There is no such thing as as insulated roller shutter door.

Mine is insulated. There is foam insulation between the inner and outer
faces.

The problem arises round trying to make them draught proof, (no point
in being insulated if they are not draught proof).

Mine has brush types seals built into the guides and a seal with the floor
at the bottom. The only part which does let the draft in is along the top -
my fault, I just never got around to dealing with that.

Mine has the motor in the middle if the roll, with the control gear in a
separate box. It rolls up into a roll of about 9" diameter.

The side guide rails I fitted flush to the inside the front of the garage,
so as not to restrict the width.


Sounds very similar to the one I had fitted, on a hot summers day when all
the exterior metal work is hot the inside of the shutter takes a longtime, if
at all, to warm up. So I believe that the insulation must be doing something
:-)

A big plus point with it is that before I had an up and over door and this
restricted where I could have racking mounted, I now have it right up to the
doorway.

I agree, they are much more compact than an up and over door. In my
case the up and over had been on its last legs for several years. I had
fixed it numerous times. I priced up the options and the electric
roller was not much more than and in some cases cheaper than the other
DIY options.

The controller has crashed a couple of times over the years, failing to
work via the remote, which has meant my entering by another door to
reset it. Other than that, no issues at all.
