Posted by Helen Hussey24 days ago

We need to install a new 600mm dia steel pipe with 80mm insulation through a 1000mm dia hole in a com floor ( conc app 150mm thick)
We need to fire stop between the pipe and the floor slab to maintain the integrity of the 2 hr floor.

Thanks for your question unfortunately it is outside the criteria of our standard products. It might be possible to achieve a seal but I suspect this would be via an Engineering Judgement only. I can only suggest as the next step is for you to contact your local HILTI rep to collate the details for feasibility check with our firestop engrs.
