External Heat Control Window Film Installation at NatWest Bank, Spinningfields, Manchester

Project Overview

NatWest Bank's commercial office building in Spinningfields, Manchester, required a heat control solution to improve internal temperature regulation and reduce the strain on the air conditioning system. Following consultation with a structural engineer, Opalux External Specialist Heat Control Clear Film was selected as the ideal solution. Given the building's annealed glazing, using a traditional dark solar film was not an option due to the risk of thermal stress leading to potential glass breakage. 

Challenges & Solutions

• Planning Application Adjustments
  • Initially, the project was approved for only the top two floors. However, during the planning application process with Manchester City Council, it was advised that the film should be installed on all remaining floors. This increased the total coverage to 2000m². 
• Large Glass Panels & Height Considerations
  • The structural glazing panels were just under 7m² each, making installation complex, particularly at height. 
  • The BMU system allowed our team to safely apply the film externally while ensuring precise alignment and application. 
  • Our installation team worked methodically to minimise disruption while maintaining the highest safety standards. 
• Weather & External Elements
  • As with any external film installation, weather conditions played a crucial role. Our team closely monitored forecasts and scheduled work accordingly to avoid delays caused by wind or rain. 

Results & Client Feedback

The installation of Opalux External Specialist Heat Control Clear Film significantly reduced heat gain, helping to improve energy efficiency by reducing the strain on the building's air conditioning system. The film's optical clarity ensured that the aesthetic appearance of the glazing remained unchanged, preserving the building's original design. 

We are extremely pleased with the outcome of this project. The installation was carried out with great professionalism, and the team overcame the challenges of height and large glazing panels seamlessly. The heat reduction inside the building is noticeable, and we anticipate significant energy savings. The entire process, from consultation to completion, was handled exceptionally well. 

Conclusion

This project at NatWest Bank, Spinningfields exemplifies how strategic product selection and expert installation can overcome structural challenges and deliver long-term benefits. The combination of heat rejection and energy efficiency improvements will provide the client with a more comfortable working environment while supporting their sustainability objectives.
