Tricke Vents - Installed into Window Rather than in Frame Above

SimonVOwen

Hello,


I have just had double glazed windows installed at my house.
They were meant to install a trickle vent in the bathroom as we have condensation issues, however they forgot to built it into the windows and installed without.
They are now retrospectively installing the trickle vent but apparently it is too hard to install into the frame above the window and are going to install into the actual window.
Does anyone have any additional information on if this would as I believe that this would compromise the energy efficiency more than if the trickle vent was incorporated when it was actually built?


Many Thanks,


Simon

If they are going to drill into the double glazing, then yes, the gas that is trapped there would escape and compromise the glazing.
If they are going to replace the whole glazing unit with a new one that has ventilation built in, then that wouldn't compromise it, if it was designed and built like that.

I wouldn't accept it as a solution at all.

Either replace the whole frame, or install a proper vent through the wall

Putting a trickle vent in the head of the window sash, that is in the plastic profile, is common. Mine are done like this, and it is preferable to having them in the frame - both for building reasons, and for reaching to them. If this is what you are having then make sure the outside vent is sealed to the sash profile.

I'm sure they don't mean in the glass itself, they'll mean the plastic frame of the opener. Which is fine and perfectly normal.
