I need a way to calculate the amount of firestop wrap strip (CP648-E w45/1-3/4") needed for a project. Then the cost per case and how much a case contains.
Hello,
Thank you for reaching out to the Hilti Fire Protection Design Team to assist you with your firestop engineering needs.
At this time we do not have a tool to calculate the amount of wrap strip that one firestopping condition may require. In the past when asked about this, I have recommended calculating the circumference of the pipe using the outer diameter (rather than the nominal diameter) to determine the first layer requirement, and with each successive layer, add 3/8" to the previous diameter and sum the results. Wrap strips typically come in 10 meter (approximately 30 feet) spools.
