It’s spring and you’re sitting in your conservatory that doesn’t have blinds. The outside
temperature is 20 degrees Centigrade and partly cloudy. With clouds covering the sun the
conservatory remains relativeley comfortable, however the moment the sun comes out you
will almost immediateley feel hot and uncomfortable.
This in a phenomenon called ‘Instantaneous Heat Gain” where your body heats up far be-
yond your surroundings. The room temperature certainly hasn’t risen that much but the
effects of the sunlight on your body has caused you to feel a lot hotter than the room.
Any conservatory without some sort of shading will be very uncomfortable on a sunny day

materials used in conservatories there is the additional problem of glare.
The sun emits short wave radiation that changes to long wave as it passes through the win-
dow onto objects in the conservatory. The long wave radiation bounces off these objects
and unable to pass back out through the window causing a build up known as the
‘Greenhouse Effect’ which can make rooms, particularly conservatories very hot and un-
So how can you take control of your conservatory and use it even on the hottest sunniest day

The only effective way to control the climate in your conservatory is with some type of roof
