Do they conform to building regs, my builder says they are not right?
Hello,
Thank you for your enquiry.
On their own your builder is right. However, if they are used in conjunction with intumescent protection, (which we do not currently sell) they can be used with fire doors.
Hope that helps.
Thank you for using Q&A.
