Secondary Glazing
Secondary glazing adds an internal window layer to enhance thermal efficiency, noise reduction, and security. Our bespoke systems create insulating air gaps while preserving original window aesthetics. Ideal for listed buildings and modern properties requiring reversible solutions without structural alterations.
Horizontal Sliding
Horizontal sliding units feature smooth side-to-side operation, ideal for large windows with limited vertical space. These space-efficient systems provide effective thermal and acoustic insulation while maintaining easy access to primary windows for maintenance and ventilation.
Vertical Sliding
Vertical sliding solutions are designed for traditional sash windows, offering smooth up-down operation with optional tilt-in functionality. These units maintain heritage aesthetics while improving energy efficiency and security for period properties and conservation areas.
Hinged Units
Hinged secondary glazing opens like a door for easy access, perfect for frequent maintenance or ventilation needs. Customisable to various window sizes, these units provide excellent insulation while accommodating blinds and curtains with inward-opening design.
Fixed Installation
Fixed secondary glazing offers permanent, non-opening installation with discreet sightlines. These units deliver maximum thermal and acoustic performance for windows that don't require regular access, often combined with other styles in larger projects.
