Thermal Glazing Efficiency Solutions
Dramatically improve your home's thermal efficiency with our specialist secondary glazing solutions. Reduce heat loss by up to 70% and cut energy bills while maintaining your existing windows.
Common Heat Loss Problems
Understanding where and why your home loses heat through windows
Single pane windows offer minimal thermal resistance, allowing heat to escape easily
Gaps around window frames allow cold air in and warm air out
Metal window frames conduct heat directly from inside to outside
Inefficient windows can account for 25% of total heat loss in homes
How Secondary Glazing Improves Thermal Efficiency
The science behind secondary glazing's thermal performance benefits
Insulating Air Gap
Creates a thermal barrier between your existing window and the secondary glazing
Reduced Convection
Minimizes air movement and heat transfer through convection currents
Improved U-Values
Significantly reduces the U-value (heat transfer coefficient) of your windows
Draught Elimination
Seals gaps and prevents cold air infiltration around window frames
