As a result, achieving leakage rates outlined in BESA DW144 and an air tightness class C or D for an already installed air duct system was usually not possible.

CSD produced an innovative and cost effective solution to seal our over populated broadband cable ducts.

The unique design of the tri-flexible foam makes positioning and separation of the cables very simple while also providing a backing for the MD+ to be applied on. Duct sealing system FiloSeal+HD is an engineered universal solution for sealing LV-HV cables and pipes in ducts, boreholes or transit frames. If not, you should never use DIY expanding foam like what's shown in the image below because it is messy and can create more problems than it solves. 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. It is essential when installing the RISE and NOFIRNO duct seal systems that the ducts or building entries are dry and that the water pressure does not build up behind the seal which could cause failure during the curing of the sealant layer.Penetration Seals) – the integrity and insulation protection provided by the fire rated duct sealant will ensure up to 4 hours fire resistance in ducts. 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. However, duct sealing is usually one of the last stages of a major project so I perhaps understand why a poor choice is made to go with DIY expanding foam.

Comfort issues can be linked to poor temperature control from inefficient HVAC, these systems can have their efficiencies boosted by improved airtightness.We'll start with some information about polyurethane DIY foam comparing to our MD5 Duct sealing Resin. We'll eagerly provide all the information and assistance necessary to ensure that your needs are met on time and hopefully within budget. The expanding foam is an ok product for sealing small gaps, filling voids and cracks, and insulating.

The high quality, one component, flexible sealant “MD+” is based on a silicon compound that cures with air (Humidity).

The installation crew were skilled, hard-working and resourceful and also integrated well with our own men who supported then with the external duct sealing. The Filoform duct sealing system FiloSeal+ uses our MD+ sealant which is easily applied from a standard skeleton gun. All CSD products have beenextensively tested, not only atBeele Engineering technical laboratoriesin the Netherlands, but also by independent experts.

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. Aeroseal helps companies meeting the environmental commitments by reducing power consumption and therefore carbon footprint. The system is used extensively across the utilities and construction sectors to protect electrical substations, equipment rooms and cabinets, wind turbines and critical infrastructure. Ductwork leakage rates are outlined in BESA DW144 and systems should be manufactured and installed to comply with this specification.It’s a trial of our planning, building and provisioning processes and we’re learning a lot along the way. If there is room and the cables are de-energized, a power tool to speed the process up could be used. Tested under severe condition, suitable for wide ranging industries and for use in the harshest environments. Duct sealing solutions should be engineered into the job and training completed in advance of the fieldwork. Duct sealing system FiloSeal+ is a universal solution for sealing cables and pipes in ducts or bore holes.
