The principle of rear ventilation
In combination with a properly designed roof construc-
tion, the EasyIn system guarantees optimal ventilation at
the rear of the roof surface. Air inlets located in the eaves
allow (e.g. through bird guards) ambient air to fl ow in-
wards between the EasyIn System and the roof sub-con-
struction.
As the air heats up it rises due to its lower density, and es-
capes through the ventilation openings at the roof's ridge
or the ventilation tiles to be attached. Colder air (with
higher density) is sucked in from below to compensate
the pressure diff erence resulting from cold/warm air tran-
sition. This natural convection (=chimney eff ect) ensures
that the SOLARWATT EasyIn system is cooled suffi ciently
guaranteeing optimum performance even at high tem-
peratures.
