Trickle vent - frame, sash or overhead?

[SJRSJR]

Hello, any reason why manufacturers are doing trickle vents differently?

I've had four quotes for double glazing, two have the vents in the the sash and two have the vents in the frame. Currently my windows have the vent in a rail above the frame and it's quite discreet but no one has made that suggestion.

I've looked online and Duraflex do them (Duraflex overhead trickle vent) but from what I've read here, that profile is to be avoided. Liniar have also said they're doing one (Liniar announcement) but the supplier told me the vent has to be in the frame.

Is there a reason why suppliers make them differently and is any one way better than another? Thanks.

Im not sure what the difference between these

maybe you mean your windows have a joining piece on top of your window and the trickle vent is in that?
If so its probably because your window was manufactured to a design pre trickle vents and they added that as a way to avoid altering their manufacturing process

I dont see much isue with have a trickle vent in the frame -just be aware that they do end up very close to the plaster line

Yes, they're currently per the Duraflex design, from the outside the vent faces downwards. Not as obvious as having them facing outwards.

There will be some plastering to do afterwards, I'm guessing I can unscrew them to make it easier for the plasterer.

Thanks
