Secondary Glazing Security Windows - Home Window Security Measures and Security Glazing


Security Windows - Home & Commercial Window Security

This section deals with Secondary Glazing for Security Windows in Homes and in the thousands of older traditional Commercial Buildings throughout London and the Home Counties.

Home & Commercial Window Security

Burglaries are on the Increase, Secondary Glazing London

The rate of domestic and commercial burglaries has been steadily increasing - most are “spur of the moment” crimes, rather than planned, professional, determined attacks.

Unless they were designed with security in mind, most window systems offer little real protection against forced entry - and they are often a weak point in a property’s security.

This is particularly true of the windows in many older homes and commercial premises.

Properties with original single glazed windows & older types of double glazing offer “soft targets” for the opportunistic burglar and are especially vulnerable.

Home Security - Windows - The Risks - Casement & Sash Window Security

Sash Window Security - they are Especially Vulnerable, Secondary Glazing London

Old glass becomes brittle and is easily broken and then old fashioned non-locking catches and stays can be simply released to open the windows.

Most at risk are:

  • all traditional sash windows - sash window security is notoriously poor
  • all ground floor rear windows
  • any window not visible to neighbours
  • small bathroom windows
  • traditional French doors
  • old double glazing with external glazing beads
  • old double glazing with simple “clip-over” handles
  • older patio doors without anti-lift or multi-point locking security

Commercial Properties - Windows - Risks & Applications

Older Commercial Premises - Window Security is a Weak Point, Secondary Glazing London

Risks and Applications:

Huge amounts of historic city centre office and commercial accommodation is particularly vulnerable due to retaining the original, low security windows - which may also be subject to Listed Building or Conservation Area status, thus preventing replacement.

  • vulnerable windows that are easily accessible but not generally overlooked outside of normal working hours - typically ground floor & at the rear or sides of premises
  • sensitive areas - such as for data, server & communication installations - where any unauthorised entry & subsequent vandalism or theft can be hugely damaging for the organization
  • added protection for high profile individuals & their families in Company accommodation
  • protection against industrial/commercial espionage
  • added protection for areas containing either artistic or commercial items of value
  • increased security for organizations involved in sensitive areas of research & development

Window Security Risks - The Solutions

Window security measures fall into three categories:

  • make your property more secure than neighbouring properties, thereby making it less of a target - window and door security is the number one priority
  • anything that makes it more difficult, time consuming or noisy to get in is both a deterrent and makes it less likely that a burglar will successfully gain entry
  • at home, if your property is occupied, then the more warning you have from the noise the more time you have to respond - call the police and lock yourself and your family into a bedroom
