HR Fireproofing Sealing

CSD were contracted to supply and install the HR Conduit Sleeves and NOFIRNO firestopping system at the site. The project had a requirement to maintain a 60-minute fire integrity requirement for all cable and pipe entry penetrations passing through Cross Laminated Timber (CLT) panels used within the wall construction.

The selected solution for the CLT wall type was a HR-frame sealed with NOFIRNO firestopping systems.

Facility Fireproofing

There were various challenges when it came to designing and installing a solution suitable for sealing the pipe and cable penetrations through the CLT wall panels. The solution had to ensure that the 60-minute fire rating was maintained when the panels were penetrated by any service passing into each unit. During CSD’s installation onsite, we worked alongside the M&E contractors to ensure that completion of each unit could be signed off on time.

Outcome of using Penetration systems

The penetration seal design with HR-frames and with NOFIRNO penetration seal system achieved fire resistance of more than 60 minutes. All openings were successfully sealed by CSD’S installation team and the project handed over on target.

Nofirno Penetration System

The NOFIRNO cable and pipe penetration system comprises of only a few components.

A correctly fitting NOFIRNO cable sleeve is placed around each cable, any free space around any services is packed using NOFIRNO multi sleeves before completing the seal with a 20mm layer of NOFIRNO sealant at each end of the penetration.

To ensure the NOFIRNO Sealant adheres correctly, the areas where the sealant is to be applied should be clean and dry before application. Furthermore for example any pipes or cables, and any frames or the building structure.

The system will provide a fire rated, water and gastight seal and has been shown to provide protection for a period of at least 50 years.

HR Penetration fRAMES

CSD’s HR penetration frames are designed for use in composite or sandwich panels. They allow cable or pipes to penetrate the panel. CSD’s NOFIRNO Penetration Sealing System will ensure the fire integrity of the panel is maintained.

The HR frames are available in a range of circular and rectangular sizes. It can be easily adjusted to suit the thickness of the panel.

key Benefits of Penetration Systems

• Assured to prove no deterioration in performance for more than 50 years
• Provides flood protection and prevents water and gas ingress. The pressure rated up to 2.5 from the front and back of the seal
• Quick and easy to install
• Easy re-entry for adding, removing or replacing cables
