Ventilation

How can I improve ventilation in a room?
To improve ventilation, you can add a night vent fastener handle to your window, which can be locked in a slightly open position to create a small amount of air flow whilst providing security. For further ventilation, we recommend adding a trickle vent. This is usually fitted to the top of a window frame with the vent on the inside, a grill to prevent insects entering, and a canopy on the exterior to prevent rain.
