We'll start with some information about polyurethane DIY foam comparing to our MD5 Duct sealing Resin. Power Cables – specified to seal high voltage and heavy armoured power cables in single, trefoil or Triplex arrangement 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.

Duct Seals WIMES | The Water Industry Mechanical and Electrical Specifications (WIMES) define the requirements for a wide range of mechanical and electrical equipment used in the UK water industry including cable duct seals. 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) The CSDDuct Seal trials were a resounding success, culminating with Openreach rolling this out nationwide within their update of cabinets. In addition CSD Duct Seals are also looking to provide training for all of Openreach installation personnel and are currently working together to provide another project solution.Typically duct seals should conform to BSEN1366 Part 3 (Fire Resistance Tests For Service Installations. Penetration Seals) – the integrity and insulation protection provided by the fire rated duct sealant will ensure up to 4 hours fire resistance in ducts. 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. All duct sealing systems chosen have their strengths and weaknesses bar one. DIY expanding foam is inexplicably popular as a duct sealing solution. This is despite the fact that any duct sealed with it looks like it has some sort of malignent growth coming from it.

If there is room and the cables are de-energized, a power tool to speed the process up could be used. Once the seal is broken from the cable, there may be a crust of resin still present on the cable; this is due to the excellent adhesion our resin has. The hardest part of removing this seal is the crust that forms when the resin soaks into the foam flange. SafetyTraining and preparation - First, read and follow the manufacturer's instructions. Like any other job a field mechanic performs, it requires knowledge and skill. Duct sealing solutions should be engineered into the job and training completed in advance of the fieldwork. After application and full curing the thixotropic MD+ forms a plastic elastomer mass with special qualities effectively sealing and bonding, while providing a high level of durability. Duct sealing system FiloSeal+HD is an engineered universal solution for sealing LV-HV cables and pipes in ducts, boreholes or transit frames.
