what is secondary glazing
Secondary glazing is a discreet, internal window that enhances your existing window’s performance.
By adding a second, ultra-slim aluminium window to the room side of an existing window, secondary glazing creates an air cavity. Just like double-glazing, the combination of glass and air cavity provides an effective barrier to heat loss and noise, while the window itself adds a second layer of security.

- Thermal Efficiency — Keep your home warmer
- Cost-Effective Alternative — No need to replace windows
