Is there a company that can provide kits for adding air vents in double glazing window frames (PVC). I need something that I can drill / cut and clip on to the frames to provide ventilation.

If you have a genuine question, raise a new thread of your own. Don’t hijack someone else’s, especially one that’s nearly 4 years old!

Harsh?
Done a few retrofits of trickle vents for customers with BAD condensation probs (dont ask) . Removing the glass is not always required as you can see where the top of the bead (int or ext) is and work to a line greater than 10mm above this. Ideally, the frame should be routed, but thats impossible in 99% of cases where the frame is fitted, so stitch drilling is the next best thing and then opening up with the flutes on the drill running laterally back along the drill line - this is optional as it won't be seen as its covered by the vents. ALWAYS keep the drill horizontal if your going through the frame completely, otherwise you'll end up with a mis-aligned channel (oooh matron) . Personally, I hate the things cos they harbour insects etc. and the advent of night vent facility on opening sashes was one of the finest inventions ever as it complies with Part L (2002) and does away with these ugly things.
