Secondary glazing involves installing an additional layer of glass or clear plastic inside your existing windows. This solution is perfect for those who wish to improve thermal insulation and reduce noise without altering the existing window frames. Secondary glazing is particularly appealing for listed properties or homes in conservation areas where changing the external appearance of buildings is restricted.Advantages of Secondary Glazing:- Improved heat retention, leading to reduced energy bills.
- Enhanced sound insulation which is ideal for homes in noisy environments.
- Minimal disruption during installation, as existing windows remain untouched.
- Less expensive than complete window replacements.

Double Glazing Replacements:
Replacing old windows with new double glazed units involves removing the existing frames and glass, replacing them with new ones that have two panes of glass separated by an inert gas layer. This modern solution is highly effective at insulating homes against both heat loss and external noise.Benefits of Double Glazing:- Superior thermal performance, which can significantly cut heating costs.
- Reduced condensation inside the window panes due to improved temperature regulation.
- Increased property value as double glazing is a desirable feature for home buyers.
- Variety in styles and frames, allowing customisation to suit your home's aesthetic.
