Services
Secondary Glazing
Our secondary glazing systems provide an effective solution for improving window performance without replacing existing units. By adding a discreet internal aluminium window, we create an insulating air gap that significantly enhances thermal efficiency, reduces external noise by up to 80%, and improves security. This reversible solution preserves original window aesthetics while delivering modern performance benefits for both residential and commercial properties.
Heritage Solutions
Specialist secondary glazing designed specifically for listed buildings and heritage properties. Our systems maintain strict conservation compliance by preserving original window structures while improving thermal insulation and acoustic performance. The non-invasive installation process ensures historical integrity remains intact, making this ideal for period homes, churches, and protected architectural sites requiring modern efficiency upgrades without compromising traditional aesthetics.
Noise Reduction
Targeted noise abatement solutions using secondary glazing technology to reduce external sound pollution. Our systems effectively minimise traffic, industrial, and environmental noise by up to 80%, creating quieter indoor environments for homes near busy roads and commercial spaces requiring acoustic control. The slim-profile aluminium frames maintain visual appeal while delivering significant sound insulation improvements.
Thermal Insulation
Enhanced thermal performance through secondary glazing installation, reducing heat loss by up to 60% compared to single-glazed windows. This energy-efficient upgrade lowers heating costs, improves indoor comfort, and contributes to reduced carbon emissions. The insulating air cavity works year-round to maintain stable indoor temperatures, making it an ideal solution for both cold climate protection and summer heat management.
Security Enhancements
Secondary glazing adds an extra protective layer to existing windows, significantly improving security against forced entry. The robust aluminium framing and toughened glass options create additional barriers without altering original window appearance. This solution is particularly beneficial for ground-floor properties, commercial premises, and heritage buildings where enhanced security must be balanced with aesthetic preservation and conservation requirements.
