Gardner Bender DS-130 Duct Seal Compound, 1 lb. Pug, No Size, Grey

Product Information

Using a hammer & chisel or similar tool to break the seal around the cable and the inside of the duct 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. CSD RISE cable duct seals are specified throughout the electric and water utility networks to provide protection of ducts and duct openings against the dangers of water ingress and gas migration with up to 4 hour fire resistance to the spread of flame where cables penetrate fire rated boundaries and building openings – the watertight, gastight and fire resistant seals provide duct protection with accelerated age tests concluding a 50 year level of protection. duct sealing using csd rise seals

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. Poor performing HVAC systems can lead to poor indoor air quality (IAQ) and a reduced level of comfort in buildings. People can spend as much of 90% of their time in indoor space, and increased comfort and IAQ have proven benefits to productivity and reduced absenteeism. After injecting, the polyurethane sealant will expand and cures/hardens with a high density and a closed cell structure CSD Duct Seals provided extensive trials in the York and Aylesbury area using their simple yet effective product, RISE Duct Seal using a split pvc duct frame to create more space in the existing overpopulated cable ducts within the cabinets.Duct sealing system FiloSeal+HD is an engineered universal solution for sealing LV-HV cables and pipes in ducts, boreholes or transit frames. Flexible – the sealing system can be employed to seal circular, round or rectangular ducts or building penetrations Re-enterable – CSD duct seals enable simple modification for adding, removing or replacing cables in retrofit projects Selection should be at the design stage, where the seal requirements can be matched to the overall project. Typically, a design specification will require water, gas and perhaps fire resistance together with specific chemical resistance. The life of the seal needed should also be considered. Every seal manufacturer should be able to provide proof of expected life. Over-engineering the seal design should also be avoided. A duct sealing solution that meets the specific needs of the application is the right solution.

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!

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. Filoform duct sealing systems have been developed to provide an effective gas and watertight seal of underground cable penetrations. When installing our duct sealing system MDII, you will protect valuables from damage which is caused by gas and water leaks. 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.
