Challenge
The park home suffered from poor thermal performance typical of older lightweight residential structures. Heat loss through external walls resulted in high energy consumption and increased heating costs. The property also needed to improve its EPC rating to align with evolving energy efficiency standards. The key challenge was improving building performance without major structural alterations.
Approach
Tomil developed a targeted retrofit strategy centred around the installation of a high-performance external wall insulation system. The design focused on improving the thermal envelope while maintaining the building’s structural integrity and appearance. Careful detailing ensured compatibility with the existing construction. The retrofit approach prioritised measurable energy improvements with minimal disruption to the property.
Solution
The retrofit successfully enhanced the building’s thermal performance, improving the EPC rating from E to D. External wall insulation significantly reduced heat loss and improved indoor comfort levels. The upgrade also lowered projected energy consumption and heating costs for occupants. The project demonstrates how focused retrofit interventions can extend building life while improving environmental performance.
