Thermal Proof
Independent UK research consistently shows that well-designed shutters can significantly reduce heat loss through windows. Studies from the BBSA/University of Salford, University of Brighton, and Historic Scotland provide reliable, proven evidence of heat-loss reduction ranging from 20–30%, with higher-performance systems achieving even greater results.
Your home will receive a before-and-after Thermal Imaging Survey, giving you visible proof of how effectively your shutters help retain warmth.
UK Testing Only Applies to UK-Specified Products
Independent UK testing has only been carried out on British-made or British-specified shutter systems.
Imported shutters have never been included in these tests, so no independent data exists to confirm their thermal performance, insulation ability, or long-term behaviour.
That’s why our ThermaCore system is engineered to align with — and exceed — the performance benchmarks proven in UK research.
What You’ll See on Thermal Imaging:
Less heat leaking through glazing
Reduced cold bridging around the frame
Fewer drafts and cold patches
Improved internal temperature stability
Energy Efficiency
Fitting insulated shutters across around 10 m² of window area can contribute to meaningful long-term heating savings by reducing the amount of warm air lost through windows.
Every home will see some level of measurable thermal improvement — confirmed by real-time thermal imaging.
