I am trying to source a suitable firestop product to fill a gap around a 100 diam conduit through a floor penetration (which has an irregular shape. It must satisfy a FRL or 240/240/240. Do you have anything to satisfy this need?
Hi Peter,
Thanks for contacting Hilti.
With the information provided, considering the conduit is PVC in this scenario, the CFS CP collar could be a good option. Please have a look at the table 14 of the RIR 27006 >> here.
However, for a more precise solution, we need additional details: slab thickness and type of conduit. Also, this application might require an engineering judgement (EJ) as the opening is irregular in shape.
Please reach out to our technical support team for further information >> here.
For more information about Engineering Judgements, please read this article >> here.
I hope the above is helpful.
Kind regards,
