Seals all known materials: PVC & PE sheeted cables, PILC cables, (HD)PE pipes, PE drink water conduits Using this approach, inaccessible points of leakage can be sealed. Large sections of ductwork up to 150m can be sealed at a time dependent on design. Large ductwork systems can be sealed by breaking them down in to small sections. After injecting, the polyurethane sealant will expand and cures/hardens with a high density and a closed cell structure Properties of Cured resin: Fairley dense structure however can be dug out with a blunt tool & Hammer with some degree of difficulty.(Please note there is between 10-15 cm (4-6”) of the expanding resin in each seal depending on the size of duct)

Now as an integral component in the installation of new ventilation systems, maximum air tightness requirements for duct work can be guaranteed as well as achieved. Duct sealing system FiloSeal+HD is an engineered universal solution for sealing LV-HV cables and pipes in ducts, boreholes or transit frames. Should any un-mixed material spill onto a surface, a solvent wipe can be used to help clean the area. Reentering & removal Duct sealing system FiloSeal+ is a universal solution for sealing cables and pipes in ducts or bore holes.Following discussions, CSD Duct Seals were brought on board after providing a bespoke solution not only to a technical issue within the green cabinets, but a dramatic cost effective solution to Openreach. Extremely cost-effective, heavy-duty tape tile is designed to provide a clear visual warning when uncovered All our duct sealing systems are specified and used by major Electrical, Gas, & Water Utility companies in the UK and Benelux countries.

Failure to correctly and effectively seal cable ducts can inflict catastrophic damage to LV-HV electrical distribution networks, substations and power supply. View below our complete ranges of Duct Sealing Products including cable transits to provide a watertight seal and defence against flood damage to low, medium and high voltage cable ducts with additional protection against harmful flammable gas migration and fire spread. It is critical to evaluate the specific duct sealing situation and identify the objectives of the seal. For Example: Duct sealing system FiloSeal+HD is an eginnered universal solution for sealing larger heavy cables and pipes in ducts, boreholes or transit frames.In the UK the DNO’s (Distribution Network Operator) hold a statutory requirement to prevent danger due to the influx of water, or any noxious or explosive liquid, hydrocarbon or gas from the surrounding ground into substations, street boxes and buildings. The electric utility will have an approved method and material to seal ducts in all new, altered or retro-fitted cable installations – this includes the sealing of cable ducts where the ducting enters the switch gear building. Trusted – WIMES (Waters Industry Mechanical & Electrical Specification) accepted for duct sealing in the water utility sector Comfort issues can be linked to poor temperature control from inefficient HVAC, these systems can have their efficiencies boosted by improved airtightness. Approved – ATEX compliantfor hazardous area cable duct sealing in potentially explosive atmospheres, Zone 1 & Zone 2 Tyco RDSS Rayflate inflatable duct seal consists of an inflatable bladder with a sealing strip which is fitted around the power cable in a duct and inflated to create a watertight seal and is very versatile, adapting to most configurations independent of duct ovality.

Ductwork flanged connections, slip joints, seams and fixings can all leak, making it almost impossible to find and seal all leakage points on a large installed system. Are you not convinced yet to use our MD5 Duct Sealing system instead of DIY Expanding PU foam from a can? If not, please read the test data below, performed by ourselves. You won't find a single manufacturer of expanding foams in a can with the same test data for sealing cables in a duct.Once the application is complete and set, Aeroseal sealant is able to withstand 2000Pa of pressure with an estimated lifetime of over 30 years (provided ductwork is not dismantled or cleaned with oxidising chemicals). Energy saving calculations can be carried out after application, but it has been possible to reduce fan speeds and is some cases, reduce fan size after Aeroseal, whilst still achieving the required air volumes. Using a hammer & chisel or similar tool to break the seal around the cable and the inside of the duct Some industries write into the their specifications that DIY expanding foam cannot be used and these industries should be applauded for taking a stance against the poor results you get with it. Industries I know of who have explicitly banned DIY foam are the water industry (the major water companies of the UK and their contractors and sub contractors) and the petrol filling station industry. The latter is a good call as DIY expanding foam has virtually no chemical resistance to anything and actually dissolves in petrol! The revolutionary and patented AEROSEAL process was developed in the 1990s at the University of Berkeley/California. This technology has now been successfully applied in more than 125,000 air duct systems, in residential and commercial buildings, all over the world.
