Secured by Design Rooflights

Part Q Compliant Secured by Design glass rooflights tested to LPS2081:1 2015

Security isn’t something you leave to chance, you should ensure that all windows, doors and rooflights are secure by specifying the right product for the job.

Glazing Vision’s Secure and Secure+ range of rooflights have been exhaustively tested against LPS2081 Issue 1:2015 standards to comply fully with Building Regulations Approved Document Q – Security in Dwellings.

LPS2081 Issue 1:2015 is specifically designed to replicate the types of stealth attack common to domestic properties, if you are considering installing rooflights that could be deemed as ‘easily accessible’ under the criteria set out in Approved Document Q, then you must specify a product that has been tested to one of the relevant standards in order to comply with Building Regulations.

LPS2081 Issue 1:2015 was created by the Building Research Establishment (BRE) and introduced in 2015 in order to address the types of stealth attack commonly carried out in residential areas.

The attacks are designed to represent an opportunist intruder attempting to use a combination of physical bodily force , stealth and a selection of tools that are easily concealed about the person in order to gain entry.

The standard is certificated by The Loss Prevention Certification Board (LPCB) which has been working with industry and government for more than 100 years setting standards to ensure that security products perform effectively. LPCB offers third party independent approval confirming products have met and will continue to meet these standards.

LPCB approved products reduce security risks and demonstrate due diligence and the use of approved products is encouraged by insurers.

Secured by Design was established in 1989 and is the UK Police flagship security initiative which combines the principals of ‘designing out crime’ through physical security and layout across all realms of the built environment.

Secured by Design works with industry test houses to create and test high level security standards in response to trends in crime. Where a product manufacturer has successfully passed relevant security testing to an approved standard, it can then apply to have that product marked with the SBD logo.

Although a product may in principal be secure and good enough to pass these standards, unless it has been tested and certificated it cannot use the Secured by Design mark and will not be supported by the Police.

Glazing Visions Secure and Secure+ rooflight range are the first to be tested against the new standard LPS2081 Issue 1:2015.

You can be assured that where you see the Secured by Design logo, your product will be able to withstand a sustained attack by the most determined of intruders. View our Secured by Design certificate here.

Flushglaze Secure+

Glazing Vision offer two types of product that identify which level of attack they have been tested to:

Glazing Vision Secure rooflights have been tested to LPS2081 security rating A which means they are designed to withstand an attack for up to 1 minute.

Glazing Vision Secure+ rooflights have been tested to security rating B and can withstand an attack of up to 3 minutes.

The attacks are carried out in a controlled environment and cover glass, framework and mechanical fixings.

Glass can break, but should remain intact enough to prevent an intruder gaining entry into the building, so a laminated inner pane is required to maintain the structural integrity of the glass for the required time.

This footage of tests carried out on our Flushglaze Secure+ rooflight demonstrates that although the outer toughened panel eventually breaks, the inner laminated pane can withstand an attack for much longer and in this case achieves security rating B.

In some cases glass rooflights will be specified and manufactured in modular sections, which include internal framework to support the joints between glazed panels.

In this example two sections of our modular Flushglaze rooflight is supported by an aluminium back-to-back angle which is welded to the main perimeter frame. This type of support provides enough strength to prevent the intruder gaining entry for up to three minutes, at which point the test is stopped and the product awarded a class B (highest) rating and can be identified as one of our ‘Secure+’ products.

VisionVent Secure

Opening rooflights are sometimes considered less secure than fixed because of their potential to be forced open, but this will depend on how the opening section is secured shut.

Many opening rooflights do not have the same level of locking systems when compared to doors and windows, because in most cases they are not as easily accessible.

But with the increase in single storey home extensions meaning that more accessible rooflights are finding their way into buildings, the security of an opening rooflight should be carefully considered.

In this test an electrically hinged VisionVent rooflight is subjected to the usual attacks on its glass, which it easily passes due to the inclusion of a laminated inner pane.

Further attempts are then made to forcibly pry open the lid section, which results in failure because of the dual mechanical operating system housed within either end of the frame.

These mechanisms provide two solid locking points and their design prevents the rooflight being back driven™, thus rendering the unit locked shut unless activated by a control switch which is safely housed inside the building.

Locking points can often be the weak link in rooflight design and careful consideration should be given when specifying this type of product in a high-risk area.
