Discoeye Posted May 1, 2023 Share Posted May 1, 2023 Good afternoon all. I'm going to be using FM330 foam as an intermediate around my Upvc windows and leaning towards finishing with Compriband TP600 on the exterior edge but depending on overall cost I might use an lmn silicone. So my question is are any Lmn silicones compatible over the FM330 or if any at all being they could react with the foam. Thanks all Link to comment Share on other sites More sharing options...
jayc89 Posted May 1, 2023 Share Posted May 1, 2023 One of my window openings isn't square so I don't have the gap to use TP600 on it. I plan on doing exactly this for that window. 1 Link to comment Share on other sites More sharing options...
Discoeye Posted May 1, 2023 Author Share Posted May 1, 2023 Funny, one of my windows isn't square either. So am I safe to say the silicone won't react with the foam. Thanks Link to comment Share on other sites More sharing options...
Redbeard Posted May 1, 2023 Share Posted May 1, 2023 I'd contact Illbruck. I did so recently to confirm that FM330 is still a/t when trimmed back (it is) and they were v helpful. 1 Link to comment Share on other sites More sharing options...

Discoeye Posted May 3, 2023 Author Share Posted May 3, 2023 Spoke to illbruck today they were very helpful and confirmed all would be fine then cheekily recommended their own brand of silicone. 😇 Link to comment Share on other sites More sharing options...
