The product's unique backing support system, featuring tubular rubber tubes, enhances structural integrity, providing robust sealing for AC cable installations.

Neutral Curing System: Safe, Non-Hazardous, and Efficient

Duct Seal FR utilises a neutral curing system, which includes a non-hazardous, zero-MEKO intumescent sealant. The superior single-component formula is designed for safety and ease of use, releasing no harmful gases during application. This neutral curing sealant effectively seals cable ducts and provides long-term protection in a variety of environments, including dry and wet conditions.

Features of the Duct Seal FR System

• Fire Resistant Materials: The entire system, including the intumescent sealant and sleeves, uses fire-resistant materials tested at Warrington Fire (Exova).

• Low Smoke, Zero Halogen: The product’s formulation is low smoke and zero halogen, ensuring safety in confined spaces and during fire exposure.

• Gas Tight and Water Tight Sealing: The duct sealing system effectively resists toxic and flammable gases, hydrocarbons, and water ingress, making it suitable for use in the petrol forecourt industry and other critical installations.

• Flexible Intumescent Adhesive: The system includes GreyStuff or RedStuff, a flexible intumescent adhesive that ensures a secure seal in complex applications, such as accommodating trefoil cables.

Applications: Where to Use Duct Seal FR

The Duct Seal FR system is designed for use in challenging environments where fire resistance and reliable sealing are essential. Typical applications include:

• Data Centres, Substations, and Pumping Stations

• Wind Farms, Waste to Energy Plants, and Electrical Utilities

• Petrol Station Forecourts and the Petrol Forecourt Industry

• Rail Projects and General Construction Sectors

Product Configurations and Kit Sizes

Robust Structural Integrity and Cable Suitability

The system features intumescent circular-shaped tubes that can be seamlessly connected or reconfigured into a cross-shaped structure for trefoil cables. This innovative design minimises cable movement during installation, providing strong structural support and ensuring that the sealing compound fully covers the duct opening. The system’s unique backing support, made from tubular rubber tubes, enhances the seal’s strength and durability.

Fire Tested and Certified: Approved for Critical Environments

Duct Seal FR has been fire tested and certified at Warrington Fire, meeting the approved tested configuration requirements. The product’s fire rating is validated for up to 4 hours of fire resistance, making it an ideal choice for applications requiring stringent fire certification.

Locally Manufactured for High Quality and Compliance

All components of the Duct Seal FR system are manufactured locally in the UK, ensuring consistent quality and compliance with local fire safety regulations. The product is designed to meet the demands of the market, offering a low-smoke, environmentally friendly solution that is backed by comprehensive fire certification.

Important Note on Installation

A fire rating is applicable only to an "as fire tested" system or an otherwise approved configuration. The entire system or configuration achieves the described fire rating only when a specific proprietary brand of product is installed in an identical manner to the approved tested configuration. Always ensure that your installation matches our fire test certification. It is the end user's responsibility to verify that DuctSeal FR is the correct system for the project requirements. Please contact our technical department to request a copy of our test report, and refer to our Duct Sealing Disclaimer.

Installation

One Kit per Box

All components included to seal 1 x duct as per the kit size mentioned (Caulking gun not
included, but can be sold separately).
** One kit may fill more than one duct, depending on cable % fill.**
Call +44 (0)161 874 1480 for advice.

Cable Separation

It's imperative to ensure separation between each cable and from the inside of the duct.
Our unique daisy-chained circular tubes easily separates and supports single or multiple cables. Using our patent pending tubular rubber tubes, various shapes can be made to help with cable separation, for example, trefoil/triplex cables

Running Water

The duct & cables can be damp but with no running water. All dirt, oil or grease must be
cleaned before applying GreyStuff or RedStuff.

Cure Time

GreyStuff and RedStuff will cure 3-4mm daily, depending on the Humidity and temperature. The higher the humidity % and temperature, the quicker our sealants will cure. A minimum requirement of 25mm is required for an effective seal.

Cleaning

Uncured material spillages can be cleaned with a solvent-based wipe.

Fire Certification

Important Note: A fire rating is applicable only to an "as fire tested" system or an otherwise approved configuration. The entire system or configuration achieves the described fire rating only when a specific proprietary brand of product is installed in an identical manner to the approved tested configuration. Always ensure that your installation matches our fire test certification. It is the end user's responsibility to verify that DuctSeal FR is the correct system for the project requirements. Please contact our technical department to request a copy of our test report, and refer to our Duct Sealing Disclaimer.

GreyStuff or RedStuff Fire Resistance

GreyStuff sealant was tested according to BSEN1366-3:2023. RedStuff has not been tested, but can be used with your authorisation only (customer and/or end user). We can confirm that the difference between GreyStuff and RedStuff is less than <1%. The only change in the formulation from GreyStuff to RedStuff is the pigment component. This alteration does not affect the fire resistance, physical properties, or manual handling of the final product.

Health & Safety

GreyStuff & RedStuff are based on a neutral curing system that is hazardous-free to protect users when carrying out tasks like sealing cable ducts. Non-hazardous Zero MEKO.

Re-entry & Removal

GreyStuff & RedStuff will cure to a similar hardness of a rubber eraser, so re-entry and
removal are achievable. The ease of this depends on the type of tools used. For example,
a sharper tool will be easier than a blunt-ended tool. Only use sharp tools when cables
are de-energised. AC Cable Solutions accepts no responsibility for damaged cables.

Cable Suitability

GreyStuff and RedStuff are a single-component neutral curing system containing no solvents. Our formulation does not damage the properties of a cable sheath, or stain surfaces.

Storage

Both GreyStuff & RedStuff should be kept in a cool, dry environment and away from
sunlight. Product shelf life is 12 months. Once opened, any remaining product can still be used for 1 month afterwards, provided the screwcap is securely fitted.
