Any suggestions for a wood construction workshop 4m x 3m size

The workshop is basically a large heavy duty shed with a UPVC door and
UPVC window with no internal insulation.

Any ideas or suggestions welcome

Without any insulation, the only type that will be remotely efficient
would be infra-red. i.e. try to heat yourself without heating the air.
It works reasonably well if you're doing something fairly active, but
it's a bit crap if you're not moving much.

Why not insulate it though? My shed is a bit over 4m X 2m. It's
insulated all round (including floor and ceiling) with cheapo
polystyrene under plasterboard and it's nicely heat-tight. I put in a
3kW convector for a fast warm-up, but it'll easily maintain a nice cosy
temp on a mid-winter night on the 1kW setting. The room thermostat
barely has it turned on once it's warmed up on most nights.

Cheers,

Colin.
