Mount TV on insulated stud wall

    Hi guys, wondering if anybody has encountered this before. I would like to mount my TV on a stud wall. Happy enough with mounting the bracket to the studs etc. but where it gets tricky is that the wall is filled with foam insulation so cable concealment is gonna be a pain. Want to avoid external cables if I can and not a fan of trunking either

    Has anybody ever used something like these to fish wires through foam insulation? Seems possible but a real pain I bet

    Also there isn't a socket where the bracket will be unfortunately (or directly underneath), just 2 metres below and to the left so can't simply run a cable up from that to install a new socket. Considering using an extension lead instead but in an ideal world i'd install a socket which would then be covered by the bracket

    Scratching my head a bit on this one so would appreciate any help

    Thanks!

    I agree with you, surface mounted cables look awful! They can ruin the look of a room.

    Anyway I spent many years working as an electrician, during this time I became particularly good at routing cables through stud walls. My secret weapon became the lid from 12mm min trunking. This would keep straight within a cavity, can be bent to shape, can go around corners when required, is readily available and very, very cheap. Due to the super low price (less than €4 for 3m) you don't care if you have to sacrifice it.

    you wont be able to fish it through the foam.
    In addition you may damage the A/T layer, especially in a TF house

    Its a bit more work but what I have done for clients with this requirement is just add on a new service slabbed/ skimmed and painted cavity outside the existing: works best in alcoves or where you have two changes of direction

    Yeah I'd be inclined to agree re: fishing through the foam. This chap makes it look very simple but I have my doubts

    It depends on the foam type, how dense it is, how tightly packed it is, how far the cables are being fished etc. sometimes it is impossible, other times not.

    True. Suppose I could give it a go and see how I get on. Worst case scenario I fill up the holes, paint them and pretend it never happened :o

    I've done a couple of installs (4) here in my home all seamless: https://www.fordownersclub.com/forums/topic/80864-living-room-project/

    I've also used those rods for fishing but I've found some coaxial sattelite cable to be more manoeuvrable
    You could use a Stanley knife to cut out the plaster and fit a flexible PVC drain pipe hose inside followed by filling with Ronseal ready mixed filler then sanding smooth, the Ronseal filler is very workable.

    If theres a block wall behind the plasterboard then I recommend using rigfix fixings for the bracket
    If it's just plasterboard then I recommend GripIt fixtures
    Fit a C13 power cable you can then convert it to figure 8 using a plug adapter; sort of future proofs your installation,
    Some televisions take a sattelite feed aswell as a terrestrial now too,
    So if you have some coaxial I'd run two feeds.
