when windy my windows make a whistle noise ?

the noise you hear usually comes from two problems first check silicone around window for loose flapping next check drainage holes when windows are made sometimes were routered pvc fragments not cleaned out this causes humming noise if this is the problem fit sponge in the drainage holes this will allow water to escape and reduce the air flow that causes the noise

Phil. Cutting through the previous BS - most modern windows have a strip locking system with cams and shootbolts. If your windows have cams that engage in keeps within the rebate, open the window and look at the gold lock strip and on each cam you will notice a small mark or line. This could be facing at any point on the compass. By inserting an allen key into it you can turn it through 180 degrees, and as it moves eccentrically around its centre, it will have the effect of tightening the sash into the frame when you close the window with the handle. If its too difficult to operate at 180 try less rotation and see if this works. Finally, in my years of fitting and snagging pvc I have found that it is not always the opener that can cause noise - check for pinholes or mis-seals in the silicone around the frame and reseal if necessary. Good Luck.

What you are noticing is what we smart arses call Acoustic Resonance which happens when a system's resonant or natural frequency is matched by externally imposed forces of oscillation at the same or similar frequency - many would just call this a whistle.

If you modify the airflow; by opening the window for instance, you change the frequency of the external force and the whistling stops.

You might also put a brick on the window sill, place a board or ladder against the wall, a trellis for plants - anything to alter the way the air passes across the face of your window. Wind Chimes would do it! A batten fixed vertically on the windward side of the brickwork - anything that takes your fancy.
