If you can't stand the heat, keep out the sun; TRICKS of the TRADE.
WHAT'S an effective way to cool down my house without the use of air conditioning? George Nyman, Leeds
ZENA SAYS: Insulation works both ways, keeping a house warm in winter by not letting the cold in and cool in summer by not letting the heat in - so that's a good place to start.
Because warm air rises, it's a good idea to open both downstairs and upstairs windows to create a throughdraught.
Marcus Pickering, of Factotum Homes (0845 119 2999), says that if you want to open a ground-floor window but are worried about security, you can buy catches that allow it to open a little but no further.
He also suggests preventing sunlight coming in through the windows in the first place, using either shutters or even just thick curtains.
The simplest things like opening windows and closing curtains can keep you cool
