ISP Duct Sealing Systems – Fire, Gas & Water Resistant
Underground cables and pipes entering buildings, can allow gas or water penetration if they are not sealed correctly. Gas which escapes can be particularly dangerous, causing explosions and fire where the damage can run into very high figures.
Rain and high ground water levels that flood into buildings through ducts, can cause extensive damage to equipment.
ISP / Filoform have developed an effective answer to these problems with their range of duct sealing products.
For decades, these products have been widely used by several network operators, gas / water and electricity distribution companies, telecom companies and building contractors in the UK and the rest of Europe because of their advantages:
- 100% Gas and Watertight
- Resistant to Hydrogen Sulphide /Methane and many other Gases
- Fire rating on all duct Sealing Products – in accordance with BS EN1366-3:2009
- ATEX Compliant
