Breathable

When you let your house breathe, that is, create the natural conditions for its breathable structures, your house will be healthy for a long time. Finnish examples of this are the warm log buildings and wooden buildings that have lasted for hundreds of years. Ekovilla insulation lets the structures breathe.

In winter the breathable Ekovilla keeps the indoor air humidity at a pleasant level

In summer the breathability keeps excessive humidity outside

Why is breathable good?

A breathable structure is good for health and the life in a breathable house is properly oxygenated. A well-made breathable structure is airtight – it does not allow extra air to pass through the structure into the rooms. A breathable house improves the indoor air by affecting its key factor: indoor air humidity, which in turn has a significant effect on the following:

Comfortable temperature and living conditions for the inhabitants
Sensory detection of air quality (pleasant/unpleasant smells, freshness/staleness)
Durability of materials
Energy consumption

How breathing structure works?

Natural moisture control and drying ability

As ability to bind, transfer and release moisture, as well as the ability of a structure to dry.

There is moisture in the air, invisible water vapor that penetrates all spaces. The humidity of the room air varies, as does the humidity of the outside air. Moisture tends to balance itself, meaning the water vapor moves to where there’s less of it.

It is impossible to completely prevent air moisture from entering the structure. Therefore, it is wise to choose an insulation material that is capable of binding and transferring moisture in a natural way. Ekovilla, which consists of a wood-based material, has this ability.

Although wood fiber has a high moisture capacity, it does not store the moisture, but moves it in a direction where there is less moisture. Thus, the humidity inside the insulation does not normally exceed the humidity of the outdoor or indoor air. Under these conditions, Ekovilla acts as a normal thermal insulation.

The optimum indoor air moisture varies throughout the seasons between 28-40%

The green scale shows measured air moisture in a bedroom with a breathable structure, and the grey one the same for one with tight structure.
