Preventing rear window breaks

No need for it to be too thick. Mine came from Bunnings & its about 3 to 4 mm thick. I could not get suction caps to work, so I use duct tape and remove when we get back onto the black top.
Have also used cardboard, beer cartons & one of those roll up sun deflectors that you put over the dashboard, it worked for a full 3 week trip.

Gidgee, Do you need to see out the back??

If not then anything that will absorb a rock strike will do!

If you want to use something clear then use polycarbonate sheet (Lexan) doesn't bleep ter like Perspex & lasts longer 2/3mm will do, use blobs of silicon sealant to stick it on, put then near the corners, & when you want to get the sheet off then run a thin blade through the silicon & scrape the rest off with a razor blade, or you can get the self adhesive Velcro tape from supercheap as an alternative!!

Like Jeff has said, the silicone is the best way to attach it. Make sure that if your glass is curved, the perspex is spaced away from it (with the silicon). The glass will scratch and pit from dust and sand that gets in between the two if they are allowed to touch.

Although I use a commercial product, (Obies Outback Rear Window Saver) provided you can source a suitable bleep ter proof product, there is no reason why you cannot make your own.

The perspex only needs to be about 2-3mm thick and the best method of attaching it is by Velco Spot Hook & Loop fasteners. These are available at most hardware outlets and are about 22mm diameter.

If sections of the screen "touch" the glass, support (space) them with small clear self adhesive spots attahced to the perspex in a few places.

This method allows you to remove the screen between uses and the only thing on your window will be the dots around the edge of the glass.

I recommend you put the Hook spots (the rough feeling ones) on the screen and the softer Loop material on the window glass. This makes for easier cleaning of the glass, without leaving bits of sponge stuck to the "hook" material.

I bought a sheet of corflute from a sign-writer for next to nothing and cut it to fit glass size and shape. Used self-adhesive velcro dots.

Can't see thru it, but it was otherwise ok.

I used double sided auto tape to attach my protector.

Came off easily and the remaining tape easily removed with turps.

Hello

I use a perspex protector cut to suit my vehicle. To date I have attached it using velcro type products with the adhesive backing, all of which have proved to be a dismal failure because in the heat ,the glue can't handle the pace on the window and the whole thing sags after a while. I am still trying to find a better way of keeping the perspex attached to the rear window. My next scheme may involve using non adhesive backed velcro and aralditing the non hook part to the perspex, sticking the same stuff insided the rear door in strategic places with selastic and using lengths of the hook part between the two.

I eagerly await some better solutions

Clear plastic sheeting from Spotlight or similar fabric/craft store. The self adhesive Velcro does come off the window when it is really hot, but Velcro brand lasts letter than cheaper alternatives. We didn't loose the covers the Willem made for us as only the odd one came unstuck, so stopping and pressing it on tight again worked well.

I had some Perspex cut to fit the rear of the GU, and used the Velcro Dots. The main problem the windows are curved and the Perspex is flat, so after a day in the heat most of the dots pulled apart. In the end I took the sheats off and through them in the back.

Never got a broken window or stone chip on the back doors due to the well designed stone deflector on the camper. I don't think I will use them ever again.

My driving lights always used to smash when hit by stones (esp on gravel roads), so I bought some clear 3m film (about 5mm thick) to put over the lights. Never had a breakage in 100,000km's after that.
Got it from Autobarn, and I have seen sheets large enough to fit over a rear window.

It's a permanent solution, that you can see through quite easily.

I was using perspex attached using suction cups...
Found the dust getting between the perspex & glass to be a real PITA....
(towing a camper, vehicle is never loaded above window height, and I like to be able to see out the back window)....

Got some "Light-Skinz" film (ordered mine from Repco, you can get pretty much any size you want), made a template, cut film to shape, & stuck 'er on...
It's (semi) permanent, been on over a year, & still as clear as the day put it on.. remains to be seen how long it'll last before it goes hazy/cloudy, but if/when that happens, it can be removed with the aid of a heat gun (or hair-dryer) and a new lot applied...

Beats the perspex idea hands down, IMO.... (YMMV)

G'day - having broken a rear window - we put the cart before the horse and got ourselves some stuff called "Tuffek" - from a perspex guy locally - quite cheap - we use adhesive velcro (the velcro brand is the better buy) - but we take the protector off when we are not towing - for the same reason as someone below mentions - the hot sun will melt the glue and the cover can slide off - we always carry extra velcro - because it doesn't last forever and it is pretty easy to replace.
Works for us - better than another $1000 approx for a new rear window.
