Peace of mind in fire security 

Retro fitting solid core doors

Some solid core doors can gain a fire rating by routing a channel around the top and sides and fitting an intumescent strip

Some solid core doors can gain a fire rating by routing a channel around the top and sides and fitting an intumescent strip (a minimum 20mm brush seal strip is to be used). All hardware must be of fire resistant construction and any damaged hinges replaced. If the door is leading onto an escape path then a vision panel may also need to be fitted. If they already have a vision panel fitted it may be necessary to upgrade the glazing beads to a hardwood bead, with intumescent strips placed behind, and screws crossing over into the body of the door.
