Celotex GA4000 - printed side in or out?

[walty666]

Hi,
I'm currently fitting Celotex GA4000 between wall studwork and roof rafters in my garage. It's foil backed on both sides. One side is printed. Does it make any difference which way round I install it (i.e. printed side facing in/down or out/up?). Have signed up to Celotex website to get access to their Handy Guide but can't easily find the answer?
Thanks
Ross
