Patio door security - How to beef it up?

[ubdai]

In my lounge I have a sliding patio door like most people I would assume. However the bit that slides is on the outside of the unit. And it has just a normal one piece locking mechanism, no additional bolts or anything.
Seems a lightweight uPVC and am a bit worried by using something like

Just in case the door plastic can't take the fixing. What would be the best method of fixing a patio door lock to the plastic door frame.

Question - How can I make the door more secure.
ie to stop the door being forced back along its runner or being forced up and off. (At present I put a piece of wood and jemmy it into place between the sliding door handle and the fixed frame of the other half).

Thanks

The sliding bit should have been on the inside.

We used to put a bit of wood tightly in the channel at the base & top to stop it being forced to slide & two wedges in the top to stop it being forced up & out of the track.

I guess you need to lock it to the handle end as normal but also to the fixed bit at the bottom both sides to stop it being lifted.

Best to get the insurance company to advise you. After all they are the ones most likely to pronounce on the efficacy or otherwise of the installation.

Local Crime Prevention Officer may advise as well.

Just found out a work colleague has exactly the same type of patio door (Slides on the outside). And he's had someone try to jemmy it open.

We are both now looking at getting a 'safeslider' from across the pond.

You also need to insert some sort of packing in the gap between the top of the door and the frame so that it cannot be just lifted off the sliding track.
You can buy stepped blocks for this eg (http://www.lockcentre.com/8k122-chubb-patio-door-anti-lift-device-p-170.html) or just use a piece of PVC /aluminium section if you are lucky with the size.

No... alot of examples have the sliding bit on the outside.

we have

However its still no good.  A well positioned pick or shovel will move it.

I have put in a lattice fold-able grill.  I know many people may think its OTT but even if the door fails they will need an angle grinder to
get through that.

they really don't say anything except for the main and rear doors being 5 lever and having window locks...
