Other than it smelling like a cheap Chinese air rifle what's the score with it? I'm thinking it might be worth sticking a temporary timber batten up between the joists to keep the pilot drill on centre.

Onoff Posted February 15, 2018 Author Share Posted February 15, 2018 Right then, the Silverline hole cutter IS perfectly usable IF you use something solid to keep the 8mm pilot true. In plasterboard, without it, imo you're on a hiding to nothing. I tried it without then screwed on a bit of scrap 9mm ply. The pilot wobbled so much in the pb to start with it was just ripping and tearing rather than cutting: So with the ply scrap: Happy with that. Wine o'clock! 1 Link to comment Share on other sites More sharing options...
Russell griffiths Posted February 15, 2018 Share Posted February 15, 2018 (edited) If you drill the centre hole you could probably insert that and turn it by hand if it’s just plasterboard you have to go through. You beat me to it. Well done ? Edited February 15, 2018 by Russell griffiths Link to comment Share on other sites More sharing options...

Construction Channel Posted February 15, 2018 Share Posted February 15, 2018 3 questions, - where is the hole in the VCL from the pilot hole? -is that a 3 speed makita drill? if so, you lucky bastard, someone stole mine and they are virtually impossible to replace. - how can you sleep at night with so few screws in your ceiling? 1 Link to comment Share on other sites More sharing options...

Very stubby drill on this Silverline thing, it pushed up and only just pierced the vcl. Yep, BHP451...I wish I'd bought a couple more tbh. The body dryer comes with some weird "material" straps. Not fitted yet so I added a few more screws. NO I didn't measure them! That was a horrible moment cutting the vcl, OMG the draught! In she goes temporarily: The timber box will be lined with Asbestolux or similar. The rest of the vcl under the dryer will go: A few more screws. A couple of 20mm holes for the control cable and the DRAIN! To fit, the cover. 4 screws but the positions aren't on the card template. I'll figure it tomorrow! 1 Link to comment Share on other sites More sharing options...
Onoff Posted February 15, 2018 Author Share Posted February 15, 2018 The cover fits to the ceiling with 4 curly wurlys! It doesn't actually screw through the pb and then to the black "fan" deck. So the fan deck just sits there atop the pb under it's own weight so to speak...which is weird. Must read instructions... Link to comment Share on other sites More sharing options...

Onoff Posted February 17, 2018 Author Share Posted February 17, 2018 I screwed up a bit here I SHOULD have cut the vcl BEFORE I drilled / cut the big holes! What I want to do is bring the vcl up the sides of the timber joists and over the top. I'm going to have or course to add some vcl and seal the joins. A fire resistant plasterboard "lid" will then be screwed down maybe on an intumescent bead. It's a nod to putting the integrity of the vcl back. Save me having to buy airtight tape, would Gorilla Tape be OK? It says you can fix paddling pools with it. Link to comment Share on other sites More sharing options...

I reckon though if I cut and bring the vcl that's there up and over the joist I could add more & set my Asbestolux boards on intumescent mastic. Where the boards meet the plasterboard and the 4 internal corners of the lining. Link to comment Share on other sites More sharing options...

Onoff Posted February 17, 2018 Author Share Posted February 17, 2018 Bugger! I remember when I laid the PIR that I took so long and walked on it so much that the foil started peeling off. Then the foam itself started laminating / disintegrating. I "saved" it by going mad with the foil tape. Removing the Polypipe panel now and I've made multiple slices into the repaired foil and the foam is literally falling apart even as I vacuum it! I reckon the best way to salvage this is to slip in some squares of heavy duty baking foil and again foil tape. Will the liquid DPM affect the Pex-Al-Pex pipe I wonder?

It shouldn't do, as it's safe to use in contact with polyethylene DPM, but if you want to be sure then you could test a sample. Link to comment Share on other sites More sharing options...

Jeremy Harris Posted February 17, 2018 Share Posted February 17, 2018 Is it really 9 kW? If so then it would really warm the bathroom up quickly, along with the rest of the house! Link to comment Share on other sites More sharing options...
