Fitting roller blinds in conservatory

[Jen99]

Got three roller blinds for my sun room/consevatory. What is the best way to fix to the upvc (or whatever it's called)? Will the screws supplied do the job?

We don't know what screws were supplied you omitted that detail.

Screws are silver about an inch long with the thread all the way to the head. Look like posidrive. Come with grey rawlplugs.

You may get away with drilling into the upvc directly, but of course there could be an aluminium extrusion beneath.
So - drill a small pilot hole, say 2.5 mm diameter and see what the drill bites in to. If you think you can get a fixing, increase the size of the hole until its the same diameter of the screws, minus the threads if you get my drift. The screw must cut its own thread into the hole and ideally will be of the self tapping type (which sounds like what you have).
Use a new drill bit - you need to get it right first time!

Ok, thanks, will try it that way. Must be possible, next door has similar sunroom with venetian blinds. But her hubby is in care home and she has no idea how he did it. I can't determine if these screws are self tappers or not. Will try them if they fall down can buy more screws!!

The screws may be too long, tighten slowly as if they hit a second section they cannot penetrate they will churn a hole and become loose.The screws need a coarse thread.
