Hi - I live in a purpose-built block of flats (constructed in ~1970) and every flat needs to modify its flat front door so it can be considered to be a notional FD30S fire door assembly (existing door/frame with intumescent strips, intumescent letter box, fire-rated hinges and a door closer). The doors are suitable for modification (hardwood and 44m wide). I've installed 3 brass hinges (CE Reference = CE 4-7-6-1-1-4-0-13) and I'm trying to establish whether these need to have intumescent pads/liners underneath the hinges?
As I now have a door closer fitted, my door will always shut and the intumescent strips/letterbox (with brushes) will ensure my door will self-seal if a fire took hold. I'd like to establish (for a notional fire door) whether intumescent strips are discretionary (nice to have) or mandatory (must have) for 3 brass hinges (CE 4-7-6-1-1-4-0-13). There seems to be a lack of guidance on his topic and when I bought the hinges online (Tradefit) didn't come up with the product.
If you have any experience on this topic, I'd be grateful for your input. It's been a learning curve to get this far and it's a final point to clarify.
Many thanks
Conrad
