Guest AlanGl Posted January 30, 2013 Report Posted January 30, 2013 If a lock is changed and the new one is smaller than the old one is it posible to infill the door. if so what do the regs say, ive had a look on line but cant find anything. Many thanks Alan Quote
Tom Sutton Posted January 31, 2013 Report Posted January 31, 2013 I cannot see why not there is plenty of intumescent materials available to infill, like paste which would appear to be ideal. Contact one of the companies that specialise in intumescent products. Quote
