Good morning,
I'm looking for a 1,5h fire-rated protection for an already-installed electrical conduit in a nuclear site. Please, could you provide guidance and technical specifications of products that could be installed (such as a kind of wrapping or a fire-rated shaft).
Thank you in advance,
Hi Sara,
We would require more details to provide the solution or suggest any Firestop products. They have some parameters like Barrier type, type of wall/floor, opening size, electrical conduit material, Number of electrical conduits, etc.
For 1.5-hour F ratings in an electrical conduit case generally, concrete wall/floor we can suggest C-AJ-3095 which is with Hilti FS One Max intumescent sealant. We do not have a certificate with a particular 1.5-hour F-rating hence we are suggesting a 2-hour F-rating certificate. Further, this certificate does not cater to other attributes like movement capability in through penetration cases.
Note: Hilti products are designed for interior applications only. Our firestop sealant is not designed for exterior applications and has not been tested to the standards for exterior sealant/spray.
Please feel free to reach out to us for any further clarification.
Regards,
Team Ask Hilti SEA
