HOWDENS DTFGLE01 Door to Frame Gap Instructions
Required door to frame gap once installed
Approximate door to frame gap before any further works
⚠ Howdens trenched fire doors linings are designed to give a narrow door to frame gap (typically 1.5mm), than what would be needed after installation. This provides the installer with the opportunity to trim the door to achieve the required 2 – 4mm gap. This avoids any possibility of the gap ever being too big and limits the opportunity to install non-compliant fire door sets.
On larger jobs involving multiple fire doors, when the installer would prefer not to have to trim the doors, we offer the option of an unwrenched fire door casing.
