When installing our duct sealing system MDII, you will protect valuables from damage which is caused by gas and water leaks. The high quality, one component, flexible sealant “MD+” is based on a silicon compound that cures with air (Humidity).

During the expansion the polyurethane filling material penetrates all areas inside the duct, thus sealing all openings regardless of the shape of the duct or borehole. Roxtec offer a complete sealing solution for use across a huge range of industries both on land and at sea. 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. PU can be used in walls, roofs, ceilings, floors and more to provide insulation and structural support. Are you not convinced yet to use our MD5 Duct Sealing system instead of DIY Expanding PU foam from a can?Filoform duct seals type MD are based on a specially formulated two-component expanding polyurethane resin. Subscribe now to our POWER NEWSLETTER–packed with news, projects, videos, technical tips, training information, promotions, webinars, career opportunities and white papers. It’s a trial of our planning, building and provisioning processes and we’re learning a lot along the way. Tested under severe condition, suitable for wide ranging industries and for use in the harshest environments.

The Filoform duct sealing system FiloSeal+HD uses our MD+ sealant which is easily applied from a standard skeleton gun.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. 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. FiloSeal+ is suitable for sealing several cables or pipes contained in one duct and also allows re-entry of the seal to add or remove cables or pipes as required. 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.

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. Penetration Seals) – the integrity and insulation protection provided by the fire rated duct sealant will ensure up to 4 hours fire resistance in ducts. MD5’s specially formulated two-component resin is part of the same chemical/product family of similar electrical and construction industry products.In this BLOG, we'll cover the reasons why expanding foam fails when sealing cable ducts and what you can do about it. Other building services such as walls, ceilings and other characteristics can restrict access to the ductwork system making manual sealing difficult.

MD5’s resin can cope with small amounts of moisture in the duct or on the cables, but larger amounts of water will reduce the effectiveness. The Filoform duct sealing system FiloSeal+ uses our MD+ sealant which is easily applied from a standard skeleton gun.Should any un-mixed material spill onto a surface, a solvent wipe can be used to help clean the area. You won't find a single manufacturer of expanding foams in a can with the same test data for sealing cables in a duct. Air duct manufacturers can prove that they meet the tightness requirements of DIN EN 1507 or DIN EN 12237 through their operational quality assurance and through the use of high-quality manufacturing products in production, no longer have to deal with defects caused by the installation process.
