INTERNAL WALL INSULATION CASE STUDY
Internal Wall Insulation Upgrade – Luton Residential Property
AEG delivered a comprehensive internal wall insulation upgrade at a residential property in Luton, combining high-performance insulation with modern heating controls to improve thermal retention, reduce heat loss, and enhance overall energy efficiency.
PROJECT OVERVIEW
A combined insulation and heating control upgrade designed for stronger thermal performance
This project focused on improving the thermal efficiency of a residential property in Luton through the installation of an internal wall insulation system and upgraded heating control components. The aim was to reduce heat loss through internal wall areas, support improved temperature retention, and create a more comfortable indoor environment.
AEG installed the SWIP Internal Wall Insulation System alongside modern heating controls to ensure the property benefits not only from better insulation performance, but also from more efficient heating management and greater day-to-day control.
Improved thermal resistance through insulated wall build-up
Reduced heat transfer and stronger indoor temperature retention
Integrated heating controls for more efficient energy use
Project Details
EXISTING PROPERTY CONDITION
Addressing heat loss, limited wall insulation, and inefficient heating control
Prior to the upgrade, the property experienced notable heat loss through uninsulated internal walls, leading to reduced thermal retention during colder months and lower overall indoor comfort. The existing setup also offered limited heating control, which contributed to inefficient energy use.
These issues affected both performance and practicality. The property required a solution that could improve insulation levels while also enhancing heating management, helping reduce unnecessary heat usage and strengthening the home’s overall efficiency.
Before Upgrade
Uninsulated internal walls, reduced thermal retention, and less efficient heating use.
Main Objective
Improve wall insulation and install modern controls for better comfort and lower energy demand.
INSULATION SOLUTION
A high-performance internal wall insulation system integrated with efficient heating controls
Internal Wall Insulation
AEG installed the SWIP Internal Wall Insulation System across key internal wall areas to improve thermal resistance and reduce heat transfer through the building fabric.
Heating Control Upgrade
Modern heating control components were integrated to support more intelligent temperature regulation and improve heating performance across the property.
Performance Optimisation
Final calibration and performance checks were completed to ensure the installed measures work together effectively and deliver improved efficiency with minimal disruption.
INTERNAL WALL INSULATION SYSTEM
Installed to reduce heat loss and improve indoor temperature stability across key areas
The internal wall insulation system was designed to improve the thermal efficiency of the property by reducing heat loss through wall surfaces and strengthening indoor temperature retention. This helps create a more stable internal environment and supports lower heating energy requirements.
The system was integrated carefully within the existing structure to provide strong performance benefits while maintaining practical installation standards and a clean finished appearance.
Enhanced thermal resistance
Reduced heat transfer through walls
Improved indoor temperature retention
Seamless integration with existing structure

HEATING CONTROL ENHANCEMENT
Modern controls installed to support efficient heat distribution and smarter temperature management
Alongside the insulation works, AEG installed upgraded heating control components to help optimise heat distribution and improve how the property uses heating energy day to day. This allows the system to respond more effectively to indoor demand.
Installed components included Secure Meter C1727, RADBOT1 thermostatic controls, ERP Class V111 controls, and standard lockshield valves, helping deliver better temperature regulation and more controlled heating performance.
Intelligent temperature regulation
Improved radiator performance
Reduced unnecessary heating usage
Greater control over indoor climate
HEATING SYSTEM COMPONENTS
Installed controls and radiator components supporting better heating efficiency
The heating control package forms an important part of the project outcome by helping ensure that improved insulation performance is matched by more efficient heating management. This supports stronger day-to-day usability and reduced unnecessary energy consumption.

BEFORE & AFTER
From bare internal wall surfaces to a clean insulated and finished interior
ENERGY PERFORMANCE IMPROVEMENT
A substantial uplift in energy efficiency through insulation and optimised heating control
Pre-Installation Rating
The property had a pre-installation EPC rating of E (54), reflecting weaker thermal efficiency and heat retention performance.
Post-Installation Rating
Following the upgrade, the property achieved a stronger EPC rating of C (75), demonstrating a measurable improvement in energy performance.
Project Impact
The completed works improved thermal efficiency, reduced heating demand, and aligned the property more closely with modern energy standards.
PROJECT IMPACT
Reduced wall heat loss, improved temperature stability, and stronger overall comfort
The completed internal wall insulation project demonstrates how insulation and heating control upgrades can work together to create a better-performing residential environment. The property now benefits from reduced heat loss, improved indoor temperature stability, and lower overall heating energy requirements.
This balanced approach improves performance while supporting everyday comfort for occupants, making the property more efficient, more practical, and better suited to current energy expectations.
