Services
Horizontal Sliding
Horizontal sliding secondary glazing offers space-efficient window solutions for large or wide openings. Featuring smooth sliding panels, this system provides effective thermal and acoustic insulation without requiring vertical clearance. Ideal for properties with limited vertical space, it maintains original window aesthetics while enhancing energy efficiency and noise reduction. The mechanism allows easy access to primary windows for maintenance.
Vertical Sliding
Vertical sliding secondary glazing replicates traditional sash window aesthetics while improving performance. Designed for heritage properties, these units use tensioned balances for smooth vertical movement. They preserve architectural character in listed buildings while delivering modern benefits like enhanced thermal efficiency and noise reduction. Available with optional tilt-in functionality for easier cleaning and maintenance.
Tilt Vertical Sliding
Tilt vertical sliding glazing combines traditional sash aesthetics with modern functionality. The 45-degree tilt-in feature enables safe cleaning and full panel removal. This system maintains thermal efficiency and acoustic insulation while offering improved accessibility. Particularly suited for modern properties requiring both style and practical maintenance solutions without compromising on performance.
Hinged
Hinged secondary glazing units provide versatile access solutions for frequently used windows. Operating like a door, these units swing inward for ventilation and maintenance. They offer excellent insulation while accommodating various window sizes and configurations. Ideal for kitchens and utility areas where regular access is required, maintaining thermal efficiency without sacrificing functionality.
Lift Out
Lift-out secondary glazing panels offer discreet, high-insulation solutions for infrequent access needs. These removable units maintain thermal and acoustic performance while remaining unobtrusive when installed. Perfect for bay windows and tight spaces, the design allows easy removal for cleaning while preserving original window appearance and energy efficiency.
Questions
What is secondary glazing?
Secondary glazing is an internal window system added to existing windows, creating an insulating air gap that improves thermal efficiency, reduces noise, and enhances security without replacing original windows.
How does secondary glazing improve energy efficiency?
The insulating air cavity between primary and secondary glazing reduces heat loss by up to 60%, keeping interiors warmer in winter and cooler in summer while lowering energy bills.
Is secondary glazing suitable for listed buildings?
Yes, our reversible solutions preserve original window structures, making them ideal for listed properties where maintaining architectural heritage is crucial.
How long does installation take?
Installation typically takes 2-4 weeks from order confirmation, including bespoke manufacturing and professional fitting by approved installers.
What warranty do you offer?
All units come with a 10-year guarantee covering manufacturing defects, thermal performance, and acoustic insulation, ensuring long-term reliability and customer satisfaction.
