With winter coming up I am trying to get some maintenance around the house done, as well as improving on some things.
The house I live in has single glazed aluminium type windows. I would like to replace the the rubber/pvc type sealing at the parts were the windows can be opened. The seals are worn and have shrunk over time and left quite a few gaps.
The thing is I have no clue what they are called and if I need to get the exact same type or if they are other types I can use which might be better or improved versions etc.
I tried to find it and thought that something called a backing seal looks like it.

One other thing I would like to run by you. I am trying to improve on moisture coming into the house during winter. One thing I have read about is to put a heavy duty polythene ground sheet like this one https://www.bunnings.co.nz/eurosteel-250um-x-2-x-50m-black-polythene_p00261943 under the house as a moisture barrier.
Is this a useful thing to do?
I am asking because I have a garage under the house, where the floor level is about 1 meter lower than other areas under house. There are no walls between the garage and the rest. The garage floor is concrete. The rest is is not. The suspended timber floors are insulated with underfloor insulation (just in case that matters).
Will ground sheet still work for me if I use everywhere under the house but the garage?
