This cold snap has focussed my mind on improving the insulation of my garage
and I am thinking of replacing my current up and over door with an insulated
sectional door. I had a look at the Hormann information on the web and see
that they fit behind the brickwork.
I fancy having a go at fitting one myself and wondered if anyone has any
tips etc. Is it a one man job or does it need and extra pair of hands?

The current door has a wooden frame which I presume will just be removed.
This will leave a gap on one side where the rendering meets the frame. The
other side is OK as it is facing brick. Any idea on how to cover/ fill the
gap. The other possible problem I see is with the panel above the door. It
seems asbestos like material but is probably cement board stuff ( I don't
know the name) which is nailed to the lintel of the door frame. I guess
that trying to remove the lintel will damage the panel. Has anybody
attempted a similar installation?
