CSD Rise Multi Cable & Pipe Sealing System - Features :
Simple and effective : RISE Duct Seals are a multi-cable and pipe transit sealing system providing an effective and simple solution to all fire, gas and water tight duct sealing requirements.
Few Components : RISE Duct Seals system consist of only two components - 1) rubber insert sleeves used to guarantee cable separation and as a backing for the sealant layer, 2) FIWA sealant, a high quality silicone based, fire resistant, water repellent sealant which makes the duct seal system quick and easy to install.
Water and Gas Tight : RISE Duct Seals provide high elasticity and bonding strength which resists movement, shock and vibration providing a stable duct seal. RISE rubber insert sleeves are applied to provide cable separation and a backing for the application of the FIWA sealant. 60mm RISE sleeves are adequate for water and gas tight duct sealing.
Fire, Water and Gas Tight : RISE Duct Seals using rubber insert sleeves at a length of 160mm and applying FIWA sealant to both faces of the opening will provide a fire tight duct seal.
Flexible and Versatile : RISE Duct Seals can be used in vertical and horizontal ducts. RISE rubber insert sleeves cling to the cables without sliding down and falling out of the penetration. The high adhesion and viscosity of the duct sealant means it will not run or drip when applied overhead.
Adding and Removing Cables : RISE Duct Seals allow the installing of additional cables - it is a simple matter of coring into the soft rubber of the sealant to a depth of 20mm and passing the additional cables through the opening created. The duct sealant is then applied around the new cable to re-seal - there is no need to disassemble the transit system.
Cablofil EZ Path provides a complete a certified fire protection seal for cables and pipe entries or penetrations through fire rated walls and floors - Cablofil EZ Path maintains high performance wall and floor fire barrier.
Cablofil EZ Path offers fire protection (240 minutes) for fire rated floor and wall constructions in accordance with BS476 : Part 20 and European Standard EN1366-3.
Cablofil EZ Path - Intumescent Fire Barrier for Cables
Intumescent products expand with heat creating a fire barrier filling any gaps created as combustible through penetrations (ducts, service entries, floor and wall openings) burn away, which otherwise would leave an opening for the passage of toxic smoke, heated gasses and fire. Cablofil EZ Path provides airtight barriers for toxic smoke and gas ensuring personal safety during a fire. Where cables enter a fire barrer wall or floor Cablofil EZ Path firestop materials can be installed to restore an hourly fire-rating.
Two intumescent fire protection pads cushion and compress the cables top and bottom and prevent smoke propagation through the opening even if the intumescent material does not expand (Cold Smoke). Exposed to fire or high temperatures, the intumescent fire barrier responds to flames or heat by rapidly sealing the cable pathway, duct or service entry and preventing passage of flames and smoke. Cablofil EZ Path ensures maximum fire protection and resistance whether it is empty or full - therefore EZ Path provides excellent fire protection with every new or retrofit cable installation.
Built in Future Use - Cablofil EZ Path features a built-in firestopping system that automatically adjusts to the number of cables running through - cables can be added or changed without the need to remove and re-install fire stopping materials.
Cable Tray -cables present in cable tray can provide a source of fuel to propagate fire, release toxic smoke and gases. They create openings that can compromise the fire barrier allowing spread of fire, toxic smoke and superheated gases.
