Can't help with the strip. Can help with googlage though. When searching for something with a lot of hits that you don't need / want, add a "-" Eg. "Edge -Samsung -U2" and you will eliminate hits with those words in.
you already have the summer ventilation strips fitted, you need to add the winter strips for now until then. Available all good corner shops
Following recommendations I went to RS components who sell all sizes of grommet strip apart from 4mm where there is a big gap in their stock. Biggest clear size wa 3.2mm so as I hadn't actually measured the glass and it was only £5 for 5m I risked it. Too small.
Don't worry I've got your solution. Got half a tin here I don't need. Just buy me a beer when i see you. Kind regards Matt
I was pretty sure it would be too small, nothing ventured... I do know now that I'll find something more easily than I thought. As a side note, i'd retreated into eBay and Amazon to buy pretty well everything. Sometimes it's been frustrating, requiring lots of prior homework and finding i've bought the wrong thing. Having wanted to acquire stuff locally, just using Internet to locate local companies, I haven,t had to go far for great advice, cheaper prices and a bit of fun in the process. Long live the real world, I shall try to cut those leeches eBay and Amazon out of purchasing from now on and get out more.
