SPECIALISTS IN BESPOKE SECONDARY GLAZING FOR THE HERITAGE SECTOR
Curved-in-plan secondary glazing is designed for windows that follow a curved, bowed, circular, or radius layout when viewed from above. These architectural features are often found in heritage buildings, period properties, listed buildings, churches, museums, commercial developments, and high-end residential projects where preserving the original window appearance is essential.
Our bespoke curved secondary glazing systems are manufactured to match the exact geometry of your existing windows, delivering enhanced thermal performance, acoustic insulation, and draught reduction without compromising the character of the building.
Unlike standard flat secondary glazing units, curved-in-plan systems are engineered to follow the horizontal curvature of the primary window. The secondary frame is precisely manufactured to mirror the existing radius, creating a discreet internal glazing solution that integrates seamlessly with the original architecture.
Each installation is individually designed using detailed site surveys and manufacturing techniques that ensure a perfect fit, even for complex curved elevations and bay window arrangements.
Curved-in-plan secondary glazing is suitable for:
Curved bay windows
Radius and bow-fronted windows
Circular and semi-circular glazed elevations
Heritage and listed buildings
Churches and historic properties
Museums and galleries
Hotels and hospitality venues
Luxury residential developments
Commercial office buildings
Superior Noise Reduction
Create a quieter internal environment by significantly reducing external noise from traffic, railways, aircraft, and busy urban areas. The enhanced air gap between the existing window and secondary glazing provides exceptional acoustic performance.
Improved Thermal Efficiency
Reduce heat loss through older single-glazed windows and improve overall energy efficiency. Secondary glazing helps maintain comfortable indoor temperatures throughout the year while lowering heating costs.
Preservation of Historic Features
Ideal for listed buildings and conservation projects where replacing original windows is not permitted. Curved secondary glazing maintains the appearance and integrity of existing windows while delivering modern performance benefits.
Reduced Draughts
Eliminate cold spots and uncomfortable draughts around traditional windows, improving occupant comfort without altering the original structure.
