Different Types of Render for Solid Wall Insulation

There are several different types of render that can be used for solid wall insulation, including lime render, cement render, silicone render, acrylic render, and polymer render.

Lime Render

Lime render is great for old homes. It helps your walls breathe and keeps damp away. Lime mix has sand, water, and lime in it. This type of render doesn't crack much because it's flexible.

Using lime render can keep the beauty of old homes alive while making them strong too.

Cement Render

Cement render is one of the types of render used for solid wall insulation. It is made from a mixture of cement, sand, and water. This type of render is strong and durable, making it suitable for both external and internal walls.

Cement render provides good weather resistance and helps to protect the underlying structure from moisture damage. It can also be mixed with additives to enhance its properties, such as improving flexibility or reducing cracking.

Overall, cement render is a popular choice because it offers excellent strength and longevity for solid wall insulation projects.

Silicone Render

Silicone render is a type of render that offers many benefits for solid wall insulation. It is made up of silicone, which makes it flexible and durable. This means that it can withstand different weather conditions without cracking or fading.

Silicone render also has excellent water repellency, which helps to protect your walls from dampness and moisture damage. It is also self-cleaning, as rainwater washes away any dirt or pollutants that may accumulate on the surface.

Another advantage of silicone render is that it comes in a wide range of colors and finishes, allowing you to achieve the desired look for your property. Overall, silicone render provides a long-lasting and low-maintenance solution for external wall insulation.

Acrylic Render

Acrylic render is a popular choice for solid wall insulation because it offers excellent durability and flexibility. It is made from a mix of acrylic resin, sand, and water, which creates a strong and long-lasting finish.

The application process involves applying two layers of the render onto the external walls. The first layer acts as a basecoat to fill any imperfections on the surface, while the second layer provides a smooth and even finish.

Acrylic render is available in various colors and textures, allowing you to achieve your desired aesthetic result. It also provides good weather resistance, preventing moisture from penetrating through the walls.

Polymer Render

Polymer render is a type of render that is gaining popularity for solid wall insulation. It is made from a mix of acrylic resin and sand, which gives it flexibility and durability.

This means that it can withstand movement in the building without cracking or breaking. Polymer render is also water-resistant, making it suitable for use in areas that are exposed to rainwater or high humidity.

It can be applied as a two-layer system, with an insulated base layer and a decorative topcoat. The use of polymer render can improve the thermal efficiency of your property, helping to reduce heat loss and save on energy bills.

Factors Affecting Render Choices

Different factors, such as property age, existing substrate, and desired finish and colour, can greatly influence the choice of render for solid wall insulation.

Property Age

When it comes to choosing the right type of render for solid wall insulation, the age of your property is an important factor to consider. Older properties might require a more traditional and breathable render, such as lime render, which allows moisture to evaporate from the walls.

Lime render is ideal for older buildings with solid walls as it helps prevent dampness and damage. On the other hand, newer properties can benefit from modern renders like silicone or acrylic renders that offer excellent weather resistance and durability.

Considering the age of your property will help you make an informed decision about which type of render is best suited for your solid wall insulation needs.

Existing Substrate

The existing substrate refers to the surface that the render will be applied to. It could be brick, concrete, or another type of material. The condition and type of substrate can affect the choice of render.

For example, if the substrate is porous or has a rough texture, a lime render may be more suitable as it allows for better breathability and adherence. On the other hand, if the substrate is smooth and non-porous, a cement or acrylic render may be used instead.

It's important to consider the existing substrate when selecting the right type of render for solid wall insulation to ensure proper adhesion and durability.

Desired Finish and Colour

When choosing the type of render for solid wall insulation, it's important to consider your desired finish and colour. Different types of render offer different finishes and colours, allowing you to achieve the look you want for your property.

For example, acrylic render is available in a wide range of colours and has a smooth finish, while silicone render offers a textured finish with even more colour options. Cement render can also be tinted to create various shades.

By considering your desired finish and colour, you can choose the right type of render that will enhance the appearance of your property.

Comparison of Render and Solid Wall Insulation

- Render and solid wall insulation differ in terms of cost, thermal efficiency, and upkeep and maintenance requirements.

- The cost of render varies depending on the type chosen, with acrylic and polymer renders generally being more expensive than cement or lime renders.

- Solid wall insulation provides superior thermal efficiency compared to render alone, as it involves the installation of physical insulation boards.

- When it comes to upkeep and maintenance, render may require occasional repairs or repainting, whereas solid wall insulation is typically more durable and requires less ongoing maintenance.

Cost Difference

Choosing the right type of render for solid wall insulation can make a big difference in terms of cost. Some renders, like cement render and lime render, are generally more affordable compared to others like acrylic render or silicone render.

While the initial cost may be lower with traditional renders, it's important to consider long-term factors such as maintenance and energy efficiency. Insulating renders, although they may have a higher upfront cost, provide additional thermal benefits that can potentially reduce energy bills in the long run.

So when considering the cost difference between different types of render, it's crucial to weigh the initial expense against potential savings and benefits over time.

Thermal Efficiency

When it comes to solid wall insulation, thermal efficiency is an important factor to consider. Different types of render can have varying levels of thermal performance.

Thermal efficiency refers to how well a material can prevent heat transfer. Insulation specialists recommend using render that has good thermal properties, as it helps to retain heat within the property during colder months and keeps the interior cooler in warmer weather.

Polymer renders, such as acrylic and silicone renders, are known for their excellent thermal properties. They provide a high level of insulation, keeping your home warm in winter and cool in summer.

On the other hand, cement render may not provide as much insulation compared to polymer renders. However, if you combine cement render with physical insulation boards or other forms of solid wall insulation, you can still achieve good thermal efficiency.

Upkeep and Maintenance

We understand that you want to know how to maintain the render on your solid wall insulation. It's important to regularly check the condition of your render and address any issues promptly.

Keep an eye out for cracks, chips, or peeling, as these can allow moisture to seep in and damage the insulation. You can clean your render with a gentle detergent solution, but avoid using high-pressure washers as they can damage the surface.

If you notice any major problems with your render, it's best to contact professionals who specialize in rendering and insulation to assess and fix the issue.

Conclusion

In conclusion, understanding the different types of render for solid wall insulation is crucial for making informed choices. Each type of render, such as lime render, cement render, silicone render, acrylic render, and polymer render, has its advantages and considerations.

Factors like property age, existing substrate, and desired finish play a role in selecting the right type of render. By considering these factors and comparing them to solid wall insulation options, customers can make decisions that align with their needs and budget while ensuring thermal efficiency and easy maintenance.
