Guest Barry Posted November 3, 2015 Report Posted November 3, 2015 Hi We are a small modular building manufacturer in Yorkshire. We are currently struggling to find reliable information regarding when cold smoke seals are required in addition to intumescent strips. Would you be an organisation that could help us with this? Kind Regards Barry Quote
AnthonyB Posted November 3, 2015 Report Posted November 3, 2015 I don't know why, It's quite clear in Building Regs and all the guidance. A guick summary is if used to protect means of escape then the door should have smoke seals (e,g, be an FD30S or FD60S), if it's only to enclose an area of high risk or similar that isn't part or an escape route they don't (FD30 or FD60). A full list of types for situations is in Appendix A of Approved Document B Quote
