If you want to keep your house cool in summer without cranking up the energy-hungry cooling you have got to stop the sun hitting the glass.

If you're not quite up for the expense of awnings but still need to stop the hot-house effect this is the GIY job for you. We use a product called renshade, stick it up on your windows and skylights and it reflects the heat back out. For more energy saving DIY jobs go to www.greenityourself.com.au
