During a fire the NOFIRNO coating forms a ceramic protective shield creating a thermal barrier it will also prevent moisture from escaping from the mineral wool board. We'll eagerly provide all the information and assistance necessary to ensure that your needs are met on time and hopefully within budget. 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).

Poor performing HVAC systems can lead to poor indoor air quality (IAQ) and a reduced level of comfort in buildings. This seal is easily installed in vertical scenarios while providing the added security of ensuring no loss of components down the duct.

As with all two-component resins safety precautions must be understood to handle and install these types of materials. These entries such as open cable ducts entering substations or buildings should be sealed with or without cables installed to prevent ingress of water and gas – a common reference point in the UK is Engineering Recommendation ENA-ER G17/3 Leakage Of Flammable Gases.

FiloSeal+ is very easy to apply regardless of the type of cable scenario in the cable ducts as it uses a uniquely shaped foam piece which positions neatly around the cables or pipes in the duct. Suitable for ducts with a diameter of 40mm up to 200mm and cables or pipes with a diameter up to 160mm.

It is vital, to make sure the duplex foam is wrapped around each cable, to create separation from each other and the inside of the duct. PU can be used in walls, roofs, ceilings, floors and more to provide insulation and structural support.It can often be very difficult to pinpoint areas of leakage, usually there are many points of small leakage which contribute to a much larger leakage total. It’s a trial of our planning, building and provisioning processes and we’re learning a lot along the way. CSD RISE duct seal kits comprise of 2 components, rubber insert sleeves and FIWA sealant, making the sealing system quick and easy to install. 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.

Duct sealing solutions should be engineered into the job and training completed in advance of the fieldwork. 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. The high quality, one component, flexible sealant “MD+” is based on a silicon compound that cures with air (Humidity). Combines fast and simple installation with effective sealing performance against gas and water ingress. In this highly complicated operation, Johnny McQuoid, SFBB programme director for BT Group highlighted the technical challenges of the roll-out.FiloSeal+ is a universal solution for sealing cables and pipes in ducts or bore holes and is suitable for sealing several cables or pipes contained in one duct and also allows re-entry of the seal to add/remove cables or pipes as required. 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. Aeroseal works by injecting a water soluble sealant aerosol into the ductwork system using heated compressed air, the aerosol is then transported to the points of leakage from the inside and attaches itself to the side of the hole and over a period of approx.

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. It might work to hold back water just long enough for the contractor who applied it to get off site and get paid. Closed cell foam rubber sheets can be sized to suit any sized cable or pipe passing through any sized opening. This technology has now been successfully applied in more than 125,000 air duct systems, in residential and commercial buildings, all over the world. The seals can be customised to suit fire rated sealing applications including substation ducts, partitions, walls, floors, and construction systems including MV-HV switch rooms and transformer grids.
