Breathe Easy: Unveiling the Breathability of Lime Plaster for Home Walls

Posted on 27-Jun-2023

When it comes to creating a comfortable and healthy living environment, the choice of wall plaster material is a critical consideration. While factors like durability, aesthetics, and maintenance are commonly taken into account, the breathability of the plastering material is often overlooked. However, understanding the importance of breathability can significantly impact the overall quality of your home. In this blog post, we will explore the benefits of lime plaster, an exceptional material known for its high breathability, and the unique advantages it brings to your living space.

What is Lime Plaster?


Lime plaster has been used for centuries in construction due to its excellent properties. It is a mixture of lime, water, and aggregate that creates a smooth, durable coating for interior and exterior walls. Unlike modern plasters, lime plaster is made from natural materials, making it environmentally friendly.


The Breathability Factor


One of the standout characteristics of lime plaster is its exceptional breathability. Unlike synthetic materials that trap moisture, lime plaster allows the walls to "breathe." This means that it enables the transfer of moisture vapor in and out of the walls, creating a healthier living environment.

Here are some key advantages of the breathability of lime plaster:

  • Moisture Regulation


Lime plaster acts as a natural moisture regulator, absorbing excess moisture from the air and releasing it when the environment becomes drier. This ability to regulate moisture helps prevent the growth of mould and mildew, which can be detrimental to both the structural integrity of the walls and the health of the occupants.


  • Improved Indoor Air Quality


The breathability of lime plaster contributes to improved indoor air quality. By allowing moisture to escape, it helps maintain optimal humidity levels, reducing the risk of respiratory problems and allergies. The constant exchange of air also prevents the buildup of pollutants and odours, creating a fresher and healthier living space.


  • Preservation of Building Materials


Another significant benefit of lime plaster's breathability is its ability to protect and preserve the underlying building materials. Moisture trapped within walls can cause damage over time, leading to decay, rot, and even structural issues. Lime plaster acts as a barrier, allowing moisture to evaporate and protecting the longevity of the walls.


  • Thermal Comfort


Lime plaster's breathability also contributes to thermal comfort within the home. By allowing the walls to breathe, lime plaster helps regulate temperature and humidity levels. This natural insulation property helps keep the indoor environment comfortable, reducing the need for excessive heating or cooling.


Breathable Lime Plaster: Enhancing Thermal Comfort at The Taos Pueblo


The Taos Pueblo, located in the high desert of northern New Mexico, showcases the benefits of lime plaster in maintaining a comfortable living environment. The multi-story adobe buildings, coated with lime plaster, have stood for over a thousand years.

In the scorching summers, the lime plaster absorbs and dissipates heat, keeping the interiors cool. During freezing winters, it acts as a natural insulator, retaining warmth inside. The plaster's breathability allows for moisture regulation, ensuring balanced humidity levels.

The Taos Pueblo exemplifies the sustainable use of lime plaster, enhancing thermal comfort while preserving the historical integrity of the structures. This ancient village serves as an inspiration for modern construction practices seeking breathable materials for natural temperature regulation.




Lime plaster's exceptional breathability offers numerous benefits for home walls. From moisture regulation and improved indoor air quality to the preservation of building materials and enhanced thermal comfort, lime plaster proves to be an excellent choice for those seeking a healthier and more sustainable living space.
