Reference design PCB thickness and material

Question

What is the recommended PCB thickness of the nRF51822-QFAA Reference Layout? It'd be great to have a specification in the package including the full spec of the PCB material that Nordic uses (dielectric constant @2.4GHz, etc).

The EV/DEV kits that we supply are mostly with 1.6 mm PCB thickness (PCA10000 dongle is .8).
The discrete reference layout will work with thickness from 0.8 - 1.6 mm.
We have seen designs down to .6 mm as well, which had no performance issues. 
 PCB material is normal FR-4. Different manufacturers have different spec for dielectric on FR-4.
I believe our supplier specs dielectric of 4.6 nominal.
