Should I seal this plastic strip to stop draught?

[Mutley56]

Hello all,

I had replacement UPVc windows installed. Inside the bathroom window, there is a strip at the bottom of the frame separating the frame from the edge of the tiled window ledge. A draught comes through the top of this plastic strip. I telephoned the window installer and was told that this allows air to circulate to reduce consdensation. I thought that trickle vents served that purpose and I did not have these put in the frame as I have an automatic electric fan installed to remove steam.

I have uploaded a picture of the strip. My question is, is the installer right to say the draught is normal or should I run a bead of window frame sealant along the top of the strip to block out the draught?

Many thanks for your time and good advice.

Lets see a picture first but i would imagine the fitter is telling porkies, i've never seen a vent at the bottom of a window

Thanks for the replies, its the thin strip at the bottom of the frame where the tiled window ledge meets the plastic. The strip is about 5mm tall and the draught comes out from the top. As you say, its not a trickle vent but probably a filler of some sort. I'll seal the top of it to reduces the draught.

Thanks again.

Sounds and looks to me like its the back edge of the cill. If the installer hasn't put a bead of silicon on the back edge before fitting the window then you will get a bit of a draught coming under the window.

My installer didn't put any silicone on the back of mine but they are a reasonably tight fit. He deliberately didn't seal them (with my permission) as we had a pig of a job fitting the windows and they were in and out quite a few times.

Have a look at the level of the bottom of the window and see if it corresponds with the height of the back of the cill less a few mm.

Your fitter's a muppet. Run a thin bead of silicon along it.

Thanks guys, I've run a bead of sealant along the top to do the job.
