Spray Cork Rendering for Thermal Insulation & Brick Protection. Case Study Outline:


1. Spray Cork Rendering for Thermal Insulation & Brick Protection - Project Overview.


  • Location: Rockbourne, Hampshire, UK

  • Client: Private homeowner

  • Project Duration: 2 weeks

  • Materials Used: CorkSol in Sage colour


This year, in October, we undertook an exciting two-week project in the charming village of Rockbourne, Hampshire. The property, a classic brick home, was in need of both functional and aesthetic improvements. The owner's main goal was to address two key concerns: improving thermal insulation and protecting the brickwork from weather damage.


By the end of the project, not only had the property been transformed visually, but it was also better equipped to handle the elements, delivering improved energy efficiency and enhanced durability for years to come.


2. The Challenge.


Every property comes with its own set of challenges, and this one was no exception.

First, thermal inefficiency was the owners' primary concern. The property was losing heat through its walls, especially during the colder months. With winter approaching, it was clear that something needed to be done to improve the property’s insulation so the family could stay warm without constantly cranking up the heating.


The next issue that needed addressing was the vulnerability of the brickwork. Over the years, the brick had started to show signs of wear and tear. Weathering from rain, wind, and fluctuating temperatures had left it looking tired, and worse, it was becoming more susceptible to moisture damage. Without action, this could lead to structural issues down the road—something we definitely wanted to prevent.


3. The Solution.


After evaluating the challenges, we knew we needed a solution that would tick all the boxes: practical, durable, and visually appealing. That’s when we recommended coloured spray cork insulation—a material that’s quickly gaining popularity for its perfect blend of style and functionality. Known for its unique combination of practicality and style, spray cork provided:


  • Thermal insulation

As property insulation, in this case, was one of the primary goals, spray cork delivered exactly what we needed. Thanks to its natural insulating properties, it significantly reduces heat loss, keeping the warmth inside the home and the cold out. Not only does this improve comfort, but it also helps make the property more energy-efficient, meaning the homeowners would see a reduction in energy bills, especially during the colder months.

  • Weatherproofing

When it comes to weather protection, spray cork works wonders. It creates a breathable barrier that’s both waterproof and moisture-resistant. The render prevents rainwater and moisture from seeping into the brickwork, but it also allows the structure to breathe, which helps avoid issues like damp or mould build-up inside the walls. This is essential for preserving the longevity of the home’s structure, especially in the unpredictable British weather.

  • Environment-friendly

An added bonus of choosing spray cork coating is that it’s an eco-friendly option. Made from natural materials, it aligns perfectly with the homeowner’s desire for a sustainable solution. Not only does it provide a high level of protection and insulation, but it also minimizes the environmental impact compared to more traditional rendering materials. It was the perfect choice for those who wanted to make their home more energy-efficient while staying mindful of their carbon footprint.

  • Aesthetics

On top of all these practical benefits, the Sage-coloured finish added a modern, fresh look to the home. It wasn’t just about functionality—it was also about enhancing the property’s appearance. The soft, natural tone of the Sage colour complemented the surrounding landscape beautifully, giving the home a sophisticated and stylish upgrade. The homeowners were thrilled with how the finish brought a contemporary feel while still blending in perfectly with its environment.


4. The Renovation Process.


Every step of the process was approached with meticulous care to ensure the best possible results for the homeowner.


  • Step 1

    Brick PreparationTo start with, we began by thoroughly cleaning the existing brickwork. We removed dirt and grime and filled existing cracks. This created a strong and smooth base for the spray cork application. To prevent any accidental overspray, we covered the adjacent areas.

  • Step 2

    Application of Spray Cork InsulationWe applied the cork in two layers using professional-grade equipment to ensure an even and durable finish.

  • Step 3

    Finishing TouchesOnce the render had cured, as always, we checked the rendering outcome to ensure consistency and high-quality results.

  • Step 4

    Clean-UpIn the end, we removed all equipment and protective coverings to make sure we left nothing but a beautifully finished home.


Throughout the process, the team communicated with the homeowners, keeping them updated and ensuring they were thrilled with each stage of the work.
