Found the right stuff in Adelaide
Many thanks to all above for your information!
I called Alspec here in Adelaide (Torrensville ph 8150 6960) who couldn't supply residential quantities. They put me in touch with a company called M & S Glass & Glazing in Magill (ph 8361 3188).
I took the window to them and was given enough mohair strip for two windows to try before ordering and paying for all the windows.
Turned out that because the windows were so old, early '70s, the size to fit was the same as the modern door size. So I'll get more on Monday.
I spent way too much on heating last quarter, so minimizing the drafts will save a lot.
Thanks again & cheers! :)
A way to use readily available seals
The Brush Seals by Ravenand Moroday which are sold at Bunnings, Stratco etc. can beused in Aluminium doors and windows if the channel is 7mm wide.. Sprinkle TALCUM POWDER over the adhesive and in the channel. Theseal will then slide in easily .
Brush/mohair seal for aluminium windows
So happy to find this thread. I was searching for a solution for my drafty 70's aluminium windows - I checked, and on the closing side the mohair seal is completely gone!!! So, before I decide if I can do the job myself, I would like to know how easy it is to "thread" the new seal into the window frame on all 4 sides- is it possible to do without unsrewing the entire frame?
