Wall anchors for insulation backed gypsum; advice needed.

[FACTOR]

Hello.

I need to hang curtains and curtain rods. My walls are 9 mm of standard gypsum and then backed with 35 mm of high density insulation; total thickness is 44 mm.

The curtains are not terribly heavy, (but they are block out material), nor are they super lightweight gauze type material. I want something fairly strong.

Any suggestions on what type of wall anchor and screw I should be using?

Thanks.

9mm is their standard board and use it everyehere.

I went looking for 12mm at global and thai watsa but they dont stock it.

A curtain only a metre wide will struggle to cling on to 9mm.

The safest solution is to fix a 2x1 timber pattress to the plasterboard. Drill and fix it using plasterboard anchors or butterfly type plugs.

Then you can drive in a dozrn screws to spread the point loads.

Paint it and then simply screw your curtain brackets to the pattress.

Seem to remember a plug type fitting which was like a large gauge spiral whcih could suit but forget finding them eyecatcher's suggestion likely best and spread the load

This is a UK company but these are available here.

There are many shops selling plasterboard (gyproc) so maybe best bet. Places like hompro., thaiwatsudu dunno!!!

Those screw-in plugs is exactly what I was on about, but pattress likely still the best idea.....perhaps fixed with these fittings?

I use these:

Bought them at Home Pro. It distributes the load behind the wallboard and are available for different thicknesses of wallboard. Metal ones are also available and are the same for all thicknesses as the screw starts the clamping action:

One more thing not yet mentioned: your gypsum wall must be supported by studs... so maybe a stud finder is a good idea?

for the reason that you need to avoid them!

the studs here will be tin metal so you plastic plugs are not going to win that battle of strength. Thats going to be a nuisance as will using self tappers to fix into metal.

As i said avoid those studs as they are a hindrance. (You should be able to see the stud positions in plasterboard if you look for the screw positions, usually filled and shrunk slightly.

Hrmm, the studs we've always used (Mor Or Gor spec) would take a lot of pressure before they'd buckle or let go of a screw (note: no need for an anchor) - surely stronger than a screw and anchor into flimsy 9mm gypsum?

I agree, if there is a stud in the correct location use it. If the stud is metal use a metal self threading screw. The stud will act as an anchor and spread the load over a larger area than a hollow wall anchor will, the studs won't buckle!

I'm doing the same project as you but my wall is Q-Con. What do I use to attach to Q-Con?

We only use resin anchors in QCon - anything else just doesn't bite & hold.

Can I get them at Homepro? What do they look like?

It looks like two cans - one the resin, the other the hardener - you drill a hole, fill it with mixed resin, then insert a sleeved bolt anchor. Wait for the resin to cure, and it'll never come out.

Thanks for that explanation. Can this product be purchased at Homepro, HomeHub, Thai Watsadu? Who makes it?
