All of us have heard of rain screens and how they are helpful in protecting your house from damage due to the rain. The entire system forms a dual protection for the wall of your building. Additional insulation is also recommended. Architectural facades, for instance, can work wonders – but you need to know where and how to use them.
The Air Blanket
The first line of defense that the rain screen offers is the sheet of air over the wall. This is created by a couple of methods. The ventilation needs to be maintained with extra care when there are windows and wall penetrations as a part of your building.
A double layer of outer and inner sections makes sure that the air insulation is kept all around. The outer layer keeps the rain out and the inner layer forms thermal insulation. This ensures that the frame of the building is dry.
Furring is one way to create this air blanket. This is done using vertical battens or strapping. The openings made on the bottom and the top of the wall thus the rise of air happens naturally.
The rain screen forms a layer of air over the surface of the wall, so that the water does not come in direct contact with it. The additional layer of insulation is needed because of sometimes, there is a possibility of some amount of moisture coming in contact with the wall. This can cause the growth of mold on your walls.
Getting Rid Of The Water
The water is the reason why so much damage comes to buildings during monsoon. It penetrates into the material and creates a path for other elements to start affecting the building as well.
The drainage system is designed in a way that even the heaviest flow of rainwater can be directed outward and away from the walls of the building. A special drip edge called flashing directs the water away from the edge. During intense rains with high wind velocities a minute amount of rain may penetrate through the air insulation system and reach the cladding.
However, the water resistant nature of the cladding ensures that these droplets move towards the ground due to gravity and surface tension.
The pipe system has to be quick efficient and long lasting. Water, when unfriendly is a very destructive force. It is the nourishment that other degrading components need to take root on a surface. Thus, the maximum amount of water needs to be gotten rid of.
Care needs to be taken during installation so that the drainage plane stays rigid and is not susceptible to compression as this will affect the air blanket.
