Climate in conservatory

Glass surfaces are assuring winter garden enough light and allow sunbeams to enter and warm up the place. Temperature and air moisture must be appropriate for plants to grow successfully and for us to enjoy the view. Climate depends on type of conservatory.

Sun dictates climatic circumstances within conservatory. It is driving air circle inside it. There is day and night cycle that can be used to warm house in colder time of the year. Sun is warming up air by day, which then travels into the house in upper part. Cold air returns in lower part. At night doors are closed and cold air isn't penetrating to the internal places. It is possible to save quite significant amount of money for heating this way in autumn and spring.

Ventilation

Good ventilation is essential for any conservatory. It should be foreseen in stage of planning. Correctly planned and versed ventilation system ensures the permanent exchange of air humidity through the year. Temperatures too high and too much moisture will make fungus grow.

Ventilation system must be adapted to size and shape of conservatory. Basic rule says that at least 10 % of glass surfaces should be windows that can be opened. Windows should be on side walls not too high and on the roof. Through side windows enters cold air and through roof windows exits hot and moist air. Windows can be opened automatic when temperature gets high enough or we can open them by hand. Better solution is automated system as it works independently.

Shading

Conservatory works as a hotbed (restrains warmth) and in hot summer days it can overheat. Even opening all windows will not keep the temperature at appropriate level. Therefore we must install and use sunscreens.

Shading is most efficient from outside. Sunscreens are installed on glass elements from outside. Such shading is most efficient, because it prevents entry of sunbeams into conservatory. Outside sunscreens are most expensive and demand regular maintenance.

Internal sunscreens as venetian blinds, plises or curtains are simpler to install and maintain but are less effective as they warm up and heat internal air.

If there is possibility of arranging natural shading, we should do it. Natural shading can be provided by a tree or trees planted in front of conservatory. It is important to use deciduous trees to allow direct sunlight in winter to reach conservatory.

Natural shading has numerous disadvantages. If conservatory is large, one tree won't be enough as only part of it will be in shadow all the time. If tree is planted too close to construction, roots can hurt floor plate and foundations. Leaves will be falling on glass surfaces in autumn and a lot of cleaning will be needed.
