Identifying rubber gasket - integrated and how to replace

[jpydx]

Hi,

I have these rubber gaskets on all my windows and doors produced by Selecta Systems.

They don’t seem to be gaskets you can remove and pull out.

The edge of the gaskets seems to be glued to the frame and integrated.

When I cut into it, it looks like this.

Any ideas if this can be replaced and what it is?

Tried my best on the photos. But imagine a piece of rubber in a semi circle with each end glued to the frame.. that’s how it seems.

Happy to cut a full piece out if needed but don’t want to hack away at the windows when I can’t seem to find this kind of gasket on the internet anywhere!

Thank you

There is a slot behind to allow for a clip in gasket should you need one, what's wrong with the original co-extruded one though

Ah! Lovely stuff!

That’s a great diagram that’ll look at later in more detail but this makes sense.

It’s completely gone. I don’t know why. The windows on my lower floor let in such a draught. The road noise can be mistaken for having the window open at times. The gasket is quite flat in areas.Not sure why.

I’ve tighten the hinges previously for a better fit but it’s still leaky.

It’s gotten to a point that you have to wrap up if you sit by one of the windows during the colder months as the draught is ridiculous!
