The best way of getting fast feedback is to find the right sub-forum, and post a specific question there. If you have photos and/or drawings (especially sections for something like you're discussing), that will usually help a lot. 1 Link to comment Share on other sites More sharing options...

I have a cavity (yes, i can push some polyfoam/similar in the cavity. Currently there is only a "cavity closer" placed to cover the gap. As the door is fitted to the external brick leaf and screed are is poured only to the internal block leaf there is NO strength over the ~80mm cavity. My concern here is the strenght of the flooring in that section if you stand on it... it would likely cave in after a short time / be a problem with the flooring finish Edited February 9, 2023 by AdamL Link to comment Share on other sites More sharing options...
MikeGrahamT21 Posted February 9, 2023 Share Posted February 9, 2023 Hi Adam, for over the cavity take a look at compacfoam at Green Building Store, in fact I think someone was selling some on here in the marketplace. 1 Link to comment Share on other sites More sharing options...

Looks like the right product, thank you. I suppose I would need a very strong mechanical fixing ... somehow!? Link to comment Share on other sites More sharing options...

I suppose I would need a very strong mechanical fixing ... somehow!? I got a sample of this stuff ages ago and it’s rather crazy, you can screw into it like timber. you should be able to fix it to the inner leaf, either with metal screw and washer, or you could use a shortish plastic external wall insulation fixing like these: https://www.toolstation.com/fischer-dipk-insulation-render-fixing/p42435?utm_source=googleshopping&utm_medium=feed&utm_campaign=googleshoppingfeed&mkwid=_dm&pcrid=&pkw=&pmt=&gclid=CjwKCAiA_6yfBhBNEiwAkmXy5wOfdWzUTcYgnzaAqhy3S3hBgsFY4-7cYfyyzzq_fauWaT1pXgvM9RoCTeQQAvD_BwE&gclsrc=aw.ds you may well need to look for a smaller pack size tho!! 😂 1 Link to comment Share on other sites More sharing options...

MikeGrahamT21 Posted February 15, 2023 Share Posted February 15, 2023 Ahh i get what you mean, i thought you were floating this over the top to get rid of both the gap and the thermal bridge from the internal blockwork. How about something a little bit like this: https://www.ebay.co.uk/itm/175408005770 1 Link to comment Share on other sites More sharing options...
AdamL Posted February 20, 2023 Author Share Posted February 20, 2023 I spend all weekend removing the Philips Hue light strips from the protective rubber (so that they fit in my new aluminium profile/diffuser) no more warranty for me... Top section above kitchen wall units done... I now need to learn how to solder to continue the next parts. 1 Link to comment Share on other sites More sharing options...
AdamL Posted February 20, 2023 Author Share Posted February 20, 2023 I had a go at routing / fitting worktop together. (all the underside of the front edge is routed out with an aluminium channel ready for the next lot of Philips Hue Light strips. Then making a cut out for sink / taps. Not plumbed in yet, only for the pics. I need to take the work top off a few more times yet for other stuff. 1 Link to comment Share on other sites More sharing options...
Radian Posted February 20, 2023 Share Posted February 20, 2023 33 minutes ago, AdamL said: I now need to learn how to solder to continue the next parts. The best tip (haha) I can offer is that you need to make use of the solder to transfer heat from the soldering iron tip to the parts being joined. Just having the tip in contact with the wire/ PCB trace will tend not to transfer sufficient heat. Melted solder is a hot fluid that will transfer the heat nicely. Think of it like that and you'll make better solder joints. 1 Link to comment Share on other sites More sharing options...
AdamL Posted February 20, 2023 Author Share Posted February 20, 2023 I've got an old strip to play with and try this on before I wreck the new ones! Thanks for the advice Link to comment Share on other sites More sharing options...
