Porch doors and big gaps: choosing a deep draught excluder
Why porches are draughty
A porch door often faces the weather and sits over a rough threshold. The gap can be wide and uneven.
Depth beats width
For a big gap, choose depth first. A 10cm-deep excluder will fill the space better than a long thin tube.
A longer-term answer
If your gap is more than 10cm, the door probably needs rehanging or a bottom threshold fitted. An excluder is a good winter fix while you decide.
