Cooker hood fixings

[GTLC]

I'm about to fit my cooker hood, but I'm unsure of the type of fixings to use.
The wall is 12mm insulated plasterboard (with 30mm insulation) and on top of that I have 8mm MDF splashback fitted.
In not sure standard plasterboard plugs will work through all of that.
Any ideas?

Is there brick or blocks behind the plasterboard or is it a hollow wall

 

[GTLC]

It's hollow. Just a stud wall.

So presumably you can't get fixings into the studs. I would look at something like this

But check the instaltion instructions for weight and suitable siting

Thanks. I was hoping to avoid big holes in the splashback, in case I had to change the hood in the future, but think you're right. These look like the solution.

Decide where the hood will go, place it, draw round it, remove that much plasterboard with a multitool or jabsaw, replace the plasterboard with noggins and ply so you have something to easily fix the hood to

Sounds like a rather big hole to me!

Could you perhaps, drill alternative fixing holes, in the hood?

Mark on the wall, the outer profile of th hood, where you need to locate it. Next, you need to work out just where the timber battens are located, behind the plasterboard. The PB will be fixed to the battens, with screws, so a strong magnet, run around the area, or a metal detector, should help you find, and mark them. Now, see if you can drill holes in the hood, to screw it to the battens.

If you cannot do that, mark the wall, where your hood needs fixings, drill and use the toggle bolts suggested earlier. You might be able to use a mix of the above, plug toggle bolts. The problem with toggle bolts is - if you ever take the hood off the wall, the bolt wings will be lost in the hole. Perhaps a better idea, is a version which stays put - Like an expanding rubber sleeved nut. You just drill a hole, push the rubber nut in, and tighten up.

20mm is plenty for a plasterboard fixing to hold in.

Check out hollow wall anchors

But equally we don’t really care if toggle nuts drop inside the wall, just use a new one

Aye, missed that

Can alternatively multitool a large square out of the wall, fit ply or noggins behind (ply larger than the hole, glued n screwed to plasterboard) and then replace the plasterboard square and filler

Did you miss 'and an 8mm splash back, on top of the PB'?
