Silicone Render vs Monocouche Render

When it comes to the world of construction and architecture, the type of render you select for a building can profoundly influence its durability, aesthetics, and overall functionality. Two popular types of render on the market are Silicone Render and Monocouche Render. Both of these materials have their strengths and weaknesses, so understanding them in detail is crucial before making a decision. This article aims to offer a detailed comparative guide of Silicone Render and Monocouche Render to help you choose the best for your specific needs.

What is Silicone Render?

Water Repellency: What sets silicone render apart from other types of render is its high water repellency. Its hydrophobic properties help protect the building from water damage, preventing dampness, mould, and algae growth. This makes it particularly suitable for buildings in areas with high rainfall or high humidity.

Flexibility: Silicone render is also characterized by its flexibility, which makes it less prone to cracking from building movement or temperature fluctuations. This attribute is particularly beneficial for older or timber-framed buildings that naturally tend to shift over time.

Aesthetics and Maintenance: Silicone render is available in a wide range of colours and finishes, providing great flexibility in achieving the desired aesthetic look. Additionally, due to its water repellency, it’s less prone to staining and discolouration, which means it maintains its vibrant colour for longer and requires less frequent repainting.

Thermal Conductivity: Silicone render usually has a low thermal conductivity, meaning it provides good insulation for the building, aiding in maintaining a comfortable indoor environment and potentially lowering energy bills.

What is Monocouche Render?

Strength and Durability: Monocouche render is known for its strength and durability. Its cement and lime composition makes it a hard-wearing, long-lasting option. However, its robustness can also make it more prone to cracking in comparison to silicone render, especially in buildings that are subject to substantial movements.

Ease of Application: Monocouche render stands out for its ease of application. It’s a single-coat system, making the installation process quicker and simpler. This characteristic is particularly beneficial for large-scale projects where time efficiency is a priority.

Breathability: The breathability of monocouche render is one of its significant benefits. It effectively acts as a barrier against dampness while allowing moisture vapour to escape. This trait helps prevent moisture build-up within the building structure, protecting it from potential damp-related damage.

Aesthetics: Monocouche render is pigmented through and allows for a range of finishes, including scraped, roughcast, and tyrolean. Though the choice of colours might not be as extensive as the silicone render, the pre-coloured nature of the material means that a separate painting process isn’t required after the render has dried.

Silicone Render vs Monocouche Render


While both silicone and monocouche renders are durable, silicone render has a slight advantage due to its flexibility. This trait helps it resist cracks caused by building movement. Monocouche renders, while robust and hard-wearing, can be more susceptible to cracks if applied to buildings that experience significant movements or vibrations.


Monocouche render has a clear advantage when it comes to installation. It is a single-coat system, meaning it can be applied more quickly than the multi-layer silicone render system. This can lead to cost savings in terms of labour and time.


Both silicone and monocouche render systems are breathable, allowing for moisture vapour transmission. However, the breathability level can depend on the specific product chosen within these categories.


Silicone render often comes pre-mixed in a wide range of colours and finishes. It also retains its vibrant colour for a long time. Monocouche render also comes pre-coloured, but the choice of colours might not be as extensive as with silicone render.


Cost can vary depending on the specific product and manufacturer. However, while monocouche render might save on installation time, silicone render can often be less expensive in terms of material costs.

In conclusion, the choice between silicone render and monocouche render will largely depend on your specific project needs and constraints. Factors such as building type, climate, aesthetic preferences, budget, and project timeline will all play a part in this important decision. Always consult with a professional in the field to ensure you’re choosing the best render for your specific circumstances.
