Terracotta: an eco-responsible material for a façade

Terracotta is an eco-responsible material with many advantages. The first advantage of terracotta is its bioavailability. Indeed, terracotta is made from clay. As clay is a raw material found in abundance in the soil, it is identified as a renewable and biosourced resource and therefore eco-responsible. 

The second advantage of clay is its high insulating power and inertia. When used in the construction of a façade, terracotta provides thermal comfort in all seasons, day and night. During the day, the terracotta façade stores heat in its walls while keeping the interior cool. During the night, this heat is diffused into the building. This heat restitution at night and on cool days means that a heating and/or air-conditioning system is not required.  

The 2020 Regulation, also known as the RE2020, defines the various building standards that will be in force from 1 January 2022. These standards encourage the use of eco-responsible materials such as terracotta. The excellent thermal performance of terracotta provides many good points for the calculation of the Bbio. The use of terracotta in an eco-responsible construction is therefore highly recommended. 

The third advantage of terracotta in facades is its durability, requiring almost no maintenance.  

Finally, terracotta used for facades is healthy for users, as it does not emit VOCs (Volatile Organic Compounds). As it contains no colouring agents or additives, it presents no danger of toxicity for humans or animals. 

Terracotta provides lasting protection for buildings

Terracotta has been one of the most widely used materials for building and renovating facades for centuries, as it is not subject to weathering. It is perfectly resistant to high temperatures, but also to frost, torrential rain, shocks and UV rays. Depending on the climatic conditions, terracotta may have a slight patina over time, but this does not alter its properties in any way.  

Another advantage of terracotta in facades is that it is a naturally anti-fungal material. When used for the construction or renovation of a façade, it allows the building to breathe. The air circulates perfectly and does not stagnate. The risk of condensation, fungus or mould is therefore virtually non-existent.

Using terracotta for a facade renovation

On average, a quarter of the heat generated inside a building is lost through the walls. This energy loss is harmful to the budget and the environment. In order to remedy this unnecessary and harmful expenditure, it is possible to act on the insulation of the building by installing an ITE. An eco-responsible and sustainable material, terracotta considerably improves the thermal performance of the building when used for façade renovation. By cutting thermal bridges and thanks to its intrinsic inertia, energy savings are significant.
