I remain unconvinced.

Im interested to get one put in the house here.

Simple way to keep a house cool, at least for several hot days, is to
keep windows closed and pull down blinds, during the heat of the day. On
an evening, once the outdoors cools down some, open the windows.

+1 for all south-facing windows.

North-facing widows can be kept open because the air is cooler
being in the shade.

During the hot spell of last week, indoors it never exceeded a
comfortable 23.5C, when I was recording 31.5C outdoors.

The back of my house, facing south did get hot. The heat coming
through the patio door *glass* was incredible. The back wall
was covered in a huge rampant passion flower plant but I had to
remove it because it was rampaging into the loft, which was up
to 47C at one point, while my Brannan mercury wet/dry thermometer
was reading 26C dry in the lounge, facing North.

last year this climber made all the difference by shading the wall
and also partially shading the patio doors and kitchen window.

I'm going to get one of those 'sails' that are very common
in Oz and fix that to the back wall and lash it to the birch tree.
