Typically, most manufacturers test cable conduits up to 16mm; however, we have tested details for up to 50mm conduits.
We have a detail where it can go directly through a single-skin plasterboard wall, and have also tested it in conjunction with our QuelStop Fire Batt.
One of the details seen in the video is a pattress-fitted fire batt with our QuelStop HPE Sealant around the outside of a conduit.
