Is Green Guard Thorn Proof?
Schwalbe Tyres offer many of there tyre models equipped with Green Gaurd, a 3mm, partially recycle latex rubber shield, that is installed between the tyre carcass and the tread.
It does not prevent punctures from thorns. At least not completely.

The Thorns
Hawthorns and black thorns are a common species included with UK hedges. In the autumn and winter UK farmers are free to trim their hedges. The reason that the trimming is undertaken in the winter is that it does not interfere with nest birds.

Typically a mechanical flail hedge trimmer is used to trim the hedge, bit of hedge fly all over the place and inevitably 50% of it ends up on the road.
Not only are they sharp and spiky, they also land with three of 4 thorns set at angles around a twig, meaning they sit on road, perfectly angled to puncture a tire.
The Tire
I recently purchased some Schwalbe Super Moto X Tires, as they have a green guard protection layer and I thought this might prevent thorn punctures.
No it doesn't. The thorns go straight through. This thorn went straight through the very central area of the tire, where the green guard layer is thickest.

Conclusions
I would not buy green guard tires to protect against thorns specifically, you might choose nay other puncture protection system. They may help prevent lots of other punctures, and perhaps they might reduce the probability of thorn punctures, but they wont stop them. Ciao ciao
