Jablite is cheaper, and probably adequate for a garage.

Thanks everyone for your suggestions here - Jablite is quite cheap.
Any idea how that material can be fixed to a vertical surface?

Siroflex PU foam drywall adhesive - an expanding foam with low expansivity.
I'm not sure if it would attack EPS (jablite) but I'm happy to try a bit
for you.

Otherwise, screws/nails and *big* washers (like 30mm+ big).

Or surface it off with ply and screw the ply though the EPS into the wall.
Jablite is good in compression. If you use heavy ply this would give you
the advantage of being able to fix shelves (upto a point) to the ply,
especially of the ply is supported along the bottom edge.

(Better for shelf fixing) - batten the wall out, infill with jablite and fix
ply to battens. You now can fix heavy shelving to the battens if required.

Certain tile adhesives will stick passably to EPS too - including Mapei
kerabond (I've tried) so a dot'n'dab approach might work too.

Or look out for "2nd grade" celotex (I have some Ballytherm - same stuff,
few dints, but just as good from any practical POV). Same fixing methods
apply.
