Project Overview
Pyramid successfully completed a comprehensive external wall insulation (EWI) project for a private homeowner in Cambridge seeking to reduce her heating bills and improve her property’s energy efficiency. The project transformed a standard residential property into a modern, energy-efficient home with enhanced aesthetics and comfort.
Client Background & Objectives
Melanie approached Pyramid Eco after conducting her own research into external wall insulation. Living on an estate where several properties had already received EWI through local authority schemes, she was familiar with the benefits but, as a private homeowner, wasn’t eligible for council-funded improvements.
Her primary objectives were:
- Reduce annual heating bills
- Improve home comfort and warmth
- Enhance property value and appearance
- Achieve better energy efficiency ratings for future refinancing opportunities
Why Pyramid?
Melanie discovered Pyramid Eco through our website. The decision to work with us was reinforced when we showed her examples of our previous work in the Hertfordshire area, demonstrating our track record of quality installations.
Technical Approach & Solution
After conducting a thorough site visit, our team identified several technical challenges that required careful planning:
System Selection: We recommended and installed the Webertherm xm system using mineral wool insulation at 110mm thickness, rather than the EPS (expanded polystyrene) systems common in the area. This decision was based on:
- Superior fire safety performance (our stance is that we don’t install EPS because of the fire risk)
- Better breathability for the building fabric
- Long-term value for property sales and refinancing
- Compliance with current regulations
Key Challenges Overcome:
- Conservatory Integration: Careful detailing around the existing rear conservatory, including complex guttering rerouting
- Thermal Bridge Prevention: Relocated fence panels and posts that would have created cold spots
- Structural Modifications: Safely removed a heavy concrete awning feature typical of these properties
- Roof Extensions: Extended the side elevation roofing to ensure complete weather protection
Project Investment & Funding
The total project cost was approximately £19,000, representing excellent value given the complexity of the work required. Through our expertise in funding applications, we secured GBIS (Great British Insulation Scheme) funding partially covering the costs, reducing Melanie’s investment.
Project Timeline
Despite the technical complexities, our experienced team completed the entire installation in just two weeks, minimising disruption to Melanie’s daily life.
Results & Benefits
Immediate Benefits:
- Dramatically improved property appearance – the home now stands out positively compared to neighbouring properties
- Enhanced thermal comfort throughout the home
- Improved energy performance reducing in lower heating bills
Long-term Value:
- 25-year insurance-backed guarantee in addition to Weber’s 10-year manufacturer warranty
- Improved EPC rating, beneficial for future property sales or remortgaging
- Potential for preferential mortgage rates as lenders increasingly favour energy-efficient properties
- Future-proofed against rising energy costs
Quality Assurance
Our installation comes with comprehensive protection:
- 10-year manufacturer’s guarantee from Weber
- 25-year insurance-backed guarantee covering system failure, even if the manufacturer or Pyramid ceased trading
- Full compliance with building regulations and industry standards
Client Satisfaction
Melanie was extremely pleased with the outcome, particularly appreciating:
- The professional approach to unexpected challenges
- Clear communication about additional costs when modifications were needed
- The superior finish compared to neighbouring properties with older EWI systems
- The minimal disruption despite the project’s complexity
Why Choose External Wall Insulation?
This project demonstrates why homeowners like Melanie are choosing EWI:
- Significant reduction in heating costs
