Secondary Glazing NI were delighted to work on this beautiful period property in Belfast. The homeowners loved their original timber windows—they add charm, character and authenticity to the home. However, like many older windows, they also brought challenges: cold spots, draughts and outside noise.
Rather than replacing these stunning timber frames, the customer chose a smarter solution: secondary glazing. Our team installed discreet, made-to-measure units behind the existing windows, preserving the home’s appearance while significantly improving comfort.
The results speak for themselves. The home now benefits from:
- Increased warmth and energy efficiency
- Reduced draughts and outside noise
- Enhanced security
- Zero alteration to the original windows
For listed buildings, heritage homes and period properties, secondary glazing is an ideal way to upgrade performance without the disruption, cost or mess of replacing original frames. It offers all the modern benefits—while keeping the traditional look intact.
