Cooker Hood into Plasterboard

[thebadger7]

Hi guys

I'm trying to fit a 13kg cooker hood into drywall. It's plasterboard on battens on brick, but with foil insulation in between.

I was planning on drilling all way into brick but the insulation gets all caught in drill bit

I can get a fix with one screw on a timber. So with this, and four fixed into only the plasterboard, would this suffice do you think? Attached pic of wall

Thanks

Luke

Spring toggle fixings would probably be OK. They don't give them load ratings but 13kgs isn't very much so if you can get a few in then it should be adequate.

Alternatively, if there aren't many fixings points, you could put up a plywood backing board which connects directly to the studs or again use the spring toggles.

Again, Corfix are my choice of fixings...

Doesnt matter if you get insulation on the drill bit.

Thanks all - insulation clogs up drill bit to the point which it stops being effective and can barely get it out, not to mention breaking the vapour barrier

Don't think corfix would work anyway as its more than 45mm to brick even if I could get nicely through the foil insulation

Corefix come in different lengths...

You do not want a [vibrating] heavy cooker hood held solely or partly to plasterboard.

Thanks all. So I went with ply, cut to span three studs. I then attached the hood to the ply. Seems pretty secure, only concern is the steam from cooking hitting the ply. I suppose I could chase it into plasterboard, but you can't see it behind hood

If i was using ply, i would seal it first.

With a wood primer?
