Cork is a fundamental identity element at Diasen, the precious raw material that drives the quality of our products. Incredibly versatile, cork has found an innovative use in the green building and architecture sector, providing a real alternative to the risks of cork production.  

Thermal insulation with cork: performance and liveability

Cork, combined with other natural materials in the form of biomalta, can guarantee important performance in terms of thermal insulation. Still, it is also characterised as a sustainable, ecological and renewable material that stands out for its ability to reduce the environmental impact of construction activities.

But what makes cork so special when it comes to thermal insulation? Firstly, it must be said that cork is a material with low thermal conductivity, which means that it is able to limit the passage of heat through walls, thus reducing energy loss and ensuring better living comfort.


All thanks to high porosity

Cork has been used for centuries as a thermal insulator: thanks to its honeycomb structure, it offers exceptional insulation capacity due to the air incorporated in its structure.

Cork consists of a chain of hollow cells filled with air, which makes the material particularly light. This leads to cork having a very low thermal conductivity value, which enables it to retain heat within the structural matrix.

At Diasen, we use cork because it reduces heat loss to the outside during the colder months and slows it down in summer. But the properties of cork are not just limited to thermal insulation. Cork can also prevent the formation of moisture and condensation, reducing the possibility of unhealthy mould growth in walls.

In short, the excellent performance of cork allows for thermal and acoustic insulation, resulting in dry, mould-free rooms, keeping the home healthier and more comfortable for its users.


Versatile and elastic: the characteristics of cork

Another factor that contributes to the performance of cork as a green building material is its elasticity.

This allows cork to adapt without structural changes to thermal stresses and variations in temperature and humidity while maintaining its insulating properties intact over time. In this way, cork is able to provide effective thermal protection without suffering any deformation or reduction in performance.

This reduces building maintenance requirements, saving money, and reducing the production of waste materials released into the environment. Cork has a very sustainable life cycle and its durability makes the building sector even greener.


Not only living comfort: sustainability is the watchword

Cork is not only an outstanding material from a technical point of view: it is also a material that stands out for its environmental sustainability.

Cork is a natural material with a long and sustainable life cycle in all its phases. It is a bark, regenerating every ten years, produced by a specific type of evergreen oak that thrives in certain regions of the Mediterranean, particularly in its western area. The use of cork is an age-old tradition which has an impact on the lives of local communities, who derive part of their income from the cultivation of cork trees.

It is therefore a 100% natural material, obtained from the bark of a tree without the use of chemicals or substances harmful to the environment. In fact, the cork extraction does not harm the plant, which renews itself naturally in its own time and manner. Once used for its own purposes, including in the construction sector, cork can be renewed, recycled or disposed of without harming the environment.

In short, cork is born from nature and returns to nature once its task has been accomplished. The magic of this material lies in its long tradition, ever since ancient nomadic peoples used it as thermal insulation. It has come down to us and allows us to embrace the ecological transition to greener and less emissive building.


Cork in the service of comfort and savings

The home is where we spend most of our time, a refuge where we rest and regenerate. Therefore, the home must be a healthy, comfortable and safe environment for our health and psychophysical well-being.

Biomaltenes and cork-based paints have a long lifespan and require very little maintenance, making them an excellent long-term choice for anyone looking to make their home more energy efficient and comfortable for the well-being and comfort of the whole family.

Temperature is an essential factor in ensuring living comfort. Too high or too low a temperature can in fact cause discomfort and stress, compromising the quality of our daily life. Moreover, an inadequate temperature can negatively affect our immune system, increasing the risk of contracting diseases.

The use of biomass and cork-based paints makes a difference: the house maintains its thermal balance better.

This means you will not have to use too much electricity or gas to achieve an adequate microclimate in your home. Thanks to applying biomass and cork-based paints, you can save on your energy bill.

Choosing cork as a thermal insulator means investing in an environmentally friendly and sustainable solution that is more energy efficient than traditional materials and provides an exceptional microclimate tailored to every need.

The home maintains a suitable microclimate that is dry and free of bacteria that could endanger the health of the occupants. Mould and bacteria can cause respiratory problems, allergies and skin irritations, especially in more sensitive individuals such as children and the elderly. In addition, humidity can encourage the proliferation of insects and parasites, increasing the risk of diseases transmitted by these pathogens.

Cork for thermal insulation is an extremely versatile material that adapts to all kinds of structures and requirements. It can be used for thermal insulation of walls, ceilings, roofs and floors, offering a tailor-made solution for every room and every comfort requirement.

Then choose Diasen cork-based products. We have been experts in thermal insulation for decades and support families in their quest for living comfort, environmental sustainability and energy saving. We know how important it is for you to have a cool house in summer and warm in winter, free of humidity and acoustically insulated.

Our biomalta and cork-based paints are the best solution to meet all these needs. Find out more on our website or contact us for advice on the best solutions.
