How secure are sliding and bi-folding glass doors?

How secure are sliding and bi-folding glass doors? This question crops up frequently during our discussions with customers, and it’s easy to understand why.

Sliding doors, bi-folding doors and alu-clad doors can look amazing either on their own or as part of a Wintergarden design. They flood your home with light and offer uninterrupted views of the outdoors. During the warmer months, they are perfect for making the most of your patio, garden or terrace, providing a seamless transition between your indoor living area and outside space.

As more and more people look to add the wow factor to their property and blur the lines between their home and garden, demand is growing for glazing systems with as much glass and the slimmest frames possible.

But this means a large expanse of exterior glass will likely be added to your property – and it’s not unreasonable to wonder what the implications are for the security of your home.


What factors affect the security of glass doors?

There are a number of factors that affect how secure a sliding glass door or bi-folding door is. In a nutshell, the strength of the glass and the frames, as well as the lock system, can all have a bearing on the level of security provided.

A strong locking mechanism is essential, while aluminium frames in particular are extremely robust. Laminated or safety glass that’s designed to hold together instead of shattering can also help improve the security of your glass door and delay or prevent an intruder from entering your home.

You can also implement other measures to step up the security of your sliding door or bi-folding door, such as obscuring the view through the panes with frosted glass or blinds. Another option is to install a security alarm connected to your glass doors.

How do you know a glass door system is secure?

There are various security accreditations and standards that you can look out for to check how secure your sliding or bi-folding doors are.

Here in the UK, there is a British minimum standard for security for new build homes called PAS 24. It is designed to assess the protection level of doors and windows against opportunistic burglaries.

PAS24 is achieved following thorough testing and assessment for enhanced security performance. It is carried out by the United Kingdom independent testing bodies that ensure doors and windows are compliant and adhere to building regulations.

EN 1627:2011, meanwhile, is the European standard assessing the burglar resistance of door and window systems in domestic and commercial properties. There are six levels of classification under this standard, with RC2 and RC3 levels covering domestic properties and indicating resistance to opportunistic burglars using tools such as screwdrivers and pliers.

In addition, Secured by Design is a UK accreditation initiative operating on behalf of the British Police. It aims to improve the security of buildings and their immediate surroundings and provide safe places to live, work, shop and visit. The certification is given to products which meet a security standard following further independent testing.

Additional features such as electro-mechanical locking elements, broken glass sensors, monitors, and even integration into your security alarm system, can provide further reassurance.

Cero sliding doors are tested and certified to security standards laid down by the British Standards Institute (BSI). They are classified as fulfilling the RC2 level of burglar resistance, specifically with regard to forced entry by casual or opportunistic intruders. RC3 is also available as a further enhanced option.

In addition, the Solarlux Cero II sliding door has been recently tested and certified here in the UK for PAS 24 security standards.
