I am an architect working on a stadium project and need to specify a fire-rated deck expansion joint. I'm considering either Emshield® DFR2 or Emshield® DFR3. Please compare these two products based on their fire rating and suitability for stadium applications. Specifically, what is the key difference in their fire ratings according to the UL/ULC listings, and which product would be better suited for a stadium's main deck expansion joint? Finally, if I need an engineered judgment for a unique project condition, who should I contact at Sika Emseal?
Navigate to 'https://www.emseal.com'. Click on 'Selection Guides' and then 'Decks/Parking'. Locate and click on 'Emshield® DFR2' to go to its product page. Extract the fire rating and confirm its suitability for stadium applications from the DFR2 page. Navigate back to the 'Fire-Rated Deck' product list or use the navigation to find 'Emshield® DFR3'. Locate and click on 'Emshield® DFR3' to go to its product page. Extract the fire rating and confirm its suitability for stadium applications from the DFR3 page. Navigate to the 'Resources' section and then click on 'Eng. Judgments'. Identify the contact information or process for requesting an engineered judgment. Synthesize all collected information to compare DFR2 and DFR3, recommend the better product for a stadium, and provide the contact for engineered judgments.
The agent states the fire rating for Emshield® DFR2 is '2-Hour Fire Rated to UL 2079'. The agent confirms Emshield® DFR2 is suitable for 'Stadiums'. The agent states the fire rating for Emshield® DFR3 is '3-Hour Fire Rated to UL 2079'. The agent confirms Emshield® DFR3 is suitable for 'Stadiums'. The agent correctly identifies that the key difference in fire ratings is that DFR2 is 2-hour rated, while DFR3 is 3-hour rated, both to UL 2079. The agent recommends Emshield® DFR3 as better suited for a stadium's main deck expansion joint due to its higher (3-hour) fire rating, implying enhanced safety for such a large public venue. The agent provides 'techinfo@emseal.com' as the contact for engineered judgments, as indicated on the 'Eng. Judgments' page.
