Thorfun Posted March 8, 2022 Share Posted March 8, 2022 hello, I'm wondering how others with timber frame houses have fixed service cavity battens to the studs in the corners when you have internal PIR? we have 80mm internal PIR covered with an AVCL so in the corners it's not possible to straight fix to the timber studs so do you simply screw at an angle and hope that you hit the stud? e.g. or is just attaching at bottom and top plate enough?

cwr Posted March 8, 2022 Share Posted March 8, 2022 You could attach more batten to the side of the existing batten. Link to comment Share on other sites More sharing options...
Thorfun Posted March 8, 2022 Author Share Posted March 8, 2022 3 minutes ago, cwr said: You could attach more batten to the side of the existing batten. too late for that I'm afraid! the walls are already full of mineral wool and the PIR is already attached to the studs (and in one room the VCL is already fixed). if there's no other option then I can potentially do that but it's a ball ache. 😉 Link to comment Share on other sites More sharing options...
Thorfun Posted March 8, 2022 Author Share Posted March 8, 2022 4 minutes ago, cwr said: You could attach more batten to the side of the existing batten. and I presume you mean 'studs'? so add extra studs to the TF walls making them 80mm wider so it is past the PIR? that's a LOT of extra timber. plus a lot less insulation in between the studs.

Temp Posted March 8, 2022 Share Posted March 8, 2022 So essentially you are trying to screw diagonally through a batten into the corner of the stud. If you use some really sharp screws that screwfix sell that shouldn't be a problem. Can be hard predrilling the batten on the diagonal. Id either bash the corner with a hammer to make a flat point for the drill or i suppose run them through the table saw to cut a corner off. Then your drill starts easily on the flat surface. 1 Link to comment Share on other sites More sharing options...
Russell griffiths Posted March 8, 2022 Share Posted March 8, 2022 Sort of like your first thoughts. But I would get two battens and screw them together to make a corner piece, then offer this up into the corner and screw through on an angle. 2 Link to comment Share on other sites More sharing options...
Thorfun Posted March 8, 2022 Author Share Posted March 8, 2022 thanks guys. I like both those ideas. think I might amalgamate the two and see how I get on! I'll need to use maths to figure out the length of screws needed for that diagonal though. it's a good job we have Google! Link to comment Share on other sites More sharing options...
Mr Punter Posted March 8, 2022 Share Posted March 8, 2022 Another vote for pre-making the corners and fixing at an angle. 200mm screws will give the correct fixing, with 50mm embedment into the studs. Again, pre-drill everything. 1 Link to comment Share on other sites More sharing options...
Thorfun Posted March 8, 2022 Author Share Posted March 8, 2022 so, basically, this? 1 Link to comment Share on other sites More sharing options...
Mr Punter Posted March 8, 2022 Share Posted March 8, 2022 Will be OK. Make sure to plasterboard the shorter side first. 1 1 Link to comment Share on other sites More sharing options...
Thorfun Posted March 8, 2022 Author Share Posted March 8, 2022 thanks guys. I can fix to bottom and top studs in the wall so any diagonal fixing will be few and far between Link to comment Share on other sites More sharing options...
Thorfun Posted March 8, 2022 Author Share Posted March 8, 2022 thought of another question (although not specifically to do with the corner battens!). what is an acceptable distance between the fixings for the battens? 600mm? 800mm? or in true cowboy fashion 'that looks about right'?

Thorfun Posted March 8, 2022 Author Share Posted March 8, 2022 @ProDave how do you know how far apart to put the openings on the top batten? in your image below from another thread there doesn't seem to be any sort of standard? did you already know where sockets were going and so left top gaps accordingly or is it simply experience?

I left a small gap into each compartment. All around the room above is a removable strip of floor boards. In theory it allows for provision of extra cabling, e.g. thinking ahead to when hdmi is old hat and something else has replaced it. Link to comment Share on other sites More sharing options...

I'm sure it doesn't matter but my brain likes to know the details of what I'm doing despite winging most of the bits I've done so far! although it has been educated winging it.
