ROOF ACCESSORIES: VENTILATION AND VENTILATION PROTECTION
There are many factors to take into account when designing and building a safe, healthful, and durable roof: ranging from the building tradition of the place where the roof is built, through the experience of the builder to the specific requirements of the client.
Good ventilation helps the water vapour inside the building envelope to dry, preventing the formation of interstitial condensation at the insulation of the structure. In winter, ventilation makes snow that may have accumulated on the roof to melt evenly, preventing it from slipping uncontrollably. During the warmer months, on the other hand, ventilation removes some of the thermal energy stored under the roof, contributing to improved housing comfort.
The ventilation layer offers additional protection in the event of accidental infiltration, as it creates a second layer of water flow and prevents water from stagnating, the small details then help us protect the air intake and exit points from the entry of insects, birds and obstacles (such as leaves) that could prevent the free circulation of air.
