This system produces a cavity of air in between the two panes, which serves as a powerful insulator against both thermal transfer and sound waves. Since it is thought about a reversible internal change, it is the preferred choice for heritage organizations and local preparation authorities.


The Core Benefits of Secondary Glazing

The decision to buy secondary glazing is hardly ever based upon visual appeal alone. It is a practical upgrade designed to deal with a number of common residential and commercial complaints.

  • Thermal Insulation: By adding an extra layer of glass and developing an insulating air space, heat loss through windows can be reduced by up to 60%. This results in decrease energy bills and a smaller carbon footprint.
  • Acoustic Reduction: Secondary glazing is arguably the most effective method for sound cancellation. A substantial space (generally 100mm to 200mm) between the old and new glass can minimize external noise levels by as much as 80% (approx. 50 decibels).
  • Condensation Control: By supplying a seal that avoids warm, wet indoor air from hitting the cold surface area of the main window, secondary glazing substantially minimizes the threat of condensation and subsequent mold growth.
  • Improved Security: An additional internal window functions as a secondary physical barrier versus intruders, making it substantially harder to gain unapproved access to the property.
  • Cost-Effectiveness: Compared to the wholesale replacement of original wood sashes or stone-mullioned windows, secondary glazing is a portion of the expense.
