Walls have the biggest effect on a building’s overall environmental impact. They are also responsible for most of the heat loss from a house.
Ecotech normally consider the breathability of the walls as breathable walls can help to offset the highs and lows of humidity caused by modern living, helping to promote a healthy internal environment.
Ecotech   choose to design & build a breathable wall, we must make sure that the moisture is always drawn outwards, not directed inwards into the building! This can be achieved by using different renders on the internal and external walls.
