Framefit is a unique retrofit product that reduces gaps in poorly fitted fire doors. Until now, if you have gaps of more than 4mm on either side or head between the door edge and door frame or more than 8mm between door bottom and floor, a new door costing between £600 to £1000 is the only way to make the door compliant with UK fire regulations. Framefit fire door gap filler makes the door frame fit the door by reducing the gaps to a compliant level. This will save spending hundreds, if not thousands of pounds while helping the environment because the existing fire door can be rejuvenated and not just thrown away.
