Hello.Where i can find details for minimum spacing distances for metal pipes passing trough a drywall?thank you
Thank you for your question. You can find the spacing requirements within the ETA approval of the selected firestop product. You can locate this in the Document section then Approvals on your local website under the respective item.
Hello.I already checked ETA for CFS-S ACR and there are no details about minimum spacing between uninsulated metal pipes.Thank you
Thanks for the update if no values are listed then the historical default distance is 200mm however if you would like to email the application details i.e. pipe material, pipe diameter, if insulated, non insulated, number of pipes, fire rating and partition thickness we look into this further for you see. Please email you local tech department directly. If in GB only then it's GBTAS@hilti.com
