Just found these when looking for S shape telescopic "airbrick vents" the main purpose is for flood defence but Im thinking of using for something different
Quite a simple solution if your vents are to low to ground level (which after a previous owners block paving job - they are actually 9/10th covered)
Anybody had any experience with them - look a doodle to fit in comparison to fitting the telescopic vents if you can put up with the look of them on the exterior (can be painted)
