Secondary glazing provides a significant improvement in property security alongside its acoustic and thermal benefits. An additional layer of glass and aluminium creates a substantial barrier against forced entry.
Windows are one of the most common entry points for burglars. Secondary glazing adds a second barrier that significantly increases the time and effort required to gain entry — a major deterrent against opportunist crime.
All hinged secondary glazing units are fitted with multi-point locking handles engaging the frame at multiple points simultaneously — far more secure than a single-point catch.
An intruder must break through two separate panes of glass. Additional noise and time increases detection risk. The aluminium frame and multi-point locking resist levering and prying. The inner secondary panel may not be visible from outside.
Laminated glass is available for enhanced security. The tough PVB interlayer holds glass together when broken, preventing penetration. Our acoustic laminate specifications (6.4–12.8mm) provide both outstanding noise reduction and enhanced security.
Improving window security can in some cases lead to reduced home insurance premiums. Contact your insurer to discuss.
