Door to Frame Clearances

The majority of architectural hinges are designed to be rebated flush into the door and frame. The gap when the hinge is closed to the parallel leaf position should therefore match the recommended clearance between door and frame. On steel doorsets this is usually set by the manufacturer. On timber doorsets the following guidelines can be used:

3mm for doors fitted with a combined intumescent and smoke seal. 2.5 - 3mm for doors fitted with intumescent only.

For doors which are not fire doors the recommendation is for a consistent clearance between door and frame within the range of 1.5 to 3mm
