Vertu BMW Exeter – Superior Rendering with ProRend, ProBead and ProWall Systems

Vertu BMW Exeter, a prominent car dealership, undertook a major rendering project to enhance the aesthetic and thermal properties of the external aspects of their showroom. McCarthy Contractors spearheaded the application, utilising SAS Render Systems flagship products ProRend, ProBead and ProWall to achieve a seamless and durable finish.

BMW Showroom

Project Requirements

The project had specific requirements to ensure a high-quality and long-lasting result:

  • Repair Section: 100mm EPS insulation system affixed back to the steel frame on the main roadside.
  • Front Façade: ProWall system affixed to aluminium top hat sections.
  • Final Finish: ProRend Colourtex thin coat finish matching the existing colour, RAL 9001.
  • Comprehensive Involvement: Involvement throughout the project for all aspects of the project.


100mm EPS Insulation System

For the repair section at the main roadside, a 100mm premium EPS insulation system was installed. This system was affixed back to the steel frame, ensuring improved thermal performance.

ProWall System

For the front façade, the ProWall system was chosen for its outstanding performance and longevity. The system was affixed to aluminium top hat sections, providing a robust and durable solution that seamlessly integrated with the existing structure.

  • Long-Term Durability: The ProWall system comes with a 60-year BBA certificate, guaranteeing its durability.
  • Fire Performance: Delivers first-class performance concerning fire resistance, ensuring safety and compliance with regulations.
  • Strength and Stability: Provides exceptional strength and stability, maintaining its structural integrity over time.
  • Weather Tightness: Effectively protects the building from the elements, ensuring longevity and minimal maintenance.
  • Healthy Air Quality: The rendered rainscreen cladding maintains healthy air quality by allowing the building to breathe while protecting it from the elements.

Colourtex Finish

    The final finish was crucial for maintaining the dealership's aesthetic consistency. ProRend Colourtex, a premium factory-batched proprietary silicone resin thin-coat render, was selected for its high water resistance and low maintenance requirements. This finish was applied over a ProRend coloured primer and perfectly matched the existing RAL 9001 colour.
